Description (last modified by Greg Kaleka) ¶

In Django 4.1, the admindocs ViewDetailView raises an AttributeError. I'm not clear on why _active is missing the local_value attribute when _is_callback is called.

Reproduction steps:

Create a new project with Django 4.1
Include django.contrib.admindocs in your installed apps
Add the urls to your urlconf: path("admindocs/", include("django.contrib.admindocs.urls"))
Run manage.py migrate and manage.py createsuperuser
Go to localhost:8000/admindocs/views/ and click on any view to go to the ViewDetailView

Quick and dirty fix in django/contrib/admindocs/utils.py:

Code highlighting:

def _is_callback(name, urlresolver=None):
    if not hasattr(_active, "local_value"):
        _active.local_value = _callback_strs
    if urlresolver and not urlresolver._populated:
        register_callback(urlresolver, _active.local_value)
    return name in _active.local_value
