detype_pattern function doesn't support class django.urls.resolvers.LocalePrefixPattern

[fpoisson35]

Hello,

I'm trying to validate my spectacular configuration with the CLI like this :
python manage.py spectacular --color --validate --fail-on-warn --api-version v1

And i have this warning:
Warning: unexpected pattern "en/" encountered while simplifying urlpatterns.

When i search it seems that this is due to function detype_pattern which tests different class of pattern but not LocalePrefixPattern.

How could i change my configuration to resolve this warning ?

Thanks,
Regards,

Hi,

can you state an example to make this easier to reproduce? How are you using LocalePrefixPattern and how does the full path look like?

Seems like a bug, so we need to fix this and there is probably nothing you can do with the configuration alone (except for not using LocalePrefixPattern 😄 )

Hi,

We are using this import inside urls.py, which permit to insert our pattern with i18n_patterns:

from django.conf.urls.i18n import i18n_patterns

urlpatterns += i18n_patterns(
    path("accounts/", include("django.contrib.auth.urls")),
    path("admin/", admin.site.urls),
    path("", include("dashboard.urls")),
    ...

This is the function i18n_patterns which initialize LocalePrefixPattern, and the path presented with show_urls is like this :

/en/ dashboard.views.HomeView dashboard:home

Inside settings we have USE_I18N = True and LANGUAGES = (("en", _("English")), ("fr", _("French")))

Thanks in advance for your help !

Regards
