Hey @ngnpope 👋 Don't suppose I could ask for your opinion here could I please? 🎁

https://github.com/carltongibson/django-filter/commit/b035bf278ac82254022b639a0a1b08ae66a445a3 is needed to surface the ChoiceIterator issue, otherwise we hit apps not loaded setting up the test run.

This only comes up in tox. (Grrr.) Calling django.setup() is unobjectionable, and probably should have always been there… 🤔, so unless someone wants to input I'm just going to leave it.

Hey @ngnpope 👋 Don't suppose I could ask for your opinion here could I please? 🎁

Will take a look... 👀

[ngnpope]

See #1607 for an alternative 🙂

[carltongibson]

Thanks @ngnpope 🦸‍♀️ Looks good. I'll give it a proper read over the weekend. 🎁

Closing in favour of #1607
