With the update ==3.14.0 -> ==3.15.0, ModelAdmin must define "search_fields"

[i-huzaifa-arshad]

Recently upgraded to v3.15.0 and unable to run the server ./manage.py runserver or ./manage.py migrate. I get the error:

django.core.management.base.SystemCheckError: SystemCheckError: System check identified some issues:

ERRORS:
<class 'rest_framework.authtoken.admin.TokenAdmin'>: (admin.E040) ModelAdmin must define "search_fields", because it's referenced by TokenAdmin.autocomplete_fields.

System check identified 1 issue (0 silenced).

I tried to create a custom admin class in my admin.py file but it still gave me this error.

The only thing worked for me was to open the .venv/lib/python3.12/site-packages/rest_framework/authtoken/admin.py and inside the TokenAdmin, commenting or deleting the autocomplete_fields.

class TokenAdmin(admin.ModelAdmin):
    ...
    search_fields = ('user__username',)
    search_help_text = _('Username')
    ordering = ('-created',)
    actions = None  # Actions not compatible with mapped IDs.
    # autocomplete_fields = ("user",)

    def get_changelist(self, request, **kwargs):
        return TokenChangeList
   ...

How to address this issue properly? I can't do this manual commenting out the package class variable.

Any help is appreciated.

Duplicated of #9300

Well, it was not kind of duplicated of #9300 as my error code is different. But thanks, somehow the issue is temporarily fixed.
