Hi,
I've hacked my way into the admin filters, changing the
RelatedFilterSpec from a single-select filter to a multi-select filter.
I can now filter on multiple values from the same ManyToMany or
ForeignKey relationship, i.e. if I add 'groups' to the list_filter for
Users, I can select all users
If I have a models file
class City(models.Model):
# ...
class Person(models.Model):
# ...
hometown = models.ForeignKey(City)
class Book(meta.Model):
# ...
author = models.ForeignKey(Person)
then select_related will allow me to easily find all persons and citys
related to a

Well, considering that Django explicitly advertises zero support for
this situation, I'd say getting *anything* to work is p
if you specify one of the fields to be the primary key, you would
probably violate the constraint (PK must be unique on itself)... It
would not work as a many-to-many:
1,2
2,2
2,1 -- couldn't do that, violates PK

This indicates that you could simply ignore the problem and add a
composi
What you describe is a ManyToManyField in disguise. A thinly veiled
disguise. Perhaps you might want to rethink what you actually need.
Be carefull not to think too much within the frame of Rational
Databases.

You'll probably want to read this and save yourself some time:

Hi,
I need to be able to use models like this:
class Xlwzl(models.Model):
xl = IntegerField(primary_key=True)
wzl = IntegerField(primary_key=True)
(they are actually ForeignKeys, but this probably doesn't matter.
This is probably also a good start for ManyToManyFields with an
