Question

Here is the problem, the urls.py file in a django project look like this:

urlpatterns = patterns('',
    ...
    url(r'^admin/', include(admin.site.urls)),
    url(r'^testapp/', include('testapp.urls')),  #Here is the problem.
)

And I got an app installed, it is called ‘testapp’, so I wrote the include('testapp.urls') in the patterns.

The problem is that, Why should I put the testapp.urls in the quotation marks?
Cuz I tried to put it like this: url('r^testapp/', include(testapp.urls)), it didn’t work.
Why?

Answer 1

Your must import app in urls.py

import testapp

urlpatterns = patterns('',
    ...
    url(r'^admin/', include(admin.site.urls)),
    url(r'^testapp/', include(testapp.urls)),
)
