Description

When using:

$ docker exec  galaxy_ng_api_1 pulpcore-manager access-policy-views --url /pulp/api/v3/pulp_container/namespaces/ --userid 2

management command 'access-policy-views' is cli tool to introspect pulp rbac info for each viewset, in this case the '--userid 2' arg trys to test 'safe' viewset objects has_permission for the user in question.

userid=2 is 'alikins', a non-admin user in this galaxy_ng instance.

When it tries to introspect the 'retrive' action on the namespace viewset, it triggers the DRF errror:

AssertionError: Expected view ContainerNamespaceViewSet to be called with a URL keyword argument named "pk". Fix your URL conf, or set the `.lookup_field` attribute on the view correctly.

Output from the command including some DEBUG logging and full stack trace:
