{"id": "authentication:authentication-permissions-allow", "page": "authentication", "ref": "authentication-permissions-allow", "title": "Defining permissions with \"allow\" blocks", "content": "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. \n                 The most basic form of allow block is this ( allow demo ,  deny demo ): \n                 {\n    \"allow\": {\n        \"id\": \"root\"\n    }\n} \n                 This will match any actors with an  \"id\"  property of  \"root\"  - for example, an actor that looks like this: \n                 {\n    \"id\": \"root\",\n    \"name\": \"Root User\"\n} \n                 An allow block can specify \"deny all\" using  false  ( demo ): \n                 {\n    \"allow\": false\n} \n                 An  \"allow\"  of  true  allows all access ( demo ): \n                 {\n    \"allow\": true\n} \n                 Allow keys can provide a list of values. These will match any actor that has any of those values ( allow demo ,  deny demo ): \n                 {\n    \"allow\": {\n        \"id\": [\"simon\", \"cleopaws\"]\n    }\n} \n                 This will match any actor with an  \"id\"  of either  \"simon\"  or  \"cleopaws\" . \n                 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: \n                 {\n    \"id\": \"simon\",\n    \"roles\": [\"staff\", \"developer\"]\n} \n                 This allow block will provide access to any actor that has  \"developer\"  as one of their roles ( allow demo ,  deny demo ): \n                 {\n    \"allow\": {\n        \"roles\": [\"developer\"]\n    }\n} \n                 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. \n                 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 ): \n                 {\n    \"allow\": {\n        \"id\": \"*\"\n    }\n} \n                 You can specify that only unauthenticated actors (from anynomous HTTP requests) should be allowed access using the special  \"unauthenticated\": true  key in an allow block ( allow demo ,  deny demo ): \n                 {\n    \"allow\": {\n        \"unauthenticated\": true\n    }\n} \n                 Allow keys act as an \"or\" mechanism. An actor will be able to execute the query if any of their JSON properties match any of the values in the corresponding lists in the  allow  block. The following block will allow users with either a  role  of  \"ops\"  OR users who have an  id  of  \"simon\"  or  \"cleopaws\" : \n                 {\n    \"allow\": {\n        \"id\": [\"simon\", \"cleopaws\"],\n        \"role\": \"ops\"\n    }\n} \n                 Demo for cleopaws ,  demo for ops role ,  demo for an actor matching neither rule .", "breadcrumbs": "[\"Authentication and permissions\", \"Permissions\"]", "references": "[{\"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\"}, {\"href\": \"https://latest.datasette.io/-/allow-debug?actor=null&allow=%7B%0D%0A++++%22unauthenticated%22%3A+true%0D%0A%7D\", \"label\": \"allow demo\"}, {\"href\": \"https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22hello%22%0D%0A%7D&allow=%7B%0D%0A++++%22unauthenticated%22%3A+true%0D%0A%7D\", \"label\": \"deny 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%2C%0D%0A++++%22role%22%3A+%22ops%22%0D%0A%7D\", \"label\": \"Demo for cleopaws\"}, {\"href\": \"https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22trevor%22%2C%0D%0A++++%22role%22%3A+%5B%0D%0A++++++++%22ops%22%2C%0D%0A++++++++%22staff%22%0D%0A++++%5D%0D%0A%7D&allow=%7B%0D%0A++++%22id%22%3A+%5B%0D%0A++++++++%22simon%22%2C%0D%0A++++++++%22cleopaws%22%0D%0A++++%5D%2C%0D%0A++++%22role%22%3A+%22ops%22%0D%0A%7D\", \"label\": \"demo for ops role\"}, {\"href\": \"https://latest.datasette.io/-/allow-debug?actor=%7B%0D%0A++++%22id%22%3A+%22percy%22%2C%0D%0A++++%22role%22%3A+%5B%0D%0A++++++++%22staff%22%0D%0A++++%5D%0D%0A%7D&allow=%7B%0D%0A++++%22id%22%3A+%5B%0D%0A++++++++%22simon%22%2C%0D%0A++++++++%22cleopaws%22%0D%0A++++%5D%2C%0D%0A++++%22role%22%3A+%22ops%22%0D%0A%7D\", \"label\": \"demo for an actor matching neither rule\"}]"}

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. \n             Datasette also now requires Python 3.7 or higher. \n             \n                 \n                     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 ) \n                 \n                 \n                     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.
