Django: namespace isn't unique

In Django 1, I used to have the following URL mappings:

...
url(r'^main/', include('main.urls', namespace='main')),
url(r'.*', include('main.urls'))

The r'.*' mapping is always at the last line to take care of all kinds of URLs not mapped.

In Django 2, the following mappings are used instead:

path('main/', include('main.urls', namespace='main')),
re_path('.*', include('main.urls')),

Although it also works, yet Django complains:

?: (urls.W005) URL namespace 'main' isn't unique. You may not be able to reverse all URLs in this namespace

Giving the second mapping another namespace is not working. Any solutions?

In that case you can use django.views.generic.base.RedirectView to simply redirect to the said url without importing it twice. 

urlpatterns = [
    path('main', include('main.urls')),
    re_path('.*', RedirectView.as_view(url='main/your_default_url_in_main_url'), name='main'),
]

Try to remove the trailing slash of 'main/' and change to 'main'.

Note: If your main.urls looks like this

urlpatterns = [
    path('/whatever1', view1), 
    path('/whatever2', view2), 
]

You have to pick where to redirect the default view by supplying RedirectView.as_view(url='main/whatever1') to redirect to view1 as default. use 'main/whatever2' to redirect to view2 as default

try writing a view to redirect to main/ and then include the view in your urls:

re_path('.*', views.redirect_view)
