Multiple ManyToMany relationships

[benbc]

Hi

I'm having problems with multiple ManyToMany relationships between two
models.    I don't see all the methods I expect for navigating between
them.  I'm using revision 698, checked out a few days ago.

Here are the models:

from django.core import meta
class Group(meta.Model):
    name = meta.CharField(maxlength=20, unique=True)
class User(meta.Model):
    name = meta.CharField(maxlength=20)
    groups = meta.ManyToManyField(Group, blank=True,
related_name='member',
        singular='group_membership', verbose_name='Group memberships')
    groups_owned = meta.ManyToManyField(Group, blank=True,
        related_name='owner', singular='group_ownership',
        verbose_name='Group ownerships')

And here are the objects that I get from them (with special members
stripped out):

>>> from django.models.demo import *
>>> dir(groups.Group(name='cheese makers'))
['_meta', 'delete', 'get_member', 'get_member_count',
'get_member_list', 'id', 'name', 'save', 'set_users']
>>> dir(users.User(name='bob'))
['_meta', 'delete', 'get_group_membership_list',
'get_group_ownership_list', 'id', 'name', 'save', 'set_groups',
'set_groups_owned']

The User object provides the methods that I'd expect, but Group
doesn't.  I'd expect get_owner, get_owner_count and get_owner_list in
addition to the get_member_*.  Also I'd expect to see set_owners and
set_members instead of the single set_users.

Any idea what the problem is here?  Should I raise a bug ticket?

Thanks
Ben
