Question

I have a simple url that doesn’t match into one of my applications (plaq)

main url.py:

urlpatterns = patterns('',
  #...
  url(r'^content/', include('content.urls')),
  url(r'^$', include('content.urls')),
  url(r'^plaq/', include('plaq.urls')),
  #...
)

plaq url.py:

urlpatterns = patterns('',
  (r'^$', pres),
  (r'pres^$', pres),
  (r'about^$', about),
  (r'privacy^$', privacy),
)

Trying to access to my_host/plaq/pres gives me

Using the URLconf defined in my_project.urls, Django tried these URL patterns, in this order:
…
12. ^content/
13. ^plaq/ ^$
14. ^plaq/ pres^$
15. ^plaq/ about^$
16. ^plaq/ privacy^$
…
The current URL, plaq/pres/, didn’t match any of these.

While my_host/plaq displays the good pres view

Why can’t I access to my_host/plaq/pres ?

Answer 1

Firstly, you need to learn a bit about regexes: ^ means beginning of string, but for some reason you have it at the end.

Secondly, your URLs end in slashes, so your urlconfs must too.

urlpatterns = patterns('',
  (r'^$', pres),
  (r'^pres/$', pres),
  (r'^about/$', about),
  (r'^privacy/$', privacy),
)
