Records permission policies.

Default policies for records:

.. code-block:: python

    # Read access given to everyone.
    can_search = [AnyUser()]
    # Create action given to no one (Not even superusers) bc Deposits should
    # be used.
    can_create = [Disable()]
    # Read access given to everyone if public record/files and owners always.
    can_read = [AnyUserIfPublic(), RecordOwners()]
    # Update access given to record owners.
    can_update = [RecordOwners()]
    # Delete access given to admins only.
    can_delete = [Admin()]
    # Associated files permissions (which are really bucket permissions)
    can_read_files = [AnyUserIfPublic(), RecordOwners()]
    can_update_files = [RecordOwners()]

How to override default policies for records.

Using Custom Generator for a policy:

.. code-block:: python

    from invenio_rdm_records.permissions import RDMRecordPermissionPolicy
    from invenio_config_tugraz.generators import RecordIp

    class TUGRAZPermissionPolicy(RDMRecordPermissionPolicy):

    # Delete access given to RecordIp only.

    can_delete = [RecordIp()]

    RECORDS_PERMISSIONS_RECORD_POLICY = TUGRAZPermissionPolicy
