Description
This is the code for ContentType.get_object_for_this_type:
self.model_class()._base_manager.using(self._state.db).get(**kwargs)
It forces the using of the contenttypes database for fetching the model and that can fail when the model only appears in the non-default database (where contenttypes ususally lives). Removing the .using clause fixes this.
This bug manifests in the admin "View on site" button that uses the contenttypes framework to redirect. A pull request is coming up.
