API rules

    API Rules are your collection access controls and data filters.

    Each collection has 5 rules, corresponding to the specific API action:

    • listRule
    • viewRule
    • createRule
    • updateRule
    • deleteRule

    Auth collections has an additional options.manageRule used to allow one user (it could be even from a different collection) to be able to fully manage the data of another user (eg. changing their email, password, etc.).

    Each rule could be set to:

    • "locked" - aka. null, which means that the action could be performed only by an authorized admin (this is the default)
    • Empty string - anyone will be able to perform the action (admins, authorized users and guests)
    • Non-empty string - only users (authorized or not) that satisfy the rule filter expression will be able to perform this action

    PocketBase API Rules act also as records filter!
    Or in other words, you could for example allow listing only the "active" records of your collection, by using a simple filter expression such as: status = "active" (where "status" is a field defined in your Collection).

    Because of the above, the API will return 200 empty items response in case a request doesn't satisfy a listRule, 400 for unsatisfied createRule and 404 for unsatisfied viewRule, updateRule and deleteRule.
    All rules will return 403 in case they were "locked" (aka. admin only) and the request client is not an admin.

    The API Rules are ignored when the action is performed by an authorized admin (admins can access everything)!

    Filters syntax

    You could find information about the supported fields in your collection API rules tab:

    There is autocomplete to help you guide you while typing the rule filter expression, but in general, you have access to 3 groups of fields:

    • Your Collection schema fields
      This also include all nested relations fields too, eg. someRelField.status != "pending"
    • @request.*
      Used to access the current request data, such as query parameters, body/form data, authorized user state, etc.
      • @request.method - the HTTP request method (eg. @request.method = "GET")
      • @request.headers.* - the request headers as string values (eg. @request.headers.x_token = "test")
        Note: All header keys are normalized to lowercase and "-" is replaced with "_" (for example "X-Token" is "x_token").
      • @request.query.* - the request query parameters as string values (eg. @request.query.page = "1")
      • @request.data.* - the submitted body parameters (eg. @request.data.title != "")
      • @request.auth.* - the current authenticated model (eg. @request.auth.id != '')
    • @collection.*
      This filter could be used to target other collections that are not directly related to the current one (aka. there is no relation field pointing to it) but both shares a common field value, like for example a category id:
      @collection.news.categoryId ?= categoryId && @collection.news.author ?= @request.auth.id

    The syntax basically follows the format OPERAND OPERATOR OPERAND, where:

    • OPERAND - could be any of the above field literal, string (single or double quoted), number, null, true, false
    • OPERATOR - is one of:
      • = Equal
      • != NOT equal
      • > Greater than
      • >= Greater than or equal
      • < Less than
      • <= Less than or equal
      • ~ Like/Contains (if not specified auto wraps the right string OPERAND in a "%" for wildcard match)
      • !~ NOT Like/Contains (if not specified auto wraps the right string OPERAND in a "%" for wildcard match)
      • ?= Any/At least one of Equal
      • ?!= Any/At least one of NOT equal
      • ?> Any/At least one of Greater than
      • ?>= Any/At least one of Greater than or equal
      • ?< Any/At least one of Less than
      • ?<= Any/At least one of Less than or equal
      • ?~ Any/At least one of Like/Contains (if not specified auto wraps the right string OPERAND in a "%" for wildcard match)
      • ?!~ Any/At least one of NOT Like/Contains (if not specified auto wraps the right string OPERAND in a "%" for wildcard match)

    To group and combine several expressions you could use parenthesis (...), && (AND) and || (OR) tokens.

    Special identifiers and modifiers

    @ macros

    The following datetime macros are available and can be used as part of the filter expression:

    // all macros are UTC based @now - the current datetime as string @second - @now second number (0-59) @minute - @now minute number (0-59) @hour - @now hour number (0-23) @weekday - @now weekday number (0-6) @day - @now day number @month - @now month number @year - @now year number @todayStart - beginning of the current day as datetime string @todayEnd - end of the current day as datetime string @monthStart - beginning of the current month as datetime string @monthEnd - end of the current month as datetime string @yearStart - beginning of the current year as datetime string @yearEnd - end of the current year as datetime string

    For example:

    @request.data.publicDate >= @now
    :isset modifier

    The :isset field modifier is available only for the @request.* fields and can be used to check whether the client submitted a specific data with the request. Here is for example a rule that disallows changing a "role" field:

    @request.data.role:isset = false
    :length modifier

    The :length field modifier could be used to check the number of items in an array field (multiple file, select, relation).
    Could be used with both the collection schema fields and the @request.data.* fields. For example:

    // check example submitted data: {"someSelectField": ["val1", "val2"]} @request.data.someSelectField:length > 1 // check existing record field length someRelationField:length = 2
    :each modifier

    The :each field modifier works only with multiple select fields. It could be used to apply a condition on each select item. For example:

    // check if all submitted select options contain the "create" text @request.data.someSelectField:each ~ "create" // check if all existing someSelectField has "pb_" prefix someSelectField:each ~ 'pb_%'

    Examples

    • Allow only registered users:
      @request.auth.id != ""
    • Allow only registered users and return records that are either "active" or "pending":
      @request.auth.id != "" && (status = "active" || status = "pending")
    • Allow only registered users who are listed in an allowed_users multi-relation field value:
      @request.auth.id != "" && allowed_users.id ?= @request.auth.id
    • Allow access by anyone and return only the records where the title field value starts with "Lorem" (eg. "Lorem ipsum"):
      title ~ "Lorem%"
