Comment (by anonymous):
Although the above is not a true bug, it is something that's difficult to
work with and non-intuitive. So consider this a vote for a new feature
request. The root problem is not configuration of the admin interface, it
is that if you use the "through" parameter it assumes you have additional
data that needs to be added. This is rarely the case in a legacy database
situation.
There are a couple possible solutions:
1. Have the ORM inspect the through model and find the correct foreign key
fields to make normal manytomany functionality work (like add() or admin
forms).
2. Allow two more optional parameters (or a tuple or something), to allow
manually naming the foreign key fields.
This would allow a legacy m2m behave like a native one when there's no
additional data (which is most of the time). I work in a corporate setting
where getting django to connect to "legacy" data (any database not created
by django) is indispensable, and this will only become more common when
the multi-db branch lands in the trunk.
