authentication:authentication authentication authentication Authentication and permissions Datasette does not require authentication by default. Any visitor to a Datasette instance can explore the full data and execute read-only SQL queries. Datasette's plugin system can be used to add many different styles of authentication, such as user accounts, single sign-on or API keys. [] []
authentication:authentication-actor authentication authentication-actor Actors Through plugins, Datasette can support both authenticated users (with cookies) and authenticated API agents (via authentication tokens). The word "actor" is used to cover both of these cases. Every request to Datasette has an associated actor value, available in the code as request.actor . This can be None for unauthenticated requests, or a JSON compatible Python dictionary for authenticated users or API agents. The actor dictionary can be any shape - the design of that data structure is left up to the plugins. A useful convention is to include an "id" string, as demonstrated by the "root" actor below. Plugins can use the actor_from_request(datasette, request) hook to implement custom logic for authenticating an actor based on the incoming HTTP request. ["Authentication and permissions"] []
authentication:authentication-root authentication authentication-root Using the "root" actor Datasette currently leaves almost all forms of authentication to plugins - datasette-auth-github for example. The one exception is the "root" account, which you can sign into while using Datasette on your local machine. This provides access to a small number of debugging features. To sign in as root, start Datasette using the --root command-line option, like this: $ datasette --root http://127.0.0.1:8001/-/auth-token?token=786fc524e0199d70dc9a581d851f466244e114ca92f33aa3b42a139e9388daa7 INFO: Started server process [25801] INFO: Waiting for application startup. INFO: Application startup complete. INFO: Uvicorn running on http://127.0.0.1:8001 (Press CTRL+C to quit) The URL on the first line includes a one-use token which can be used to sign in as the "root" actor in your browser. Click on that link and then visit http://127.0.0.1:8001/-/actor to confirm that you are authenticated as an actor that looks like this: { "id": "root" } ["Authentication and permissions", "Actors"] [{"href": "https://github.com/simonw/datasette-auth-github", "label": "datasette-auth-github"}]
authentication:authentication-permissions authentication authentication-permissions Permissions Datasette has an extensive permissions system built-in, which can be further extended and customized by plugins. The key question the permissions system answers is this: Is this actor allowed to perform this action , optionally against this particular resource ? Actors are described above . An action is a string describing the action the actor would like to perform. A full list is provided below - examples include view-table and execute-sql . A resource is the item the actor wishes to interact with - for example a specific database or table. Some actions, such as permissions-debug , are not associated with a particular resource. Datasette's built-in view permissions ( view-database , view-table etc) default to allow - unless you configure additional permission rules unauthenticated users will be allowed to access content. Permissions with potentially harmful effects should default to deny . Plugin authors should account for this when designing new plugins - for example, the datasette-upload-csvs plugin defaults to deny so that installations don't accidentally allow unauthenticated users to create new tables by uploading a CSV file.

authentication:authentication-permissions-allow authentication authentication-permissions-allow Defining permissions with "allow" blocks The standard way to define permissions in Datasette is to use an "allow" block. This is a JSON document describing which actors are allowed to perform a permission. The most basic form of allow block is this ( allow demo , deny demo ): { "allow": { "id": "root" } } This will match any actors with an "id" property of "root" - for example, an actor that looks like this: { "id": "root", "name": "Root User" } An allow block can specify "deny all" using false ( demo ): { "allow": false } An "allow" of true allows all access ( demo ): { "allow": true } Allow keys can provide a list of values. These will match any actor that has any of those values ( allow demo , deny demo ): { "allow": { "id": ["simon", "cleopaws"] } } This will match any actor with an "id" of either "simon" or "cleopaws" . Actors can have properties that feature a list of values. These will be matched against the list of values in an allow block. Consider the following actor: { "id": "simon", "roles": ["staff", "developer"] } This allow block will provide access to any actor that has "developer" as one of their roles ( allow demo , deny demo ): { "allow": { "roles": ["developer"] } } Note that "roles" is not a concept that is baked into Datasette - it's a convention that plugins can choose to implement and act on. If you want to provide access to any actor with a value for a specific key, use "*" . For example, to match any logged-in user specify the following ( allow demo , deny demo ): { "allow": { "id": "*" } } You can specify that only unauthenticated actors (from anynomous HTTP requests) should be all… ["Authentication and permissions", "Permissions"] [{"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%22id%22%3A+%22root%22%7D&allow=%7B%0D%0A++++++++%22id%22%3A+%22root%22%0D%0A++++%7D", "label": "allow demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%22id%22%3A+%22trevor%22%7D&allow=%7B%0D%0A++++++++%22id%22%3A+%22root%22%0D%0A++++%7D", "label": "deny demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22root%22%0D%0A%7D&allow=false", "label": "demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22root%22%0D%0A%7D&allow=true", "label": "demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22cleopaws%22%0D%0A%7D&allow=%7B%0D%0A++++%22id%22%3A+%5B%0D%0A++++++++%22simon%22%2C%0D%0A++++++++%22cleopaws%22%0D%0A++++%5D%0D%0A%7D", "label": "allow demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22pancakes%22%0D%0A%7D&allow=%7B%0D%0A++++%22id%22%3A+%5B%0D%0A++++++++%22simon%22%2C%0D%0A++++++++%22cleopaws%22%0D%0A++++%5D%0D%0A%7D", "label": "deny demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22simon%22%2C%0D%0A++++%22roles%22%3A+%5B%0D%0A++++++++%22staff%22%2C%0D%0A++++++++%22developer%22%0D%0A++++%5D%0D%0A%7D&allow=%7B%0D%0A++++%22roles%22%3A+%5B%0D%0A++++++++%22developer%22%0D%0A++++%5D%0D%0A%7D", "label": "allow demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22cleopaws%22%2C%0D%0A++++%22roles%22%3A+%5B%22dog%22%5D%0D%0A%7D&allow=%7B%0D%0A++++%22roles%22%3A+%5B%0D%0A++++++++%22developer%22%0D%0A++++%5D%0D%0A%7D", "label": "deny demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22simon%22%0D%0A%7D&allow=%7B%0D%0A++++%22id%22%3A+%22*%22%0D%0A%7D", "label": "allow demo"}, {"href": "https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22bot%22%3A+%22readme-bot%22%0D%0A%7D&allow=%7B%0D%0A++++%22id%22%3A+%22*%22%0D%0A%7D", "label": "deny demo"…

authentication:authentication-permissions-metadata authentication authentication-permissions-metadata Configuring permissions in metadata.json You can limit who is allowed to view different parts of your Datasette instance using "allow" keys in your Metadata configuration. You can control the following: Access to the entire Datasette instance Access to specific databases Access to specific tables and views Access to specific Canned queries If a user cannot access a specific database, they will not be able to access tables, views or queries within that database. If a user cannot access the instance they will not be able to access any of the databases, tables, views or queries. ["Authentication and permissions"] []
authentication:authentication-permissions-instance authentication authentication-permissions-instance Controlling access to an instance Here's how to restrict access to your entire Datasette instance to just the "id": "root" user: { "title": "My private Datasette instance", "allow": { "id": "root" } } To deny access to all users, you can use "allow": false : { "title": "My entirely inaccessible instance", "allow": false } One reason to do this is if you are using a Datasette plugin - such as datasette-permissions-sql - to control permissions instead. ["Authentication and permissions", "Configuring permissions in metadata.json"] [{"href": "https://github.com/simonw/datasette-permissions-sql", "label": "datasette-permissions-sql"}]
authentication:authentication-permissions-database authentication authentication-permissions-database Controlling access to specific databases To limit access to a specific private.db database to just authenticated users, use the "allow" block like this: { "databases": { "private": { "allow": { "id": "*" } } } } ["Authentication and permissions", "Configuring permissions in metadata.json"] []
authentication:authentication-permissions-table authentication authentication-permissions-table Controlling access to specific tables and views To limit access to the users table in your bakery.db database: { "databases": { "bakery": { "tables": { "users": { "allow": { "id": "*" } } } } } } This works for SQL views as well - you can list their names in the "tables" block above in the same way as regular tables. Restricting access to tables and views in this way will NOT prevent users from querying them using arbitrary SQL queries, like this for example. If you are restricting access to specific tables you should also use the "allow_sql" block to prevent users from bypassing the limit with their own SQL queries - see Controlling the ability to execute arbitrary SQL . ["Authentication and permissions", "Configuring permissions in metadata.json"] [{"href": "https://latest.datasette.io/fixtures?sql=select+*+from+facetable", "label": "like this"}]
authentication:authentication-permissions-query authentication authentication-permissions-query Controlling access to specific canned queries Canned queries allow you to configure named SQL queries in your metadata.json that can be executed by users. These queries can be set up to both read and write to the database, so controlling who can execute them can be important. To limit access to the add_name canned query in your dogs.db database to just the root user : { "databases": { "dogs": { "queries": { "add_name": { "sql": "INSERT INTO names (name) VALUES (:name)", "write": true, "allow": { "id": ["root"] } } } } } } ["Authentication and permissions", "Configuring permissions in metadata.json"] []
authentication:authentication-permissions-execute-sql authentication authentication-permissions-execute-sql Controlling the ability to execute arbitrary SQL The "allow_sql" block can be used to control who is allowed to execute arbitrary SQL queries, both using the form on the database page e.g. https://latest.datasette.io/fixtures or by appending a ?_where= parameter to the table page as seen on https://latest.datasette.io/fixtures/facetable?_where=city_id=1 . To enable just the root user to execute SQL for all databases in your instance, use the following: { "allow_sql": { "id": "root" } } To limit this ability for just one specific database, use this: { "databases": { "mydatabase": { "allow_sql": { "id": "root" } } } } ["Authentication and permissions", "Configuring permissions in metadata.json"] [{"href": "https://latest.datasette.io/fixtures", "label": "https://latest.datasette.io/fixtures"}, {"href": "https://latest.datasette.io/fixtures/facetable?_where=city_id=1", "label": "https://latest.datasette.io/fixtures/facetable?_where=city_id=1"}]
authentication:permissions-plugins authentication permissions-plugins Checking permissions in plugins Datasette plugins can check if an actor has permission to perform an action using the datasette.permission_allowed(...) method. Datasette core performs a number of permission checks, documented below . Plugins can implement the permission_allowed(datasette, actor, action, resource) plugin hook to participate in decisions about whether an actor should be able to perform a specified action. ["Authentication and permissions"] []
authentication:authentication-actor-matches-allow authentication authentication-actor-matches-allow actor_matches_allow() Plugins that wish to implement this same "allow" block permissions scheme can take advantage of the datasette.utils.actor_matches_allow(actor, allow) function: from datasette.utils import actor_matches_allow actor_matches_allow({"id": "root"}, {"id": "*"}) # returns True The currently authenticated actor is made available to plugins as request.actor . ["Authentication and permissions"] []
authentication:permissionsdebugview authentication permissionsdebugview The permissions debug tool The debug tool at /-/permissions is only available to the authenticated root user (or any actor granted the permissions-debug action according to a plugin). It shows the thirty most recent permission checks that have been carried out by the Datasette instance. This is designed to help administrators and plugin authors understand exactly how permission checks are being carried out, in order to effectively configure Datasette's permission system. ["Authentication and permissions"] []
authentication:authentication-ds-actor authentication authentication-ds-actor The ds_actor cookie Datasette includes a default authentication plugin which looks for a signed ds_actor cookie containing a JSON actor dictionary. This is how the root actor mechanism works. Authentication plugins can set signed ds_actor cookies themselves like so: response = Response.redirect("/") response.set_cookie( "ds_actor", datasette.sign({"a": {"id": "cleopaws"}}, "actor"), ) Note that you need to pass "actor" as the namespace to .sign(value, namespace="default") . The shape of data encoded in the cookie is as follows: { "a": {... actor ...} } ["Authentication and permissions"] []
authentication:authentication-ds-actor-expiry authentication authentication-ds-actor-expiry Including an expiry time ds_actor cookies can optionally include a signed expiry timestamp, after which the cookies will no longer be valid. Authentication plugins may chose to use this mechanism to limit the lifetime of the cookie. For example, if a plugin implements single-sign-on against another source it may decide to set short-lived cookies so that if the user is removed from the SSO system their existing Datasette cookies will stop working shortly afterwards. To include an expiry, add a "e" key to the cookie value containing a base62-encoded integer representing the timestamp when the cookie should expire. For example, here's how to set a cookie that expires after 24 hours: import time from datasette.utils import baseconv expires_at = int(time.time()) + (24 * 60 * 60) response = Response.redirect("/") response.set_cookie( "ds_actor", datasette.sign( { "a": {"id": "cleopaws"}, "e": baseconv.base62.encode(expires_at), }, "actor", ), ) The resulting cookie will encode data that looks something like this: { "a": { "id": "cleopaws" }, "e": "1jjSji" } ["Authentication and permissions", "The ds_actor cookie"] []

binary_data:binary binary_data binary Binary data SQLite tables can contain binary data in BLOB columns. Datasette includes special handling for these binary values. The Datasette interface detects binary values and provides a link to download their content, for example on https://latest.datasette.io/fixtures/binary_data Binary data is represented in .json exports using Base64 encoding. https://latest.datasette.io/fixtures/binary_data.json?_shape=array [ { "rowid": 1, "data": { "$base64": true, "encoded": "FRwCx60F/g==" } }, { "rowid": 2, "data": { "$base64": true, "encoded": "FRwDx60F/g==" } }, { "rowid": 3, "data": null } ] [] [{"href": "https://latest.datasette.io/fixtures/binary_data", "label": "https://latest.datasette.io/fixtures/binary_data"}, {"href": "https://latest.datasette.io/fixtures/binary_data.json?_shape=array", "label": "https://latest.datasette.io/fixtures/binary_data.json?_shape=array"}]
binary_data:binary-linking binary_data binary-linking Linking to binary downloads The .blob output format is used to return binary data. It requires a _blob_column= query string argument specifying which BLOB column should be downloaded, for example: https://latest.datasette.io/fixtures/binary_data/1.blob?_blob_column=data This output format can also be used to return binary data from an arbitrary SQL query. Since such queries do not specify an exact row, an additional ?_blob_hash= parameter can be used to specify the SHA-256 hash of the value that is being linked to. Consider the query select data from binary_data - demonstrated here . That page links to the binary value downloads. Those links look like this: https://latest.datasette.io/fixtures.blob?sql=select+data+from+binary_data&_blob_column=data&_blob_hash=f3088978da8f9aea479ffc7f631370b968d2e855eeb172bea7f6c7a04262bb6d These .blob links are also returned in the .csv exports Datasette provides for binary tables and queries, since the CSV format does not have a mechanism for representing binary data.

changelog:id3 changelog id3 0.61 (2022-03-23) In preparation for Datasette 1.0, this release includes two potentially backwards-incompatible changes. Hashed URL mode has been moved to a separate plugin, and the way Datasette generates URLs to databases and tables with special characters in their name such as / and . has changed. Datasette also now requires Python 3.7 or higher. URLs within Datasette now use a different encoding scheme for tables or databases that include "special" characters outside of the range of a-zA-Z0-9_- . This scheme is explained here: Tilde encoding . ( #1657 ) Removed hashed URL mode from Datasette. The new datasette-hashed-urls plugin can be used to achieve the same result, see datasette-hashed-urls for details. ( #1661 ) Databases can now have a custom path within the Datasette instance that is independent of the database name, using the db.route property.

changelog:the-internal-database changelog the-internal-database 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.

changelog:named-in-memory-database-support changelog named-in-memory-database-support 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.

changelog:javascript-modules changelog javascript-modules 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.

changelog:id39 changelog id39 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 response. See datasette --get for an example.

changelog:id40 changelog id40 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 . ( #908 ) New logo for the documentation, and a new project tagline: "An open source multi-tool for exploring and publishing data". Whitespace in column values is now respected on display, using white-space: pre-wrap . ( #896 ) New await request.post_body() method for accessing the raw POST body, see Request object . ( #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.

changelog:authentication changelog authentication 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.

changelog:permissions changelog permissions 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 ) ["Changelog", "0.44 (2020-06-11)"] [{"href": "https://github.com/simonw/datasette/issues/788", "label": "#788"}]
changelog:writable-canned-queries changelog writable-canned-queries 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. ["Changelog", "0.44 (2020-06-11)"] [{"href": "https://latest.datasette.io/fixtures/neighborhood_search", "label": "https://latest.datasette.io/fixtures/neighborhood_search"}, {"href": "https://github.com/simonw/datasette/issues/800", "label": "#800"}]
changelog:flash-messages changelog flash-messages 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, 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 ["Changelog", "0.44 (2020-06-11)"] [{"href": "https://github.com/simonw/datasette/issues/790", "label": "#790"}, {"href": "https://latest.datasette.io/-/messages", "label": "https://latest.datasette.io/-/messages"}]
changelog:signed-values-and-secrets changelog signed-values-and-secrets 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. ["Changelog", "0.44 (2020-06-11)"] []
changelog:csrf-protection changelog csrf-protection 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() }}"> ["Changelog", "0.44 (2020-06-11)"] [{"href": "https://github.com/simonw/datasette/issues/798", "label": "#798"}]
