Say I have:
class A(models.Model):
...
class B(models.Model):
a = models.ForeignKey(A, unique=True)
...
I would like to show B field in A list_filter.
I've successfull show A fields in B list_filter with this patch:
http://code.djangoproject.com/ticket/3400
As I can't show a field in list_filter if it is not an attribute, I've
thought to create a dummy field in A model and use something like
"list_filter_range" in http://www.djangosnippets.org/snippets/587/
I think this filter implementation should be something like:
class BackwardRelatedFilterSpec(FilterSpec):
....
a_instance.b_set.all()[0]
...
but don't know how could be the concrete implementation.
Could anybody help me?
Last question: should I put a ticket with this question/feature at
django project?
Thanks a lot.
