Description (last modified by Malcolm Tredinnick)

If there are multiple patterns matching the same view function, it seems like, only the first match is considered.

Lets say a function has an optional "id" parameter which defaults to None and below is the patterns pointing that function.

(r'^(?P<slug>[-\w]+)/$', views.myfunc),

(r'^(?P<slug>[-\w]+)/(?P<id>\d+)/$', views.myfunc),

In that case,

{% url views.myfunc slug=something,id=someint %}

fails to match anything, where we can expect it to match the second
pattern and return "/something/someint/"

oops... clicked the wrong box. Meant to change it to "accepted" not take assignment. Ah well ... I'm not working on this one, folks, so somebody else should feel free. :-)

This was fixed by the introduction of named URL patterns, which provide a way to differentiate multiple patterns using the same view function.
