def test_alter_index_together(self):
        project_state = self.set_up_test_model()
        operation = migrations.AlterIndexTogether('Pony', [('pink', 'weight')])
        new_state = project_state.clone()
        operation.state_forwards('tests', new_state)
        self.assertIndexNotExists('tests_pony', ['pink', 'weight'])
        with connection.schema_editor() as editor:
            operation.database_forwards('tests', editor, project_state, new_state)
        self.assertIndexExists('tests_pony', ['pink', 'weight'])
        with connection.schema_editor() as editor:
            operation.database_backwards('tests', editor, new_state, project_state)
        self.assertIndexNotExists('tests_pony', ['pink', 'weight'])
