2211	[patch] exact, gt, gte, lt, lte, ne lookups fail for DateField fields	paolo@…	Adrian Holovaty	"Documentation about field lookups cites this example: {{{ Entry.objects.filter(pub_date__lte='2006-01-01') }}}

However, if pub_date is a !DateField field the query fails. Same thing with exact, gt, gte, lt, lte, ne lookups.
Using {{{ Entry.objects.filter(pub_date__lte=datetime.date()) }}} all works fine, though I don't think this is the intended way to make this kind of query.

In the admin site also there are some troubles caused by this behaviour. Try to add a !DateField field in list_filter for some model and ask for objects in 'Past 7 days'.

This is the traceback.
