google.cloud.bigquery.dataset.AccessEntry

class google.cloud.bigquery.dataset.AccessEntry(role, entity_type, entity_id)

Represents grant of an access role to an entity.

An entry must have exactly one of the allowed ENTITY_TYPES. If anything but view or routine are set, a role is also required. role is omitted for view and routine, because they are always read-only.

See https://cloud.google.com/bigquery/docs/reference/rest/v2/datasets.

Parameters

• role (str) – Role granted to the entity. The following string values are supported: ‘READER’, ‘WRITER’, ‘OWNER’. It may also be None if the entity_type is view or routine.

• entity_type (str) – Type of entity being granted the role. One of ENTITY_TYPES.

• entity_id (Union[str, Dict[str, str]]) –

  If the entity_type is not ‘view’ or ‘routine’, the entity_id is the str ID of the entity being granted the role. If the entity_type is ‘view’ or ‘routine’, the entity_id is a dict representing the view or routine from a different dataset to grant access to in the following format for views:

  {
      'projectId': string,
      'datasetId': string,
      'tableId': string
  }
  

  For routines:

  {
      'projectId': string,
      'datasetId': string,
      'routineId': string
  }
  

Raises

ValueError – If the entity_type is not among ENTITY_TYPES, or if a view or a routine has role set, or a non view and non routine does not have a role set.

Examples

>>> entry = AccessEntry('OWNER', 'userByEmail', 'user@example.com')

>>> view = {
...     'projectId': 'my-project',
...     'datasetId': 'my_dataset',
...     'tableId': 'my_table'
... }
>>> entry = AccessEntry(None, 'view', view)
