    • Get the explicit permission level that a User has over this Document, a value in CONST.DOCUMENT_OWNERSHIP_LEVELS. Compendium content ignores the ownership field in favor of User role-based ownership. Otherwise, Documents use granular per-User ownership definitions and Embedded Documents defer to their parent ownership.

      This method returns the value recorded in Document ownership, regardless of the User's role, for example a GAMEMASTER user might still return a result of NONE if they are not explicitly denoted as having a level.

      To test whether a user has a certain capability over the document, testUserPermission should be used.

      Parameters

      • Optionaluser: BaseUser

        The User being tested

      Returns DocumentOwnershipNumber

      A numeric permission level from CONST.DOCUMENT_OWNERSHIP_LEVELS

      • Optionalcontext: object

        Contextual information for use in the determination

      Returns boolean

    • Returns void

    • Returns void

    • Reset the state of this data instance back to mirror the contained source data, erasing any changes.

      Returns void

    • Assign a "flag" to this document. Flags represent key-value type data which can be used to store flexible or arbitrary data required by either the core software, game systems, or user-created modules.

      Each flag should be set using a scope which provides a namespace for the flag to help prevent collisions.

      Flags set by the core software use the "core" scope. Flags set by game systems or modules should use the canonical name attribute for the module Flags set by an individual world should "world" as the scope.

      Flag values can assume almost any data type. Setting a flag value to null will delete that flag.

      Parameters

      • scope: string

        The flag scope which namespaces the key

      • key: string

        The flag key

      • value: any

    • Update the DataModel locally by applying an object of changes to its source data. The provided changes are expanded, cleaned, validated, and stored to the source data object for this model.

The method returns an object of differential changes which modified the original data.

      Parameters

      • changes: object = {}

        New values which should be applied to the data model

      Returns object

      An object containing differential keys and values that were changed

      An error if the requested data model changes were invalid

    • Validate the data contained in the document to check for type and content. This method is intended to validate complete model records, verifying both individual field validation as well as joint model validity.

      For validating sets of partial model changes, it is preferred to call DataModel#updateSource as a dryRun. This method provides a convenience alias for such a workflow if changes are provided.

      Warning: if fallback handling is allowed, this process will mutate provided changes or model source data.

      Parameters

      Returns boolean

      Whether the data source or proposed change is reported as valid. A boolean is always returned if validation is non-strict.

      An error thrown if validation is strict and a failure occurs.

    • Evaluate joint validation rules which apply validation conditions across multiple fields of the model. Field-specific validation rules should be defined as part of the DataSchema for the model. This method allows for testing aggregate rules which impose requirements on the overall model.

      Parameters

      • data: object

        Candidate data for the model

      Returns void

      An error if a validation failure is detected

      Apply an ActiveEffect that uses an "add" change type. The way that effects are added depends on the data type of the current value.

      If the current value is null, the change value is assigned directly. If the current type is a string, the change value is concatenated. If the current type is a number, the change value is cast to numeric and added. If the current type is an array, the change value is appended to the existing array if it matches in type.

      Apply an ActiveEffect that uses a "subtract" change type. The way that effects are added depends on the data type of the current value.

      If the current value is null, the change value is assigned directly. If the current type is a string, the change value is replaced in the current value with the empty string. If the current type is a number, the change value is cast to numeric and subtracted. If the current type is an array, the change value is spliced out of the array if present.

      Apply final custom model-specific cleaning rules after data schema fields are cleaned. Subclass models can implement this function as an ideal place to apply custom imputation or cleaning. Cleaning must be done in-place rather than returning a different object.

      Modifications to pending documents must mutate the documents array or alter individual document instances using updateSource.

      Parameters

      Returns Promise<boolean | void>

      Return false to cancel the creation operation entirely

      Pre-process a deletion operation, potentially altering its instructions or input data. Pre-operation events only occur for the client which requested the operation.

      This batch-wise workflow occurs after individual _preDelete workflows and provides a final pre-flight check before a database operation occurs.

      Modifications to the requested deletions are performed by mutating the operation object. updateSource.

      Parameters

      Returns Promise<boolean | void>

      Return false to cancel the deletion operation entirely
