url() is deprecated in Django 3.1+

[coofercat]

For anyone else looking for how to make this work in Django 3.1+, you'll find that url() is deprecated, so where you see this in the documentation:

url(r'^local_proxy/(?P<url>.*)$', LocalProxy.as_view(), name='proxy')

...change it to this:

path('local_proxy/<path:url>', views.LocalProxy.as_view(), name='proxy'),

(you could also use re_path(), but there's really no need)

I hope this helps someone out :-)

Thanks. We need to drop unsupported django versions to fully resolve the confusion (which will let us remove url() entirely from docs, samples).

I'll leave this open for visibility until that happens.

I have proposed a way to maintain the compatibility and using re_path instead of url. We can maintain compatibility with older version of django

# The django url function is deprecated as of django 3.1
# We use its equivalent re_path to maintain compatibility
# with older versions of django
try:
    from django.urls import re_path
except ImportError as exception:
    from django.conf.urls import url as re_path
