The join table is created by django when you do a syncdb, however if
the table with the M2M relation in it is already present (as in your
case) the join table will not be created. This appears to me to be
your problem. If you want it to be a m2m relation, you can create
the join table yourself or dump your data to a fixture, drop the
table and then sync the database again.
