[1.7.x] Fixed #23699 -- Prevented flush from loading initial data for apps with migrations.

            # Reinstall the initial_data fixture.

            if options.get('load_initial_data'):

                # Reinstall the initial_data fixture.

                call_command('loaddata', 'initial_data', **options)

                # Reinstall the initial_data fixture for apps without migrations.

                from django.db.migrations.executor import MigrationExecutor

                executor = MigrationExecutor(connection)

                app_options = options.copy()

                for app_label in executor.loader.unmigrated_apps:

                    app_options['app_label'] = app_label

                    call_command('loaddata', 'initial_data', **app_options)

        else:

            self.stdout.write("Flush cancelled.\n")

* Warn for duplicate models when a module is reloaded. Previously a

RuntimeError was raised every time two models clashed in the app registry.

(:ticket:`23621`).

* Prevented :djadmin:`flush` from loading initial data for migrated apps

  (:ticket:`23699`).
