#27089: commands/makemigrations.py runs MigrationLoader.check_consistent_history() for all database connections ----------------------------+-------------------- Reporter: aholmback | Owner: nobody Type: Bug | Status: new Component: Migrations | Version: 1.10 Severity: Normal | Keywords: Triage Stage: Unreviewed | Has patch: 0 Easy pickings: 0 | UI/UX: 0 ----------------------------+-------------------- In the file django/core/management/commands/makemigrations.py (line 97-100), an instance of MigrationLoader (loader) checks consistency on every database connection defined in settings.py.
{{{ for db in connection: connection = connection[db] if connection.settings_dict['ENGINE'] != 'django.db.backends.dummy': loader.check_consistent_history(connection) }}} The loader will then raise an InconsistentMigrationHistory exception for a connection whose migrations is not applied consistently, even if it's not to participate in the migration process. I didn't expect `makemigrations` would check connections that isn't to be migrated. Also, the error message "Migration xxx is applied before its dependency xxx" (line 285 in db/migrations/loader.py) didn't indicate checked connection. A more intuitive behavior would be to check only the connection that is to be migrated, or, if that isn't possible, include connection name in the error message. -- Ticket URL: <https://code.djangoproject.com/ticket/27089> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
