1 Pages and API endpoints The Datasette web application offers a number of different pages that can be accessed to explore the data in question, each of which is accompanied by an equivalent JSON API. 1  
2 Top-level index The root page of any Datasette installation is an index page that lists all of the currently attached databases. Some examples: fivethirtyeight.datasettes.com global-power-plants.datasettes.com register-of-members-interests.datasettes.com Add /.json to the end of the URL for the JSON version of the underlying data: fivethirtyeight.datasettes.com/.json global-power-plants.datasettes.com/.json register-of-members-interests.datasettes.com/.json 1  
3 Database Each database has a page listing the tables, views and canned queries available for that database. If the execute-sql permission is enabled (it's on by default) there will also be an interface for executing arbitrary SQL select queries against the data. Examples: fivethirtyeight.datasettes.com/fivethirtyeight global-power-plants.datasettes.com/global-power-plants The JSON version of this page provides programmatic access to the underlying data: fivethirtyeight.datasettes.com/fivethirtyeight.json global-power-plants.datasettes.com/global-power-plants.json 1  
4 Table The table page is the heart of Datasette: it allows users to interactively explore the contents of a database table, including sorting, filtering, Full-text search and applying Facets . The HTML interface is worth spending some time exploring. As with other pages, you can return the JSON data by appending .json to the URL path, before any ? query string arguments. The query string arguments are described in more detail here: Table arguments You can also use the table page to interactively construct a SQL query - by applying different filters and a sort order for example - and then click the "View and edit SQL" link to see the SQL query that was used for the page and edit and re-submit it. Some examples: ../items lists all of the line-items registered by UK MPs as potential conflicts of interest. It demonstrates Datasette's support for Full-text search . ../antiquities-act%2Factions_under_antiquities_act is an interface for exploring the "actions under the antiquities act" data table published by FiveThirtyEight. ../global-power-plants?country_long=United+Kingdom&primary_fuel=Gas is a filtered table page showing every Gas power plant in the United Kingdom. It includes some default facets (configured using its metadata.json ) and uses the datasette-cluster-map plugin to show a map of the results. 1  
5 Row Every row in every Datasette table has its own URL. This means individual records can be linked to directly. Table cells with extremely long text contents are truncated on the table view according to the truncate_cells_html setting. If a cell has been truncated the full length version of that cell will be available on the row page. Rows which are the targets of foreign key references from other tables will show a link to a filtered search for all records that reference that row. Here's an example from the Registers of Members Interests database: ../people/uk.org.publicwhip%2Fperson%2F10001 Note that this URL includes the encoded primary key of the record. Here's that same page as JSON: ../people/uk.org.publicwhip%2Fperson%2F10001.json 1

7 Play with a live demo The best way to experience Datasette for the first time is with a demo: global-power-plants.datasettes.com provides a searchable database of power plants around the world, using data from the World Resources Institude rendered using the datasette-cluster-map plugin. fivethirtyeight.datasettes.com shows Datasette running against over 400 datasets imported from the FiveThirtyEight GitHub repository . 1  
8 Try Datasette without installing anything using Glitch Glitch is a free online tool for building web apps directly from your web browser. You can use Glitch to try out Datasette without needing to install any software on your own computer. Here's a demo project on Glitch which you can use as the basis for your own experiments: glitch.com/~datasette-csvs Glitch allows you to "remix" any project to create your own copy and start editing it in your browser. You can remix the datasette-csvs project by clicking this button: Find a CSV file and drag it onto the Glitch file explorer panel - datasette-csvs will automatically convert it to a SQLite database (using sqlite-utils ) and allow you to start exploring it using Datasette. If your CSV file has a latitude and longitude column you can visualize it on a map by uncommenting the datasette-cluster-map line in the requirements.txt file using the Glitch file editor. Need some data? Try this Public Art Data for the city of Seattle - hit "Export" and select "CSV" to download it as a CSV file. For more on how this works, see Running Datasette on Glitch . 1  
9 Using Datasette on your own computer First, follow the Installation instructions. Now you can run Datasette against a SQLite file on your computer using the following command: datasette path/to/database.db This will start a web server on port 8001 - visit http://localhost:8001/ to access the web interface. Add -o to open your browser automatically once Datasette has started: datasette path/to/database.db -o Use Chrome on OS X? You can run datasette against your browser history like so: datasette ~/Library/Application\ Support/Google/Chrome/Default/History Now visiting http://localhost:8001/History/downloads will show you a web interface to browse your downloads data: http://localhost:8001/History/downloads.json will return that data as JSON: { "database": "History", "columns": [ "id", "current_path", "target_path", "start_time", "received_bytes", "total_bytes", ... ], "rows": [ [ 1, "/Users/simonw/Downloads/DropboxInstaller.dmg", "/Users/simonw/Downloads/DropboxInstaller.dmg", 13097290269022132, 626688, 0, ... ] ] } http://localhost:8001/History/downloads.json?_shape=objects will return that data as JSON in a more convenient format: { ... "rows": [ { "start_time": 13097290269022132, "interrupt_reason": 0, "hash": "", "id": 1, "site_url": "", "referrer": "https://www.dropbox.com/downloading?src=index", ... } ] } 1  
10 datasette --get The --get option can specify the path to a page within Datasette and cause Datasette to output the content from that path without starting the web server. This means that all of Datasette's functionality can be accessed directly from the command-line. For example: $ datasette --get '/-/versions.json' | jq . { "python": { "version": "3.8.5", "full": "3.8.5 (default, Jul 21 2020, 10:48:26) \n[Clang 11.0.3 (clang-1103.0.32.62)]" }, "datasette": { "version": "0.46+15.g222a84a.dirty" }, "asgi": "3.0", "uvicorn": "0.11.8", "sqlite": { "version": "3.32.3", "fts_versions": [ "FTS5", "FTS4", "FTS3" ], "extensions": { "json1": null }, "compile_options": [ "COMPILER=clang-11.0.3", "ENABLE_COLUMN_METADATA", "ENABLE_FTS3", "ENABLE_FTS3_PARENTHESIS", "ENABLE_FTS4", "ENABLE_FTS5", "ENABLE_GEOPOLY", "ENABLE_JSON1", "ENABLE_PREUPDATE_HOOK", "ENABLE_RTREE", "ENABLE_SESSION", "MAX_VARIABLE_NUMBER=250000", "THREADSAFE=1" ] } } The exit code will be 0 if the request succeeds and 1 if the request produced an HTTP status code other than 200 - e.g. a 404 or 500 error. This means you can use datasette --get / to run tests against a Datasette application in a continuous integration environment such as GitHub Actions. 1  
11 datasette serve --help Running datasette downloads.db executes the default serve sub-command, and is equivalent to running datasette serve downloads.db . The full list of options to that command is shown below. $ datasette serve --help Usage: datasette serve [OPTIONS] [FILES]... Serve up specified SQLite database files with a web UI Options: -i, --immutable PATH Database files to open in immutable mode -h, --host TEXT Host for server.

12 Full-text search SQLite includes a powerful mechanism for enabling full-text search against SQLite records. Datasette can detect if a table has had full-text search configured for it in the underlying database and display a search interface for filtering that table. Datasette automatically detects which tables have been configured for full-text search. 1  
13 The table page and table view API Table views that support full-text search can be queried using the ?_search=TERMS query string parameter. This will run the search against content from all of the columns that have been included in the index. Try this example: fara.datasettes.com/fara/FARA_All_ShortForms?_search=manafort SQLite full-text search supports wildcards. This means you can easily implement prefix auto-complete by including an asterisk at the end of the search term - for example: /dbname/tablename/?_search=rob* This will return all records containing at least one word that starts with the letters rob . You can also run searches against just the content of a specific named column by using _search_COLNAME=TERMS - for example, this would search for just rows where the name column in the FTS index mentions Sarah : /dbname/tablename/?_search_name=Sarah 1  
14 Advanced SQLite search queries SQLite full-text search includes support for a variety of advanced queries , including AND , OR , NOT and NEAR . By default Datasette disables these features to ensure they do not cause any confusion for users who are not aware of them. You can disable this escaping and use the advanced queries by adding ?_searchmode=raw to the table page query string. 1  
15 Configuring full-text search for a table or view If a table has a corresponding FTS table set up using the content= argument to CREATE VIRTUAL TABLE shown above, Datasette will detect it automatically and add a search interface to the table page for that table. You can also manually configure which table should be used for full-text search using query string parameters or Metadata . You can set the associated FTS table for a specific table and you can also set one for a view - if you do that, the page for that SQL view will offer a search option. Use ?_fts_table=x to over-ride the FTS table for a specific page. If the primary key was something other than rowid you can use ?_fts_pk=col to set that as well. This is particularly useful for views, for example: https://latest.datasette.io/fixtures/searchable_view?_fts_table=searchable_fts&_fts_pk=pk The fts_table metadata property can be used to specify an associated FTS table. If the primary key column in your table which was used to populate the FTS table is something other than rowid , you can specify the column to use with the fts_pk property. Here is an example which enables full-text search for a display_ads view which is defined against the ads table and hence needs to run FTS against the ads_fts table, using the id as the primary key: { "databases": { "russian-ads": { "tables": { "display_ads": { "fts_table": "ads_fts", "fts_pk": "id" } } } } } 1  
16 Searches using custom SQL You can include full-text search results in custom SQL queries. The general pattern with SQLite search is to run the search as a sub-select that returns rowid values, then include those rowids in another part of the query. You can see the syntax for a basic search by running that search on a table page and then clicking "View and edit SQL" to see the underlying SQL. For example, consider this search for manafort is the US FARA database : /fara/FARA_All_ShortForms?_search=manafort If you click View and edit SQL you'll see that the underlying SQL looks like this: select rowid, Short_Form_Termination_Date, Short_Form_Date, Short_Form_Last_Name, Short_Form_First_Name, Registration_Number, Registration_Date, Registrant_Name, Address_1, Address_2, City, State, Zip from FARA_All_ShortForms where rowid in ( select rowid from FARA_All_ShortForms_fts where FARA_All_ShortForms_fts match escape_fts(:search) ) order by rowid limit 101 1  
17 Enabling full-text search for a SQLite table Datasette takes advantage of the external content mechanism in SQLite, which allows a full-text search virtual table to be associated with the contents of another SQLite table. To set up full-text search for a table, you need to do two things: Create a new FTS virtual table associated with your table Populate that FTS table with the data that you would like to be able to run searches against 1  
18 Configuring FTS using sqlite-utils sqlite-utils is a CLI utility and Python library for manipulating SQLite databases. You can use it from Python code to configure FTS search, or you can achieve the same goal using the accompanying command-line tool . Here's how to use sqlite-utils to enable full-text search for an items table across the name and description columns: $ sqlite-utils enable-fts mydatabase.db items name description 1  
19 Configuring FTS using csvs-to-sqlite If your data starts out in CSV files, you can use Datasette's companion tool csvs-to-sqlite to convert that file into a SQLite database and enable full-text search on specific columns. For a file called items.csv where you want full-text search to operate against the name and description columns you would run the following: $ csvs-to-sqlite items.csv items.db -f name -f description 1  
20 Configuring FTS by hand We recommend using sqlite-utils , but if you want to hand-roll a SQLite full-text search table you can do so using the following SQL. To enable full-text search for a table called items that works against the name and description columns, you would run this SQL to create a new items_fts FTS virtual table: CREATE VIRTUAL TABLE "items_fts" USING FTS4 ( name, description, content="items" ); This creates a set of tables to power full-text search against items . The new items_fts table will be detected by Datasette as the fts_table for the items table. Creating the table is not enough: you also need to populate it with a copy of the data that you wish to make searchable. You can do that using the following SQL: INSERT INTO "items_fts" (rowid, name, description) SELECT rowid, name, description FROM items; If your table has columns that are foreign key references to other tables you can include that data in your full-text search index using a join. Imagine the items table has a foreign key column called category_id which refers to a categories table - you could create a full-text search table like this: CREATE VIRTUAL TABLE "items_fts" USING FTS4 ( name, description, category_name, content="items" ); And then populate it like this: INSERT INTO "items_fts" (rowid, name, description, category_name) SELECT items.rowid, items.name, items.description, categories.name FROM items JOIN categories ON items.category_id=categories.id; You can use this technique to populate the full-text search index from any combination of tables and joins that makes sense for your project. 1  
21 FTS versions There are three different versions of the SQLite FTS module: FTS3, FTS4 and FTS5. You can tell which versions are supported by your instance of Datasette by checking the /-/versions page. FTS5 is the most advanced module but may not be available in the SQLite version that is bundled with your Python installation. Most importantly, FTS5 is the only version that has the ability to order by search relevance without needing extra code. If you can't be sure that FTS5 will be available, you should use FTS4. 1  
22 Changelog   1  
23 0.55 (2021-02-18) Support for cross-database SQL queries and built-in support for serving via HTTPS. The new --crossdb command-line option causes Datasette to attach up to ten database files to the same /_memory database connection. This enables cross-database SQL queries, including the ability to use joins and unions to combine data from tables that exist in different database files. See Cross-database queries for details. ( #283 ) --ssl-keyfile and --ssl-certfile options can be used to specify a TLS certificate, allowing Datasette to serve traffic over https:// without needing to run it behind a separate proxy. ( #1221 ) The /:memory: page has been renamed (and redirected) to /_memory for consistency with the new /_internal database introduced in Datasette 0.54. ( #1205 ) Added plugin testing documentation on Using pdb for errors thrown inside Datasette . ( #1207 ) The official Datasette Docker image now uses Python 3.7.10, applying the latest security fix for that Python version. ( #1235 ) 1  
24 0.54.1 (2021-02-02) Fixed a bug where ?_search= and ?_sort= parameters were incorrectly duplicated when the filter form on the table page was re-submitted. ( #1214 ) 1  
25 0.54 (2021-01-25) The two big new features in this release are the _internal SQLite in-memory database storing details of all connected databases and tables, and support for JavaScript modules in plugins and additional scripts. For additional commentary on this release, see Datasette 0.54, the annotated release notes . 1  
26 The _internal database As part of ongoing work to help Datasette handle much larger numbers of connected databases and tables (see Datasette Library ) Datasette now maintains an in-memory SQLite database with details of all of the attached databases, tables, columns, indexes and foreign keys. ( #1150 ) This will support future improvements such as a searchable, paginated homepage of all available tables. You can explore an example of this database by signing in as root to the latest.datasette.io demo instance and then navigating to latest.datasette.io/_internal . Plugins can use these tables to introspect attached data in an efficient way. Plugin authors should note that this is not yet considered a stable interface, so any plugins that use this may need to make changes prior to Datasette 1.0 if the _internal table schemas change. 1  
27 Named in-memory database support As part of the work building the _internal database, Datasette now supports named in-memory databases that can be shared across multiple connections. This allows plugins to create in-memory databases which will persist data for the lifetime of the Datasette server process. ( #1151 ) The new memory_name= parameter to the Database class can be used to create named, shared in-memory databases. 1  
28 JavaScript modules JavaScript modules were introduced in ECMAScript 2015 and provide native browser support for the import and export keywords. To use modules, JavaScript needs to be included in <script> tags with a type="module" attribute. Datasette now has the ability to output <script type="module"> in places where you may wish to take advantage of modules. The extra_js_urls option described in Custom CSS and JavaScript can now be used with modules, and module support is also available for the extra_body_script() plugin hook. ( #1186 , #1187 ) datasette-leaflet-freedraw is the first example of a Datasette plugin that takes advantage of the new support for JavaScript modules. See Drawing shapes on a map to query a SpatiaLite database for more on this plugin. 1  
29 Code formatting with Black and Prettier Datasette adopted Black for opinionated Python code formatting in June 2019. Datasette now also embraces Prettier for JavaScript formatting, which like Black is enforced by tests in continuous integration. Instructions for using these two tools can be found in the new section on Code formatting in the contributors documentation. ( #1167 ) 1  
30 Other changes Datasette can now open multiple database files with the same name, e.g. if you run datasette path/to/one.db path/to/other/one.db . ( #509 ) datasette publish cloudrun now sets force_https_urls for every deployment, fixing some incorrect http:// links. ( #1178 ) Fixed a bug in the example nginx configuration in Running Datasette behind a proxy . ( #1091 ) The Datasette Ecosystem documentation page has been reduced in size in favour of the datasette.io tools and plugins directories. ( #1182 ) The request object now provides a request.full_path property, which returns the path including any query string. ( #1184 ) Better error message for disallowed PRAGMA clauses in SQL queries. ( #1185 ) datasette publish heroku now deploys using python-3.8.7 . New plugin testing documentation on Testing outbound HTTP calls with pytest-httpx . ( #1198 ) All ?_* query string parameters passed to the table page are now persisted in hidden form fields, so parameters such as ?_size=10 will be correctly passed to the next page when query filters are changed. ( #1194 ) Fixed a bug loading a database file called test-database (1).sqlite . ( #1181 ) 1  
31 0.53 (2020-12-10) Datasette has an official project website now, at https://datasette.io/ . This release mainly updates the documentation to reflect the new site. New ?column__arraynotcontains= table filter. ( #1132 ) datasette serve has a new --create option, which will create blank database files if they do not already exist rather than exiting with an error. ( #1135 ) New ?_header=off option for CSV export which omits the CSV header row, documented here . ( #1133 ) "Powered by Datasette" link in the footer now links to https://datasette.io/ . ( #1138 ) Project news no longer lives in the README - it can now be found at https://datasette.io/news . ( #1137 ) 1  
32 0.52.5 (2020-12-09) Fix for error caused by combining the _searchmode=raw and ?_search_COLUMN parameters. ( #1134 ) 1  
33 0.52.4 (2020-12-05) Show pysqlite3 version on /-/versions , if installed. ( #1125 ) Errors output by Datasette (e.g. for invalid SQL queries) now go to stderr , not stdout . ( #1131 ) Fix for a startup error on windows caused by unnecessary from os import EX_CANTCREAT - thanks, Abdussamet Koçak. ( #1094 ) 1  
34 0.52.3 (2020-12-03) Fixed bug where static assets would 404 for Datasette installed on ARM Amazon Linux. ( #1124 ) 1  
35 0.52.2 (2020-12-02) Generated columns from SQLite 3.31.0 or higher are now correctly displayed. ( #1116 ) Error message if you attempt to open a SpatiaLite database now suggests using --load-extension=spatialite if it detects that the extension is available in a common location. ( #1115 ) OPTIONS requests against the /database page no longer raise a 500 error. ( #1100 ) Databases larger than 32MB that are published to Cloud Run can now be downloaded. ( #749 ) Fix for misaligned cog icon on table and database pages. Thanks, Abdussamet Koçak. ( #1121 ) 1  
36 0.52.1 (2020-11-29) Documentation on Testing plugins now recommends using datasette.client . ( #1102 ) Fix bug where compound foreign keys produced broken links. ( #1098 ) datasette --load-module=spatialite now also checks for /usr/local/lib/mod_spatialite.so . Thanks, Dan Peterson. ( #1114 ) 1  
37 0.52 (2020-11-28) This release includes a number of changes relating to an internal rebranding effort: Datasette's configuration mechanism (things like datasette --config default_page_size:10 ) has been renamed to settings . New --setting default_page_size 10 option as a replacement for --config default_page_size:10 (note the lack of a colon). The --config option is deprecated but will continue working until Datasette 1.0. ( #992 ) The /-/config introspection page is now /-/settings , and the previous page redirects to the new one. ( #1103 ) The config.json file in Configuration directory mode is now called settings.json . ( #1104 ) The undocumented datasette.config() internal method has been replaced by a documented .setting(key) method. ( #1107 ) Also in this release: New plugin hook: database_actions(datasette, actor, database) , which adds menu items to a new cog menu shown at the top of the database page. ( #1077 ) datasette publish cloudrun has a new --apt-get-install option that can be used to install additional Ubuntu packages as part of the deployment. This is useful for deploying the new datasette-ripgrep plugin . ( #1110 ) Swept the documentation to remove words that minimize involved difficulty. ( #1089 ) And some bug fixes: Foreign keys linking to rows with blank label columns now display as a hyphen, allowing those links to be clicked. ( #1086 ) Fixed bug where row pages could sometimes 500 if the un… 1  
38 0.51.1 (2020-10-31) Improvements to the new Binary data documentation page. 1  
39 0.51 (2020-10-31) A new visual design, plugin hooks for adding navigation options, better handling of binary data, URL building utility methods and better support for running Datasette behind a proxy. 1  
40 New visual design Datasette is no longer white and grey with blue and purple links! Natalie Downe has been working on a visual refresh, the first iteration of which is included in this release. ( #1056 ) 1  
41 Plugins can now add links within Datasette A number of existing Datasette plugins add new pages to the Datasette interface, providig tools for things like uploading CSVs , editing table schemas or configuring full-text search . Plugins like this can now link to themselves from other parts of Datasette interface. The menu_links(datasette, actor) hook ( #1064 ) lets plugins add links to Datasette's new top-right application menu, and the table_actions(datasette, actor, database, table) hook ( #1066 ) adds links to a new "table actions" menu on the table page. The demo at latest.datasette.io now includes some example plugins. To see the new table actions menu first sign into that demo as root and then visit the facetable table to see the new cog icon menu at the top of the page. 1  
42 Binary data SQLite tables can contain binary data in BLOB columns. Datasette now provides links for users to download this data directly from Datasette, and uses those links to make binary data available from CSV exports. See Binary data for more details. ( #1036 and #1034 ). 1  
43 URL building The new datasette.urls family of methods can be used to generate URLs to key pages within the Datasette interface, both within custom templates and Datasette plugins. See Building URLs within plugins for more details. ( #904 ) 1  
44 Running Datasette behind a proxy The base_url configuration option is designed to help run Datasette on a specific path behind a proxy - for example if you want to run an instance of Datasette at /my-datasette/ within your existing site's URL hierarchy, proxied behind nginx or Apache. Support for this configuration option has been greatly improved ( #1023 ), and guidelines for using it are now available in a new documentation section on Running Datasette behind a proxy . ( #1027 ) 1  
45 Smaller changes Wide tables shown within Datasette now scroll horizontally ( #998 ). This is achieved using a new <div class="table-wrapper"> element which may impact the implementation of some plugins (for example this change to datasette-cluster-map ). New debug-menu permission. ( #1068 ) Removed --debug option, which didn't do anything. ( #814 ) Link: HTTP header pagination. ( #1014 ) x button for clearing filters. ( #1016 ) Edit SQL button on canned queries, ( #1019 ) --load-extension=spatialite shortcut. ( #1028 ) scale-in animation for column action menu. ( #1039 ) Option to pass a list of templates to .render_template() is now documented. ( #1045 ) New datasette.urls.static_plugins() method. ( #1033 ) datasette -o option now opens the most relevant page. ( #976 ) datasette --cors option now enables access to /database.db downloads. ( #1057 ) Database file downloads now implement cascading permissions, so you can download a database if you have view-database-download permission even if you do not have permission to access the Datasette instance. ( #1058 ) New documentation on Designing URLs for your plugin . (… 1  
46 0.50.2 (2020-10-09) Fixed another bug introduced in 0.50 where column header links on the table page were broken. ( #1011 ) 1  
47 0.50.1 (2020-10-09) Fixed a bug introduced in 0.50 where the export as JSON/CSV links on the table, row and query pages were broken. ( #1010 ) 1  
48 0.50 (2020-10-09) The key new feature in this release is the column actions menu on the table page ( #891 ). This can be used to sort a column in ascending or descending order, facet data by that column or filter the table to just rows that have a value for that column. Plugin authors can use the new datasette.client object to make internal HTTP requests from their plugins, allowing them to make use of Datasette's JSON API. ( #943 ) New Deploying Datasette documentation with guides for deploying Datasette on a Linux server using systemd or to hosting providers that support buildpacks . ( #514 , #997 ) Other improvements in this release: Publishing to Google Cloud Run documentation now covers Google Cloud SDK options. Thanks, Geoffrey Hing. ( #995 ) New datasette -o option which opens your browser as soon as Datasette starts up. ( #970 ) Datasette now sets sqlite3.enable_callback_tracebacks(True) so that errors in custom SQL functions will display tracebacks. ( #891 ) Fixed two rendering bugs with column headers in portrait mobile view. ( #978 , #980 ) New db.table_column_details(table) introspection method for retrieving full details of the columns in a specific table, see Database introspection . Fixed a routing bug with custom page wildcard templates. ( #996 ) datasette publish heroku now deploys using Python 3.8.6. New datasette publish heroku --tar= option. ( #969 ) OPTIONS requests against HTML pages no longer return a 500 error. ( #1001 ) … 1

54 0.47.1 (2020-08-11) Fixed a bug where the sdist distribution of Datasette was not correctly including the template files. ( #930 ) 1  
55 0.47 (2020-08-11) Datasette now has a GitHub discussions forum for conversations about the project that go beyond just bug reports and issues. Datasette can now be installed on macOS using Homebrew! Run brew install simonw/datasette/datasette . See Using Homebrew . ( #335 ) Two new commands: datasette install name-of-plugin and datasette uninstall name-of-plugin . These are equivalent to pip install and pip uninstall but automatically run in the same virtual environment as Datasette, so users don't have to figure out where that virtual environment is - useful for installations created using Homebrew or pipx . See Installing plugins . ( #925 ) A new command-line option, datasette --get , accepts a path to a URL within the Datasette instance. It will run that request through Datasette (without starting a web server) and print out the repsonse. See datasette --get for an example. ( #926 ) 1  
56 0.46 (2020-08-09) This release contains a security fix related to authenticated writable canned queries. If you are using this feature you should upgrade as soon as possible. Security fix: CSRF tokens were incorrectly included in read-only canned query forms, which could allow them to be leaked to a sophisticated attacker. See issue 918 for details. Datasette now supports GraphQL via the new datasette-graphql plugin - see GraphQL in Datasette with the new datasette-graphql plugin . Principle git branch has been renamed from master to main . ( #849 ) New debugging tool: /-/allow-debug tool ( demo here ) helps test allow blocks against actors, as described in Defining permissions with "allow" blocks .

( #897 ) Database file downloads now include a content-length HTTP header, enabling download progress bars. ( #905 ) File downloads now also correctly set the suggested file name using a content-disposition HTTP header. ( #909 ) tests are now excluded from the Datasette package properly - thanks, abeyerpath. ( #456 ) The Datasette package published to PyPI now include… 1  
57 0.45 (2020-07-01) See also Datasette 0.45: The annotated release notes . Magic parameters for canned queries, a log out feature, improved plugin documentation and four new plugin hooks. 1  
58 Magic parameters for canned queries Canned queries now support Magic parameters , which can be used to insert or select automatically generated values. For example: insert into logs (user_id, timestamp) values (:_actor_id, :_now_datetime_utc) This inserts the currently authenticated actor ID and the current datetime. ( #842 ) 1  
59 Log out The ds_actor cookie can be used by plugins (or by Datasette's --root mechanism ) to authenticate users. The new /-/logout page provides a way to clear that cookie. A "Log out" button now shows in the global navigation provided the user is authenticated using the ds_actor cookie. ( #840 ) 1  
60 Better plugin documentation The plugin documentation has been re-arranged into four sections, including a brand new section on testing plugins. ( #687 ) Plugins introduces Datasette's plugin system and describes how to install and configure plugins. Writing plugins describes how to author plugins, from one-off single file plugins to packaged plugins that can be published to PyPI. It also describes how to start a plugin using the new datasette-plugin cookiecutter template. Plugin hooks is a full list of detailed documentation for every Datasette plugin hook. Testing plugins describes how to write tests for Datasette plugins, using pytest and HTTPX . 1  
61 New plugin hooks register_magic_parameters(datasette) can be used to define new types of magic canned query parameters. startup(datasette) can run custom code when Datasette first starts up. datasette-init is a new plugin that uses this hook to create database tables and views on startup if they have not yet been created. ( #834 ) canned_queries(datasette, database, actor) lets plugins provide additional canned queries beyond those defined in Datasette's metadata. See datasette-saved-queries for an example of this hook in action. ( #852 ) forbidden(datasette, request, message) is a hook for customizing how Datasette responds to 403 forbidden errors. ( #812 ) 1  
62 Smaller changes Cascading view permissons - so if a user has view-table they can view the table page even if they do not have view-database or view-instance . ( #832 ) CSRF protection no longer applies to Authentication: Bearer token requests or requests without cookies. ( #835 ) datasette.add_message() now works inside plugins. ( #864 ) Workaround for "Too many open files" error in test runs. ( #846 ) Respect existing scope["actor"] if already set by ASGI middleware. ( #854 ) New process for shipping Alpha and beta releases . ( #807 ) {{ csrftoken() }} now works when plugins render a template using datasette.render_template(..., request=request) . ( #863 ) Datasette now creates a single Request object and uses it throughout the lifetime of the current HTTP request. ( #870 ) 1  
63 0.44 (2020-06-11) See also Datasette 0.44: The annotated release notes . Authentication and permissions, writable canned queries, flash messages, new plugin hooks and more. 1  
64 Authentication Prior to this release the Datasette ecosystem has treated authentication as exclusively the realm of plugins, most notably through datasette-auth-github . 0.44 introduces Authentication and permissions as core Datasette concepts ( #699 ). This enables different plugins to share responsibility for authenticating requests - you might have one plugin that handles user accounts and another one that allows automated access via API keys, for example. You'll need to install plugins if you want full user accounts, but default Datasette can now authenticate a single root user with the new --root command-line option, which outputs a one-time use URL to authenticate as a root actor ( #784 ): $ datasette fixtures.db --root http://127.0.0.1:8001/-/auth-token?token=5b632f8cd44b868df625f5a6e2185d88eea5b22237fd3cc8773f107cc4fd6477 INFO: Started server process [14973] INFO: Waiting for application startup. INFO: Application startup complete. INFO: Uvicorn running on http://127.0.0.1:8001 (Press CTRL+C to quit) Plugins can implement new ways of authenticating users using the new actor_from_request(datasette, request) hook. 1  
65 Permissions Datasette also now has a built-in concept of Permissions . The permissions system answers the following question: Is this actor allowed to perform this action , optionally against this particular resource ? You can use the new "allow" block syntax in metadata.json (or metadata.yaml ) to set required permissions at the instance, database, table or canned query level. For example, to restrict access to the fixtures.db database to the "root" user: { "databases": { "fixtures": { "allow": { "id" "root" } } } } See Defining permissions with "allow" blocks for more details. Plugins can implement their own custom permission checks using the new permission_allowed(datasette, actor, action, resource) hook. A new debug page at /-/permissions shows recent permission checks, to help administrators and plugin authors understand exactly what checks are being performed. This tool defaults to only being available to the root user, but can be exposed to other users by plugins that respond to the permissions-debug permission. ( #788 ) 1  
66 Writable canned queries Datasette's Canned queries feature lets you define SQL queries in metadata.json which can then be executed by users visiting a specific URL. https://latest.datasette.io/fixtures/neighborhood_search for example. Canned queries were previously restricted to SELECT , but Datasette 0.44 introduces the ability for canned queries to execute INSERT or UPDATE queries as well, using the new "write": true property ( #800 ): { "databases": { "dogs": { "queries": { "add_name": { "sql": "INSERT INTO names (name) VALUES (:name)", "write": true } } } } } See Writable canned queries for more details. 1  
67 Flash messages Writable canned queries needed a mechanism to let the user know that the query has been successfully executed. The new flash messaging system ( #790 ) allows messages to persist in signed cookies which are then displayed to the user on the next page that they visit. Plugins can use this mechanism to display their own messages, see .add_message(request, message, message_type=datasette.INFO) for details. You can try out the new messages using the /-/messages debug tool, for example at https://latest.datasette.io/-/messages 1  
68 Signed values and secrets Both flash messages and user authentication needed a way to sign values and set signed cookies. Two new methods are now available for plugins to take advantage of this mechanism: .sign(value, namespace="default") and .unsign(value, namespace="default") . Datasette will generate a secret automatically when it starts up, but to avoid resetting the secret (and hence invalidating any cookies) every time the server restarts you should set your own secret. You can pass a secret to Datasette using the new --secret option or with a DATASETTE_SECRET environment variable. See Configuring the secret for more details. You can also set a secret when you deploy Datasette using datasette publish or datasette package - see Using secrets with datasette publish . Plugins can now sign values and verify their signatures using the datasette.sign() and datasette.unsign() methods. 1  
69 CSRF protection Since writable canned queries are built using POST forms, Datasette now ships with CSRF protection ( #798 ). This applies automatically to any POST request, which means plugins need to include a csrftoken in any POST forms that they render. They can do that like so: <input type="hidden" name="csrftoken" value="{{ csrftoken() }}"> 1  
70 Cookie methods Plugins can now use the new response.set_cookie() method to set cookies. A new request.cookies method on the :ref:internals_request` can be used to read incoming cookies. 1  
71 register_routes() plugin hooks Plugins can now register new views and routes via the register_routes() plugin hook ( #819 ). View functions can be defined that accept any of the current datasette object, the current request , or the ASGI scope , send and receive objects. 1  
72 Smaller changes New internals documentation for Request object and Response class . ( #706 ) request.url now respects the force_https_urls config setting. closes ( #781 ) request.args.getlist() returns [] if missing. Removed request.raw_args entirely. ( #774 ) New datasette.get_database() method. Added _ prefix to many private, undocumented methods of the Datasette class. ( #576 ) Removed the db.get_outbound_foreign_keys() method which duplicated the behaviour of db.foreign_keys_for_table() . New await datasette.permission_allowed() method. /-/actor debugging endpoint for viewing the currently authenticated actor. New request.cookies property. /-/plugins endpoint now shows a list of hooks implemented by each plugin, e.g. https://latest.datasette.io/-/plugins?all=1 request.post_vars() method no longer discards empty values. New "params" canned query key for explicitly setting named parameters, see Canned query parameters . ( #797 ) request.args is now a MultiParams object. Fixed a bug with the datasette plugins command. ( #802 ) Nicer pa… 1  
73 The road to Datasette 1.0 I've assembled a milestone for Datasette 1.0 . The focus of the 1.0 release will be the following: Signify confidence in the quality/stability of Datasette Give plugin authors confidence that their plugins will work for the whole 1.x release cycle Provide the same confidence to developers building against Datasette JSON APIs If you have thoughts about what you would like to see for Datasette 1.0 you can join the conversation on issue #519 . 1  
74 0.43 (2020-05-28) The main focus of this release is a major upgrade to the register_output_renderer(datasette) plugin hook, which allows plugins to provide new output formats for Datasette such as datasette-atom and datasette-ics . Redesign of register_output_renderer(datasette) to provide more context to the render callback and support an optional "can_render" callback that controls if a suggested link to the output format is provided. ( #581 , #770 ) Visually distinguish float and integer columns - useful for figuring out why order-by-column might be returning unexpected results. ( #729 ) The Request object , which is passed to several plugin hooks, is now documented. ( #706 ) New metadata.json option for setting a custom default page size for specific tables and views, see Setting a custom page size . ( #751 ) Canned queries can now be configured with a default URL fragment hash, useful when working with plugins such as datasette-vega , see Setting a default fragment . ( #706 ) Fixed a bug in datasette publish when running on operating systems where the /tmp directory lives in a different volume, using a backport of the Python 3.8 shutil.copytree() function. ( #744 ) Every plugin hook is now covered by the unit tests, and a new unit test checks that each plugin hook has at least one corresponding test. ( #771 , #773 ) 1  
75 0.42 (2020-05-08) A small release which provides improved internal methods for use in plugins, along with documentation. See #685 . Added documentation for db.execute() , see await db.execute(sql, ...) . Renamed db.execute_against_connection_in_thread() to db.execute_fn() and made it a documented method, see await db.execute_fn(fn) . New results.first() and results.single_value() methods, plus documentation for the Results class - see Results . 1  
76 0.41 (2020-05-06) You can now create custom pages within your Datasette instance using a custom template file. For example, adding a template file called templates/pages/about.html will result in a new page being served at /about on your instance. See the custom pages documentation for full details, including how to return custom HTTP headers, redirects and status codes. ( #648 ) Configuration directory mode ( #731 ) allows you to define a custom Datasette instance as a directory. So instead of running the following: $ datasette one.db two.db \ --metadata=metadata.json \ --template-dir=templates/ \ --plugins-dir=plugins \ --static css:css You can instead arrange your files in a single directory called my-project and run this: $ datasette my-project/ Also in this release: New NOT LIKE table filter: ?colname__notlike=expression . ( #750 ) Datasette now has a pattern portfolio at /-/patterns - e.g. https://latest.datasette.io/-/patterns . This is a page that shows every Datasette user interface component in one place, to aid core development and people building custom CSS themes. ( #151 ) SQLite PRAGMA functions such as pragma_table_info(tablename) are now allowed in Datasette SQL queries. ( #761 ) Datasette pages now consistently return a content-type of text/html; charset=utf-8" . ( #752 ) Datasette now handles an ASGI raw_path value of None , which should allow compatibilty with the Mangum adapter for running ASGI apps on AWS Lambda. Thanks, Colin Dellow. ( #719 ) Installation documentation now covers how to Using pipx . ( #756 ) … 1  
77 0.40 (2020-04-21) Datasette Metadata can now be provided as a YAML file as an optional alternative to JSON. See Using YAML for metadata . ( #713 ) Removed support for datasette publish now , which used the the now-retired Zeit Now v1 hosting platform. A new plugin, datasette-publish-now , can be installed to publish data to Zeit ( now Vercel ) Now v2. ( #710 ) Fixed a bug where the extra_template_vars(request, view_name) plugin hook was not receiving the correct view_name . ( #716 ) Variables added to the template context by the extra_template_vars() plugin hook are now shown in the ?_context=1 debugging mode (see template_debug ). ( #693 ) Fixed a bug where the "templates considered" HTML comment was no longer being displayed. ( #689 ) Fixed a datasette publish bug where --plugin-secret would over-ride plugin configuration in the provided metadata.json file. ( #724 ) Added a new CSS class for customizing the canned query page. ( #727 ) 1  
78 0.39 (2020-03-24) New base_url configuration setting for serving up the correct links while running Datasette under a different URL prefix. ( #394 ) New metadata settings "sort" and "sort_desc" for setting the default sort order for a table. See Setting a default sort order . ( #702 ) Sort direction arrow now displays by default on the primary key. This means you only have to click once (not twice) to sort in reverse order. ( #677 ) New await Request(scope, receive).post_vars() method for accessing POST form variables. ( #700 ) Plugin hooks documentation now links to example uses of each plugin. ( #709 ) 1  
79 0.38 (2020-03-08) The Docker build of Datasette now uses SQLite 3.31.1, upgraded from 3.26. ( #695 ) datasette publish cloudrun now accepts an optional --memory=2Gi flag for setting the Cloud Run allocated memory to a value other than the default (256Mi). ( #694 ) Fixed bug where templates that shipped with plugins were sometimes not being correctly loaded. ( #697 ) 1  
80 0.37.1 (2020-03-02) Don't attempt to count table rows to display on the index page for databases > 100MB. ( #688 ) Print exceptions if they occur in the write thread rather than silently swallowing them. Handle the possibility of scope["path"] being a string rather than bytes Better documentation for the extra_template_vars(template, database, table, columns, view_name, request, datasette) plugin hook. 1  
81 0.37 (2020-02-25) Plugins now have a supported mechanism for writing to a database, using the new .execute_write() and .execute_write_fn() methods. Documentation . ( #682 ) Immutable databases that have had their rows counted using the inspect command now use the calculated count more effectively - thanks, Kevin Keogh. ( #666 ) --reload no longer restarts the server if a database file is modified, unless that database was opened immutable mode with -i . ( #494 ) New ?_searchmode=raw option turns off escaping for FTS queries in ?_search= allowing full use of SQLite's FTS5 query syntax . ( #676 ) 1  
82 0.36 (2020-02-21) The datasette object passed to plugins now has API documentation: Datasette class . ( #576 ) New methods on datasette : .add_database() and .remove_database() - documentation . ( #671 ) prepare_connection() plugin hook now takes optional datasette and database arguments - prepare_connection(conn, database, datasette) . ( #678 ) Added three new plugins and one new conversion tool to the The Datasette Ecosystem . 1  
83 0.35 (2020-02-04) Added five new plugins and one new conversion tool to the The Datasette Ecosystem . The Datasette class has a new render_template() method which can be used by plugins to render templates using Datasette's pre-configured Jinja templating library. You can now execute SQL queries that start with a -- comment - thanks, Jay Graves ( #653 ) 1  
84 0.34 (2020-01-29) _search= queries are now correctly escaped using a new escape_fts() custom SQL function. This means you can now run searches for strings like park. without seeing errors. ( #651 ) Google Cloud Run is no longer in beta, so datasette publish cloudrun has been updated to work even if the user has not installed the gcloud beta components package. Thanks, Katie McLaughlin ( #660 ) datasette package now accepts a --port option for specifying which port the resulting Docker container should listen on. ( #661 ) 1  
85 0.33 (2019-12-22) rowid is now included in dropdown menus for filtering tables ( #636 ) Columns are now only suggested for faceting if they have at least one value with more than one record ( #638 ) Queries with no results now display "0 results" ( #637 ) Improved documentation for the --static option ( #641 ) asyncio task information is now included on the /-/threads debug page Bumped Uvicorn dependency 0.11 You can now use --port 0 to listen on an available port New template_debug setting for debugging templates, e.g. https://latest.datasette.io/fixtures/roadside_attractions?_context=1 ( #654 ) 1  
86 0.32 (2019-11-14) Datasette now renders templates using Jinja async mode . This means plugins can provide custom template functions that perform asynchronous actions, for example the new datasette-template-sql plugin which allows custom templates to directly execute SQL queries and render their results. ( #628 ) 1  
87 0.31.2 (2019-11-13) Fixed a bug where datasette publish heroku applications failed to start ( #633 ) Fix for datasette publish with just --source_url - thanks, Stanley Zheng ( #572 ) Deployments to Heroku now use Python 3.8.0 ( #632 ) 1  
88 0.31.1 (2019-11-12) Deployments created using datasette publish now use python:3.8 base Docker image ( #629 ) 1  
89 0.31 (2019-11-11) This version adds compatibility with Python 3.8 and breaks compatibility with Python 3.5. If you are still running Python 3.5 you should stick with 0.30.2 , which you can install like this: pip install datasette==0.30.2 Format SQL button now works with read-only SQL queries - thanks, Tobias Kunze ( #602 ) New ?column__notin=x,y,z filter for table views ( #614 ) Table view now uses select col1, col2, col3 instead of select * Database filenames can now contain spaces - thanks, Tobias Kunze ( #590 ) Removed obsolete ?_group_count=col feature ( #504 ) Improved user interface and documentation for datasette publish cloudrun ( #608 ) Tables with indexes now show the CREATE INDEX statements on the table page ( #618 ) Current version of uvicorn is now shown on /-/versions Python 3.8 is now supported! ( #622 ) Python 3.5 is no longer supported. 1  
90 0.30.2 (2019-11-02) /-/plugins page now uses distribution name e.g. datasette-cluster-map instead of the name of the underlying Python package ( datasette_cluster_map ) ( #606 ) Array faceting is now only suggested for columns that contain arrays of strings ( #562 ) Better documentation for the --host argument ( #574 ) Don't show None with a broken link for the label on a nullable foreign key ( #406 ) 1  
91 0.30.1 (2019-10-30) Fixed bug where ?_where= parameter was not persisted in hidden form fields ( #604 ) Fixed bug with .JSON representation of row pages - thanks, Chris Shaw ( #603 ) 1  
92 0.30 (2019-10-18) Added /-/threads debugging page Allow EXPLAIN WITH... ( #583 ) Button to format SQL - thanks, Tobias Kunze ( #136 ) Sort databases on homepage by argument order - thanks, Tobias Kunze ( #585 ) Display metadata footer on custom SQL queries - thanks, Tobias Kunze ( #589 ) Use --platform=managed for publish cloudrun ( #587 ) Fixed bug returning non-ASCII characters in CSV ( #584 ) Fix for /foo v.s. /foo-bar bug ( #601 ) 1  
93 0.29.3 (2019-09-02) Fixed implementation of CodeMirror on database page ( #560 ) Documentation typo fixes - thanks, Min ho Kim ( #561 ) Mechanism for detecting if a table has FTS enabled now works if the table name used alternative escaping mechanisms ( #570 ) - for compatibility with a recent change to sqlite-utils . 1  
94 0.29.2 (2019-07-13) Bumped Uvicorn to 0.8.4, fixing a bug where the query string was not included in the server logs. ( #559 ) Fixed bug where the navigation breadcrumbs were not displayed correctly on the page for a custom query. ( #558 ) Fixed bug where custom query names containing unicode characters caused errors. 1  
95 0.29.1 (2019-07-11) Fixed bug with static mounts using relative paths which could lead to traversal exploits ( #555 ) - thanks Abdussamet Kocak! Datasette can now be run as a module: python -m datasette ( #556 ) - thanks, Abdussamet Kocak! 1  
96 0.29 (2019-07-07) ASGI, new plugin hooks, facet by date and much, much more... 1  
97 ASGI ASGI is the Asynchronous Server Gateway Interface standard. I've been wanting to convert Datasette into an ASGI application for over a year - Port Datasette to ASGI #272 tracks thirteen months of intermittent development - but with Datasette 0.29 the change is finally released. This also means Datasette now runs on top of Uvicorn and no longer depends on Sanic . I wrote about the significance of this change in Porting Datasette to ASGI, and Turtles all the way down . The most exciting consequence of this change is that Datasette plugins can now take advantage of the ASGI standard. 1  
98 New plugin hook: asgi_wrapper The asgi_wrapper(datasette) plugin hook allows plugins to entirely wrap the Datasette ASGI application in their own ASGI middleware. ( #520 ) Two new plugins take advantage of this hook: datasette-auth-github adds a authentication layer: users will have to sign in using their GitHub account before they can view data or interact with Datasette. You can also use it to restrict access to specific GitHub users, or to members of specified GitHub organizations or teams . datasette-cors allows you to configure CORS headers for your Datasette instance. You can use this to enable JavaScript running on a whitelisted set of domains to make fetch() calls to the JSON API provided by your Datasette instance. 1  
99 New plugin hook: extra_template_vars The extra_template_vars(template, database, table, columns, view_name, request, datasette) plugin hook allows plugins to inject their own additional variables into the Datasette template context. This can be used in conjunction with custom templates to customize the Datasette interface. datasette-auth-github uses this hook to add custom HTML to the new top navigation bar (which is designed to be modified by plugins, see #540 ). 1  
100 Secret plugin configuration options Plugins like datasette-auth-github need a safe way to set secret configuration options. Since the default mechanism for configuring plugins exposes those settings in /-/metadata a new mechanism was needed. Secret configuration values describes how plugins can now specify that their settings should be read from a file or an environment variable: { "plugins": { "datasette-auth-github": { "client_secret": { "$env": "GITHUB_CLIENT_SECRET" } } } } These plugin secrets can be set directly using datasette publish . See Custom metadata and plugins for details. ( #538 and #543 ) 1
