I tested this with SQLite3 and it worked, using your models:
>>> a.users = User.objects.all()
>>> a.save()
>>> a.delete()
>>> a = AccountTypeA(name='aaaa')
>>> a.save()
>>> a.users = User.objects.all()
After that:
sqlite> select * from testapp_accounttype_users;
1|1|1
Which is what I should expect considering I have only one user and only one
account. Could you have an issue in another part of the code?
Regards,
Camilo.
