DetailView view looks for pk or slug by default but the error says id or slug.

[John Shimek]

With the following url rule

url(r'^{order/(?P<id>\d+)/$', DetailView.as_view(model=Order), name='order-detail')}

Django throws the following error:

Generic detail view order must be called with either an object id or a slug.

From django/django/views/generic/detail.py in get_object, line 45

It confused me for a bit because I am supplying the id of the object. Upon looking at detail.py, it looks for pk and slug. I checked the documentation and found that does mention pk and slug as well, so I am obviously doing it wrong. But, in my mind, id also makes sense. But whether support for id is added or not, I think the error message should be updated to say 'object pk or a slug'.

I am running 1.3 alpha at the moment, but I checked the method trunk it is the same.
