Don't mix *args and **kwargs in call to reverse()!

[Adrián Ribao]

Change in rev:8760 introduced this exception: "Don't mix *args and
**kwargs in call to reverse()!"

-- django/trunk/django/core/urlresolvers.py --
...
def reverse(self, lookup_view, *args, **kwargs):
if args and kwargs:
raise ValueError("Don't mix *args and **kwargs in call to
reverse()!")
...
Why is not possible to mis args and kwargs? I don't understand the
reason, and all of my reverse funcions will fail because of this.

I'd like some help with this.

Thank you.

I'll write an example of the problem. All my urls are prepared
following the best SEO rules, so in many places I have urls like:
(r'^(.*)-f(?P<id>\d+)\.html$','view_photo')

this would make the url:
my-photo-f2.html

I get the url using:
reverse('app.views.view_photo', args=[slugify(photo.title),],
kwargs={'id':id} )
(Note: I don't want to use a slug field.)

Now this won't work. Well, IMHO this is a bug, I don't see the point.
Besides this makes rev:8760 backwards incompatible and it wasn't
suppose to.

I really need some more information about this.

Thank you.

I just hit this too. There seems to be no information or hint in the
docs about this (neither in the docs about reverse or permalink), from
what I can find...
