Django 3.2 autocomplete_fields and DAL Conflicting

[selected-pixel-jameson]

When I upgrade to Django 3.2 (works fine on Django 3.1) I'm running into the error described in the link below. https://code.djangoproject.com/ticket/32659?cversion=2&cnum_hist=2

I've come to find that this error is not being generated by a Django AutoComplete Light field however, It is being generated by autocomplete_fields = [field_name] in the Django Admin.

My best guess is that there is some kind of conflict with the Django 3.2 updates and the Select2.js script.

I have a need to be able to use both Djangos autocomplete_fields as well as custom DAL AutoComplete queries.

I currently have DAL 3.8.2 installed.

Any insight into this issue would be very helpful. Thank you.

The same. DAL which is coming from django-taggit breaks django3.2 native autocomplete...

BTW the issue is appearing only when taggit & native autocomplete are on the same page.

[selected-pixel-jameson]

@Atorich That is not the case for me. I don't have taggit on the page in question, but it is installed.

This issue happens for me when I use DAL in conjunction with native django autocomplete. It's been fixed on this PR: https://github.com/yourlabs/django-autocomplete-light/issues/1239

It has been fixed in 3.9.0rc1 pip install https://github.com/yourlabs/django-autocomplete-light/archive/refs/tags/3.9.0rc1.tar.gz
