Comment (by KyleMac):
My issue is that I wanted to use custom filters to change the titles of
filters to clarify their purpose. However you can't do this with filters
that span relationships because of the subject of this ticket.
There is currently no other way to change the title of a filter other than
using `verbose_name` on the field itself but that has a much wider effect.
What I was trying to do was something like the following:
{{{
class PastSupplierFilter(RelatedFieldListFilter):
def __init__(self, *args, **kwargs):
super(PastSupplierFilter, self).__init__(*args, **kwargs)
self.title = _('past supplier')
class ReorderAdmin(admin.ModelAdmin):
list_filter = (
('product__suppliers', PastSupplierFilter),
)
}}}
A better solution but a more complex change would be to allow
`list_filter` to accept a third value as the title of the filter. Django
currently assumes that the name of a field and the purpose/effect of a
filter are the same, which is not always the case especially when spanning
relationships.
