New description:
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+)/$',
'django.views.generic.list_detail.object_list', {'queryset':
Item.objects.filter(name__name__iexact=person))}}}
Currently, a statement similar to the following will fail with a NameError
similar to the below:
{{{
NameError at /dave/
name 'person' is not defined
Request Method: GET
Request URL: http://localhost:8000/dave/
Exception Type: NameError
Exception Value: name 'dave' is not defined
}}}
The ideal behaviour would be that the filter function would be able to
accept values from the url dispatcher.
This ticket arises from [[http://groups.google.com/group/django-
users/browse_thread/thread/40c34ae87492d4dd/67cabff7abbbabe5#67cabff7abbbabe5
this]] discussion on django-users.
Comment (by adrian):
Maybe this?
{{{
#!python
queryset_func = lambda kwargs:
Item.objects.filter(name__name__iexact=kwargs['person'])
(r'^/?(?P<person>\w+)/$', '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.
