Reversing Django URLs With Extra Options
- by Justin Voss
Suppose I have a URLconf like below, and 'foo' and 'bar' are valid values for page_slug.
urlpatterns = patterns('',
(r'^page/(?P<page_slug>.*)/', 'myapp.views.someview'),
)
Then, I could reconstruct the URLs using the below, right?
>>> from django.core.urlresolvers import reverse
>>> reverse('myapp.views.someview', kwargs={'page_slug': 'foo'})
'/page/foo/'
>>> reverse('myapp.views.someview', kwargs={'page_slug': 'bar'})
'/page/bar/'
But what if I change my URLconf to this?
urlpatterns = patterns('',
(r'^foo-direct/', 'myapp.views.someview', {'page_slug': 'foo'}),
(r'^my-bar-page/', 'myapp.views.someview', {'page_slug': 'bar'}),
)
I expected this result:
>>> from django.core.urlresolvers import reverse
>>> reverse('myapp.views.someview', kwargs={'page_slug': 'foo'})
'/foo-direct/'
>>> reverse('myapp.views.someview', kwargs={'page_slug': 'bar'})
'/my-bar-page/'
However, this throws a NoReverseMatch exception. I suspect I'm trying to do something impossible. Any suggestions on a saner way to accomplish what I want?
Named URLs aren't an option, since I don't want other apps that link to these to need to know about the specifics of the URL structure (encapsulation and all that).
