changelog:configuration,changelog,configuration,Configuration,"Plugin configuration now lives in the  datasette.yaml configuration file , passed to Datasette using the  -c/--config  option. Thanks, Alex Garcia. ( #2093 ) 
                         datasette -c datasette.yaml 
                         Where  datasette.yaml  contains configuration that looks like this: 
                         plugins:
  datasette-cluster-map:
    latitude_column: xlat
    longitude_column: xlon 
                         Previously plugins were configured in  metadata.yaml , which was confusing as plugin settings were unrelated to database and table metadata. 
                     
                     
                         The  -s/--setting  option can now be used to set plugin configuration as well. See  Configuration via the command-line  for details. ( #2252 ) 
                         The above YAML configuration example using  -s/--setting  looks like this: 
                         datasette mydatabase.db \
  -s plugins.datasette-cluster-map.latitude_column xlat \
  -s plugins.datasette-cluster-map.longitude_column xlon 
                     
                     
                         The new  /-/config  page shows the current instance configuration, after redacting keys that could contain sensitive data such as API keys or passwords. ( #2254 ) 
                     
                     
                         Existing Datasette installations may already have configuration set in  metadata.yaml  that should be migrated to  datasette.yaml . To avoid breaking these installations, Datasette will silently treat table configuration, plugin configuration and allow blocks in metadata as if they had been specified in configuration instead. ( #2247 ) ( #2248 ) ( #2249 ) 
                     
                 
                 Note that the  datasette publish  command has not yet been updated to accept a  datasette.yaml  configuration file. This will be addressed in  #2195  but for the moment you can include those settings in  metadata.yaml  instead.","[""Changelog"", ""1.0a8 (2024-02-07)""]","[{""href"": ""https://github.com/simonw/datasette/issues/2093"", ""label"": ""#2093""}, {""href"": ""https://github.com/simonw/datasette/issues/2252"", ""label"": ""#2252""}, {""href"": ""https://github.com/simonw/datasette/issues/2254"", ""label"": ""#2254""}, {""href"": ""https://github.com/simonw/datasette/issues/2247"", ""label"": ""#2247""}, {""href"": ""https://github.com/simonw/datasette/issues/2248"", ""label"": ""#2248""}, {""href"": ""https://github.com/simonw/datasette/issues/2249"", ""label"": ""#2249""}, {""href"": ""https://github.com/simonw/datasette/issues/2195"", ""label"": ""#2195""}]"

changelog:id18,changelog,id18,0.61 (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 )

                     Databases can now have a custom path within the Datasette instance that is independent of the database name, using the  db.route  property. ( #1668 )

                     Implemented  ?_search=XXX  + UI if a FTS table is detected. 
                     Closes  #131 
                 
                 
                     Added  datasette --version  support. 
                 
                 
                     Table views now show expanded foreign key references, if possible. 
                     If a table has foreign key columns, and those foreign key tables have
                         label_columns , the TableView will now query those other tables for the
                        corresponding values and display those values as links in the corresponding
                        table cells. 
                     label_columns are currently detected by the  inspect()  function, which looks
                        for any table that has just two columns - an ID column and one other - and
                        sets the  label_column  to be that second non-ID column.

                Once specified, units will be displayed in the HTML view of your table. They also become
                available for use in filters - if a column is configured with a unit of distance, you can
                request all rows where that column is less than 50 meters or more than 20 feet for example.

                of its presentation  to be customized 
                either using additional CSS or by providing entirely new templates. 
             Datasette's  metadata.json format 
                has also been expanded, to allow per-database and per-table metadata. A new
                 datasette skeleton  command can be used to generate a skeleton JSON file
                ready to be filled in with per-database and per-table details. 
             The  metadata.json  file can also be used to define
                 canned queries ,
                as a more powerful alternative to SQL views. 
             
                 
                     extra_css_urls / extra_js_urls  in metadata 
                     A mechanism in the  metadata.json  format for adding custom CSS and JS urls. 
                     Create a  metadata.json  file that looks like this:

    ""extra_css_urls"": [

    ""extra_js_urls"": [
        ""https://code.jquery.com/jquery-3.2.1.slim.min.js""

                     Then start datasette like this: 
                     datasette mydb.db --metadata=metadata.json 
                     The CSS and JavaScript files will be linked in the  <head>  of every page. 
                     You can also specify a SRI (subresource integrity hash) for these assets: 
                     {
    ""extra_css_urls"": [
        {

        }

} 
                     Modern browsers will only execute the stylesheet or JavaScript if the SRI hash
                        matches the content served. You can generate hashes using  https://www.srihash.org/

                     Every template now gets CSS classes in the body designed to support custom
                        styling. 
                     The index template (the top level page at  / ) gets this: 
                     <body class=""index""> 
                     The database template ( /dbname/ ) gets this: 
                     <body class=""db db-dbname""> 
                     The table template ( /dbname/tablename ) gets: 
                     <body class=""table db-dbname table-tablename""> 
                     The row template ( /dbname/tablename/rowid ) gets: 
                     <body class=""row db-dbname table-tablename""> 
                     The  db-x  and  table-x  classes use the database or table names themselves IF
                        they are valid CSS identifiers. If they aren't, we strip any invalid
                        characters out and append a 6 character md5 digest of the original name, in
                        order to ensure that multiple tables which resolve to the same stripped
                        character version still have different CSS classes. 
                     Some examples (extracted from the unit tests): 
                     ""simple"" => ""simple""
""MixedCase"" => ""MixedCase""
""-no-leading-hyphens"" => ""no-leading-hyphens-65bea6""

                     You can now pass an additional argument specifying a directory to look for
                        custom templates in. 
                     Datasette will fall back on the default templates if a template is not
                        found in that directory.

                        table basis. 
                     When you access e.g.  /mydatabase/mytable  Datasette will look for the following: 
                     - table-mydatabase-mytable.html
- table.html 
                     If you provided a  --template-dir  argument to datasette serve it will look in
                        that directory first. 
                     The lookup rules are as follows: 
                     Index page (/):
    index.html

Database page (/mydatabase):
    database-mydatabase.html
    database.html

Table page (/mydatabase/mytable):
    table-mydatabase-mytable.html
    table.html

Row page (/mydatabase/mytable/id):
    row-mydatabase-mytable.html
    row.html 
                     If a table name has spaces or other unexpected characters in it, the template
                        filename will follow the same rules as our custom  <body>  CSS classes
                        - for example, a table called ""Food Trucks""
                        will attempt to load the following templates: 
                     table-mydatabase-Food-Trucks-399138.html
table.html 
                     It is possible to extend the default templates using Jinja template
                        inheritance. If you want to customize EVERY row template with some additional
                        content you can do so by creating a row.html template like this: 
                     {% extends ""default:row.html"" %}

{% block content %}
<h1>EXTRA HTML AT THE TOP OF THE CONTENT BLOCK</h1>
<p>This line renders the original block:</p>
{{ super() }}
{% endblock %} 
                 
                 
                     --static  option for datasette serve ( #160 ) 
                     You can now tell Datasette to serve static files from a specific location at a
                        specific mountpoint. 
                     For example: 
                     datasette serve mydb.db --static extra-css:/tmp/static/css 
                     Now if you visit this URL: 
                     http://localhost:8001/extra-css/blah.css 
                     The following file will be served: 
                     /tmp/static/css/blah.css 
                 
                 
                     Canned query support. 
                     Named canned queries can now be defined in  metadata.json  like this: 
                     {
    ""databases"": {
        ""timezones"": {
            ""queries"": {
                ""timezone_for_point"": ""select tzid from timezones ...""
            }
        }
    }
} 
                     These will be shown in a new ""Queries"" section beneath ""Views"" on the database page. 
                 
                 
                     New  datasette skeleton  command for generating  metadata.json  ( #164 )

                     Also added support for descriptions and HTML descriptions. 
                     Here's an example metadata.json file illustrating custom per-database and per-

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 .
