Re: Executing DB-Queries during import

AppConfig.ready() is still at module-level.

It might be more appropriate to define an URL resolver (an object like django.conf.url)

that performs queries at resolve()/reverse() time instead.

A simpler solution could be to define a catch all view like django-cms does and

perform the routing inside the view.

Correct, module level queries should be avoided. Django might try to add some detection to warn about or prohibit that, see https://groups.google.com/d/topic/django-developers/7JwWatLfP44/discussion.

I understand db queries at module-level (aka "import time") should not happen.

When I am allowed to do db queries.

Is it advisable to execute db queries in my AppConfig ready signal handler?

Use case: I want to add URL patterns which get collected from db rows.
