I added to my code a autocomplete field in the ModelAdmin class of a model
name UserData
Code is pretty simple:
{{{
@admin.register(UserData)
class UserDataAdmin(admin.ModelAdmin):
list_display = ("fiscal_code", "company", "surname", "name")
fields = ["company", "name", "surname", "fiscal_code", "address",
"identity_document"]
# FIXME: autocomplete does not work in Django 3.2.X. Downgraded to
3.1.X
autocomplete_fields = ["company"]
}}}
The interface shows "The results could not be loaded" and console shows
the following errors:
{{{

The issue is the same of ticket
[https://code.djangoproject.com/ticket/32659] and it is still not resolved
in version 3.2.9.
Downgrading to version 3.1.13 resolves the issue and autocomplete fields
work as expected.
The previous ticket was closed with no solution. There is no issue with
multiple url definition in my case, downgrading is a workaround but the
last LTS version of Django is 3.2.X and here the bug is present.
If the issue is a configuration problem, please give an hint on the
solution.
If not, please manage the ticket accordingly.
