Additional example for reverse_lazy documentation

[Alasdair Nicol]

Hi,

I like the upcoming reverse_lazy in Django 1.4 (commit 16121). I suggest the examples should include using reverse_lazy in urlpatterns.

I just helped a user out in stackoverflow [1] who was struggling with NoReverseMatch errors because their url patterns used reverse for optional arguments. I think adding an example might stop users from struggling with the same problem in future.

My suggested one line addition to the examples in [2] is

 * providing a reversed url in a URL pattern as an extra argument to the view function.

On the other hand, I realise that the documentation is stating "some common cases", it doesn't have to be exhaustive.

I'd like to make a ticket and patch if people think this is a good idea.

Regards,
Alasdair Nicol

This is a good suggestion. Feel free to open a ticket. In fact, the
doc about reverse_lazy could be further improved by providing some
concrete code samples -- so if your patch contains some, all the
better ;-)
