Will I be able to use celery tasks during model migrations in Django?
I have a requirement to modify an existing db model called Alert and create new alerts with new functionality. I also need to take care of the existing alerts in the data base which were created with old model fields. After adding the new fields to Alert model, I'm trying to re-create the alerts with new functionality which has new columns. Basically taking existing rows and re-inserting them in data base with updated new columns with some extra information in the new columns. For this I'm trying to run a celery task in the function which is called as soon as the migration is applied. migrations.RunPython(function which does some operation and then run celerytask.delay(with_some_args) to create new alerts) I'm really concerned whether I can run a celery task inside the function which is passed to migrations.RunPython(). Even for testing this functionality, I don't have an existing data in our lower environment and the required migrations are already applied before even including this function. I don't want to mess with existing DB as everyone is using already. Can someone please confirm if I can actually run long running celery tasks when applying the migrations? in python manage.py migrate appname? Django: 1.11.15 … -
