Question

I have this in URL file

(r'^new/(?P<object_class>\w+)/(?P<action>\w+)/(?P<object_id>\d+)/$', create_object)

NOw for URL like /new/book/edit/5 it is working fine

But if i do /new/book/create then it says nor URL matched.

Is it possible that third argumrent is optional so that i can use one URL rule for above cases

Answer 1

(r'^new/(?P<object_class>\w+)/(?P<action>\w+)/((?P<object_id>\d+)/)?$', create_object)

This should do it. (Notice I wrapped object_id and the / in a (..)? to make it optional)

Now object_id should be none in the view.
