   3 # Since the test database doesn't have tablespaces, it's impossible for Django
   4 # to create the tables for models where db_tablespace is set. To avoid this
   5 # problem, we mark the models as unmanaged, and temporarily revert them to
   6 # managed during each test. We also set them to use the same tables as the
   7 # "reference" models to avoid errors when other tests run 'syncdb'
   8 # (proxy_models_inheritance does).
