Loading Statements from External Source

If you don't want your policy statements hardcoded into the classes, you can load them from an external data source: a great step because you can change access rules without redeploying code.

Just define a method on your policy class called get_policy_statements, which has the following signature: get_policy_statements(self, request, view) -> List[dict]


class UserAccessPolicy(AccessPolicy):
    id = 'user-policy'

    def get_policy_statements(self, request, view) -> List[dict]:
        statements = data_api.load_json(
        return json.loads(statements)

You probably want to only define this method once on your own custom subclass of AccessPolicy, from which all your other access policies inherit.
