authentication:allowdebugview authentication allowdebugview The /-/allow-debug tool The /-/allow-debug tool lets you try out different "action" blocks against different "actor" JSON objects. You can try that out here: https://latest.datasette.io/-/allow-debug ["Authentication and permissions", "Permissions"] [{"href": "https://latest.datasette.io/-/allow-debug", "label": "https://latest.datasette.io/-/allow-debug"}]
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-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: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"] []
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-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-execute-sql authentication authentication-permissions-execute-sql Controlling the ability to execute arbitrary SQL Datasette defaults to allowing any site visitor to execute their own custom SQL queries, for example using the form on the database page or by appending a ?_where= parameter to the table page like this . Access to this ability is controlled by the execute-sql permission. The easiest way to disable arbitrary SQL queries is using the default_allow_sql setting when you first start Datasette running. You can alternatively use an "allow_sql" block to control who is allowed to execute arbitrary SQL queries. To prevent any user from executing arbitrary SQL queries, use this: { "allow_sql": false } 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": "the database page"}, {"href": "https://latest.datasette.io/fixtures/facetable?_where=_city_id=1", "label": "like this"}]
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-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-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-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: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.

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.

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 .

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.

changelog:control-http-caching-with-ttl changelog control-http-caching-with-ttl Control HTTP caching with ?_ttl= You can now customize the HTTP max-age header that is sent on a per-URL basis, using the new ?_ttl= query string parameter. You can set this to any value in seconds, or you can set it to 0 to disable HTTP caching entirely. Consider for example this query which returns a randomly selected member of the Avengers: select * from [avengers/avengers] order by random() limit 1 If you hit the following page repeatedly you will get the same result, due to HTTP caching: /fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1 By adding ?_ttl=0 to the zero you can ensure the page will not be cached and get back a different super hero every time: /fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1&_ttl=0 ["Changelog", "0.23 (2018-06-18)"] [{"href": "https://fivethirtyeight.datasettes.com/fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1", "label": "/fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1"}, {"href": "https://fivethirtyeight.datasettes.com/fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1&_ttl=0", "label": "/fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1&_ttl=0"}]

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 an error caused by an invalid query when loading incoming FKs.

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.

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.

( #69 ) If someone executes 'select * from table' against a table with a million rows in it, we could run into problems: just serializing that much data as JSON is likely to lock up the server. Solution: we now have a hard limit on the maximum number of rows that can be returned by a query. If that limit is exceeded, the server will return a "truncated": true field in the JSON. This limit can be optionally controlled by the new --max_returned_rows option. Setting that option to 0 disables the limit entirely.
