Public bug reported:

As models and migrations don't have any logical relation in code, so
differences are possible. Furthermore in most of cases differences
exists. The only way to solve this problem is using of specific test
such as this https://review.openstack.org/#/c/74081/  .

This is a diff example form Keystone:

AssertionError: Models and migration scripts aren't in sync:
[ [ ( 'modify_nullable',
      None,
      'federation_protocol',
      'mapping_id',
      { 'existing_server_default': None,
        'existing_type': VARCHAR(length=64)},
      True,
      False)],
  [ ( 'modify_nullable',
      None,
      'region',
      'description',
      { 'existing_server_default': None,
