Question

I’ve got this urls.py :

urlpatterns = patterns('',

                   # Plugin actions
                   url(r'plugin/((?P<slug>[a-zA-Z0-9_\-]*)/)?$', PluginView.as_view(), name='wa-plugin'),
                   )

Then when I use reverse :

reverse('wa-plugin', args=[u'plugin-header-1'])

or even

reverse('wa-plugin', kwargs={'slug':u'plugin-header-1'})

I get

NoReverseMatch: Reverse for 'wa-plugin' with arguments 
'('plugin-header-1',)' and keyword arguments '{}' not found.

Do you have any ideas of how I can make it works ?

Answer 1

if the problem is the optional argument, one way around that is to define two url entries (to the same view):

urlpatterns = patterns('',
    # Plugin actions
    url(r'plugin/$', PluginView.as_view(), name='wa-plugin'),
    url(r'plugin/(?P<slug>[a-zA-Z0-9_\-]*)/$', PluginView.as_view(), name='wa-plugin'),
)

(pretty sure you can even use the same name, since they have different “signatures (kwargs)”)
