Warning: This release fixes a reflected cross-site scripting security hole with the ?_trace=1 feature. You should upgrade to this version, or to Datasette 0.56.1, as soon as possible. (#1360)

In addition to the security fix, this release includes ?_col= and ?_nocol= options for controlling which columns are displayed for a table, ?_facet_size= for increasing the number of facet results returned, re-display of your SQL query should an error occur and numerous bug fixes.

New features

  • If an error occurs while executing a user-provided SQL query, that query is now re-displayed in an editable form along with the error message. (#619)
  • New ?_col= and ?_nocol= parameters to show and hide columns in a table, plus an interface for hiding and showing columns in the column cog menu. (#615)
  • A new ?_facet_size= parameter for customizing the number of facet results returned on a table or view page. (#1332)
  • ?_facet_size=max sets that to the maximum, which defaults to 1,000 and is controlled by the the max_returned_rows setting. If facet results are truncated the ... at the bottom of the facet list now links to this parameter. (#1337)
  • ?_nofacet=1 option to disable all facet calculations on a page, used as a performance optimization for CSV exports and ?_shape=array/object. (#1349, #263)
  • ?_nocount=1 option to disable full query result counts. (#1353)
  • ?_trace=1 debugging option is now controlled by the new trace_debug setting, which is turned off by default. (#1359)

Bug fixes and other improvements

  • Custom pages now work correctly when combined with the base_url setting. (#1238)
  • Fixed intermittent error displaying the index page when the user did not have permission to access one of the tables. Thanks, Guy Freeman. (#1305)
  • Columns with the name "Link" are no longer incorrectly displayed in bold. (#1308)
  • Fixed error caused by tables with a single quote in their names. (#1257)
  • Updated dependencies: pytest-asyncio, Black, jinja2, aiofiles, click, and itsdangerous.
  • The official Datasette Docker image now supports apt-get install. (#1320)
  • The Heroku runtime used by datasette publish heroku is now python-3.8.10.

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.

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.

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.

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.

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)

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)

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 underlying queries exceeded a time limit. (#1088)
  • Fixed a bug where the table action menu could appear partially obscured by the edge of the page. (#1084)

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.

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)

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.

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).

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)

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)

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. (#1053)

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)

Warning: 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. (#456)
  • The Datasette package published to PyPI now includes sdist as well as bdist_wheel.
  • Better titles for canned query pages. (#887)
  • Now only loads Python files from a directory passed using the --plugins-dir option - thanks, Amjith Ramanujam. (#890)
  • New documentation section on Publishing to Vercel.

Magic parameters for canned queries, a log out feature, improved plugin documentation and four new plugin hooks.

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)
  (:_actor_id, :_now_datetime_utc)

This inserts the currently authenticated actor ID and the current datetime. (#842)

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)

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 simple one-off 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.

New plugin hooks

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)

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)

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.

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.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 Install using pipx. (#756)
  • Improved the documentation for Full-text search.

  • 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)

The big new feature in this release is facets. Datasette can now apply faceted browse to any column in any table. It will also suggest possible facets. See the Datasette Facets announcement post for more details.

In addition to the work on facets:

Removed the --page_size= argument to datasette serve in favour of:

  datasette serve --config default_page_size:50 mydb.db

Added new help section:

  $ datasette --help-config
  Config options:
    default_page_size            Default page size for the table view
    max_returned_rows            Maximum rows that can be returned from a table
                                 or custom query (default=1000)
    sql_time_limit_ms            Time limit for a SQL query in milliseconds
    default_facet_size           Number of values to return for requested facets
    facet_time_limit_ms          Time limit for calculating a requested facet
    facet_suggest_time_limit_ms  Time limit for calculating a suggested facet
  • Only apply responsive table styles to .rows-and-column

New JSON _shape= options, the ability to set table _size= and a mechanism for searching within specific columns.

  • Default tests to using a longer timelimit

    Every now and then a test will fail in Travis CI on Python 3.5 because it hit the default 20ms SQL time limit.

    Test fixtures now default to a 200ms time limit, and we only use the 20ms time limit for the specific test that tests query interruption.

    This should make our tests on Python 3.5 in Travis much more stable.

  • Support _search_COLUMN=text searches, closes #237

  • Show version on /-/plugins page, closes #248

  • ?_size=max option, closes #249

  • Added /-/versions and /-/versions.json, closes #244

  • New hidden: True option for table metadata, closes #239

  • Hide idx_* tables if spatialite detected, closes #228

Mostly new work on the Plugins mechanism: plugins can now bundle static assets and custom templates, and datasette publish has a new --install=name-of-plugin option.

  • Add col-X classes to HTML table on custom query page
  • Fixed out-dated template in documentation
  • Plugins can now bundle custom templates, #224
  • Added /-/metadata /-/plugins /-/inspect, #225
  • Documentation for --install option, refs #223
  • Datasette publish/package --install option, #223
  • Fix for plugins in Python 3.5, #222
  • New plugin hooks: extra_css_urls() and extra_js_urls(), #214
  • /-/static-plugins/PLUGIN_NAME/ now serves static/ from plugins
  • <th> now gets class="col-X" - plus added col-X documentation
  • Use to_css_class for table cell column classes

This ensures that columns with spaces in the name will still
generate usable CSS class names. Refs #209
- Add column name classes to <td>s, make PK bold [Russ Garrett]
- Don't duplicate simple primary keys in the link column [Russ Garrett]

When there's a simple (single-column) primary key, it looks weird to
duplicate it in the link column.

This change removes the second PK column and treats the link column as
if it were the PK column from a header/sorting perspective.
- Correct escaping for HTML display of row links [Russ Garrett]
- Longer time limit for test_paginate_compound_keys

It was failing intermittently in Travis - see #209
- Use application/octet-stream for downloadable databses
- Updated PyPI classifiers
- Updated PyPI link to pypi.org

This is the first preview of the new Datasette plugins mechanism. Only two plugin hooks are available so far - for custom SQL functions and custom template filters. There's plenty more to come - read the documentation and get involved in the tracking ticket if you have feedback on the direction so far.

  • Fix for _sort_desc=sortable_with_nulls test, refs #216

  • Fixed #216 - paginate correctly when sorting by nullable column

  • Initial documentation for plugins, closes #213


  • New --plugins-dir=plugins/ option (#212)

New option causing Datasette to load and evaluate all of the Python files in the specified directory and register any plugins that are defined in those files.

This new option is available for the following commands:

  datasette serve mydb.db --plugins-dir=plugins/
  datasette publish now/heroku mydb.db --plugins-dir=plugins/
  datasette package mydb.db --plugins-dir=plugins/
  • Start of the plugin system, based on pluggy (#210)

Uses https://pluggy.readthedocs.io/ originally created for the py.test project

We're starting with two plugin hooks:


This is called when a new SQLite connection is created. It can be used to register custom SQL functions.


This is called with the Jinja2 environment. It can be used to register custom template tags and filters.

An example plugin which uses these two hooks can be found at https://github.com/simonw/datasette-plugin-demos or installed using pip install datasette-plugin-demos

Refs #14

  • Return HTTP 405 on InvalidUsage rather than 500. [Russ Garrett]

This also stops it filling up the logs. This happens for HEAD requests at the moment - which perhaps should be handled better, but that's a different issue.

This release introduces support for units, contributed by Russ Garrett (#203). You can now optionally specify the units for specific columns using metadata.json. 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.

  • Link foreign keys which don't have labels. [Russ Garrett]

    This renders unlabeled FKs as simple links.

    Also includes bonus fixes for two minor issues:

    • In foreign key link hrefs the primary key was escaped using HTML escaping rather than URL escaping. This broke some non-integer PKs.
    • Print tracebacks to console when handling 500 errors.
  • Fix SQLite error when loading rows with no incoming FKs. [Russ Garrett]

    This fixes ERROR: conn=<sqlite3.Connection object at 0x10bbb9f10>, sql = 'select ', params = {'id': '1'} caused by an invalid query when loading incoming FKs.

    The error was ignored due to async but it still got printed to the console.

  • Allow custom units to be registered with Pint. [Russ Garrett]

  • Support units in filters. [Russ Garrett]

  • Tidy up units support. [Russ Garrett]

    • Add units to exported JSON
    • Units key in metadata skeleton
    • Docs
  • Initial units support. [Russ Garrett]

  • Allow explain select / explain query plan select #201

  • Datasette inspect now finds primary_keys #195

  • Ability to sort using form fields (for mobile portrait mode) #199

    We now display sort options as a select box plus a descending checkbox, which means you can apply sort orders even in portrait mode on a mobile phone where the column headers are hidden.

The biggest new feature in this release is the ability to sort by column. On the table page the column headers can now be clicked to apply sort (or descending sort), or you can specify ?_sort=column or ?_sort_desc=column directly in the URL.

You can try this feature out on this fivethirtyeight data about the ages of different US politicians.

  • table_rows => table_rows_count, filtered_table_rows => filtered_table_rows_count

    Renamed properties. Closes #194

  • New sortable_columns option in metadata.json to control sort options.

    You can now explicitly set which columns in a table can be used for sorting using the _sort and _sort_desc arguments using metadata.json:

        "databases": {
            "database1": {
                "tables": {
                    "example_table": {

  • Database/Table views inherit source/license/source_url/license_url metadata

    If you set the source_url/license_url/source/license fields in your root metadata those values will now be inherited all the way down to the database and table templates.

    The title/description are NOT inherited.

    Also added unit tests for the HTML generated by the metadata.

8841695 https://github.com/simonw/datasette/releases/tag/0.14 MDc6UmVsZWFzZTg4NDE2OTU= 0.14 main Datasette 0.14: customization edition 0 simonw 9599 0 2017-12-10T01:33:24Z 2017-12-10T01:41:14Z

The theme of this release is customization: Datasette now allows every aspect 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": [

    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": [
                "url": "https://simonwillison.net/static/css/all.bf8cd891642c.css",
                "sri": "sha384-9qIZekWUyjCyDIf2YK1FRoKiPJq4PHt6tp/ulnuuyRBvazd0hG7pWbE99zvwSznI"
        "extra_js_urls": [
                "url": "https://code.jquery.com/jquery-3.2.1.slim.min.js",
                "sri": "sha256-k2WSCIexGzOj3Euiig+TlR8gA0EmPjuc79OEeY5L45g="

    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/

  • Auto-link column values that look like URLs (#153)

  • CSS styling hooks as classes on the body (#153)

    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"
    "_no-leading-underscores" => "no-leading-underscores-b921bc"
    "no spaces" => "no-spaces-7088d7"
    "-" => "336d5e"
    "no $ characters" => "no--characters-59e024"
  • datasette --template-dir=mytemplates/ argument

    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.

  • Ability to over-ride templates for individual tables/databases.

    It is now possible to over-ride templates on a per-database / per-row or per-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 (/):
    Database page (/mydatabase):
    Table page (/mydatabase/mytable):
    Row page (/mydatabase/mytable/id):

    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:


    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 %}
    <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:


    The following file will be served:

  • 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)

  • metadata.json support for per-table/per-database metadata (#165)

    Also added support for descriptions and HTML descriptions.

    Here's an example metadata.json file illustrating custom per-database and per-table metadata:

        "title": "Overall datasette title",
        "description_html": "This is a <em>description with HTML</em>.",
        "databases": {
            "db1": {
                "title": "First database",
                "description": "This is a string description & has no HTML",
                "license_url": "http://example.com/",
            "license": "The example license",
                "queries": {
                  "canned_query": "select * from table1 limit 3;"
                "tables": {
                    "table1": {
                        "title": "Custom title for table1",
                        "description": "Tables can have descriptions too",
                        "source": "This has a custom source",
                        "source_url": "http://example.com/"
  • Renamed datasette build command to datasette inspect (#130)

  • Upgrade to Sanic 0.7.0 (#168)


  • Package and publish commands now accept --static and --template-dir

    Example usage:

    datasette package --static css:extra-css/ --static js:extra-js/ \
      sf-trees.db --template-dir templates/ --tag sf-trees --branch master

    This creates a local Docker image that includes copies of the templates/, extra-css/ and extra-js/ directories. You can then run it like this:

    docker run -p 8001:8001 sf-trees

    For publishing to Zeit now:

    datasette publish now --static css:extra-css/ --static js:extra-js/ \
      sf-trees.db --template-dir templates/ --name sf-trees --branch master

  • Search now applies to current filters.

    Combined search into the same form as filters.

    Closes #133

  • Much tidier design for table view header.

    Closes #147

  • Added ?column__not=blah filter.

    Closes #148

  • Row page now resolves foreign keys.

    Closes #132

  • Further tweaks to select/input filter styling.

    Refs #86 - thanks for the help, @natbat!

  • Show linked foreign key in table cells.

  • Added UI for editing table filters.

  • Add publish to heroku support [Jacob Kaplan-Moss]

    datasette publish heroku mydb.db

    Pull request #104

  • Initial implementation of ?_group_count=column.

    URL shortcut for counting rows grouped by one or more columns.

    ?_group_count=column1&_group_count=column2 works as well.

    SQL generated looks like this:

    select "qSpecies", count(*) as "count"
    from Street_Tree_List
    group by "qSpecies"
    order by "count" desc limit 100

    Or for two columns like this:

    select "qSpecies", "qSiteInfo", count(*) as "count"
    from Street_Tree_List
    group by "qSpecies", "qSiteInfo"
    order by "count" desc limit 100

    Refs #44

  • Added --build=master option to datasette publish and package.

    The datasette publish and datasette package commands both now
    accept an optional --build argument. If provided, this can be used
    to specify a branch published to GitHub that should be built into
    the container.

    This makes it easier to test code that has not yet been officially
    released to PyPI, e.g.:

    datasette publish now mydb.db --branch=master
  • 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

  • Added __version__, now displayed as tooltip in page footer
  • Added initial docs, including a changelog (#99).
  • Turned on auto-escaping in Jinja.
  • Added a UI for editing named parameters (#96).

    You can now construct a custom SQL statement using SQLite named parameters (e.g. :name) and datasette will display form fields for editing those parameters. Here's an example which lets you see the most popular names for dogs of different species registered through various dog registration schemes in Australia.
    - Pin to specific Jinja version. (#100).
    - Default to not (#98).
    - Added extra metadata options to publish and package commands.

    You can now run these commands like so:

    datasette now publish mydb.db \
        --title="My Title" \
        --source="Source" \
        --source_url="http://www.example.com/" \
        --license="CC0" \

    This will write those values into the metadata.json that is packaged
    with the app. If you also pass --metadata=metadata.json that file
    will be updated with the extra values before being written into the
    Docker image.

  • Added simple production-ready Dockerfile (#94) [Andrew Cutler]

  • New ?_sql_time_limit_ms=10 argument to database and table page
