Comment (by aaugustin): Replying to [comment:23 akaariai]: > We can get rid of the delete cascade problem - any model outside currently available apps should be empty, so cascading to those models should not do anything in any case. But the truncate cascade problem is harder. PostgreSQL won't let you truncate a table if all dependant tables aren't truncated in the same query, even if those dependant tables are empty. We can either use TRUNCATE CASCADE (but this can cascade to models outside of Django's control), or the current logic of expanding cascades. I thought requiring every related app to be in `available_apps` solved this problem? I wanted to document it like this: https://github.com/aaugustin/django/commit/4717a1e If the trade-off is "a few more apps in available_apps" vs. "logic for expanding cascades", I'm choosing the first one :) As far as I can tell, for Django's own test suite, we don't have the problem because we don't have inter-app FKs, do we? -- Ticket URL: <https://code.djangoproject.com/ticket/20483#comment:25> 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.
