Pass variables from url handler to the query set of a generic view

[jon@…]

If would be nice if you could pass variables from the url regexp in urls.py to the filter of a query set when using generic views.

(r'^/?(?P<person>\w+)/$', 'django.views.generic.list_detail.object_list', {'queryset': Item.objects.filter(name__name__iexact=person))

Currently, a statement similar to the following will fail with a NameError similar to the below:

NameError at /dave/
name 'person' is not defined
Request Method: GET
Request URL:    http://localhost:8000/dave/
Exception Type: NameError
Exception Value:        name 'dave' is not defined

The ideal behaviour would be that the filter function would be able to accept values from the url dispatcher.

This ticket arises from ​http://groups.google.com/group/django-users/browse_thread/thread/40c34ae87492d4dd/67cabff7abbbabe5#67cabff7abbbabe5 this discussion on django-users.

Maybe this?

queryset_func = lambda kwargs: Item.objects.filter(name__name__iexact=kwargs['person'])

(r'^/?(?P<person>\w+)/$', 'django.views.generic.list_detail.object_list', {'queryset_func': queryset_func})

The generic view would call queryset_func(kwargs) at runtime, with kwargs being the dictionary of parameters captured from the URL.

The solution here is to write a wrapper around the generic view.
