Hi, See this ticket for details on the error you are seeing: http://south.aeracode.org/ticket/407 If I understand correctly, it sounds like you're asking for something that isn't possible anyway. The id isn't known until the item is inserted into the database, because the database assigns the

Re: ManyToManyField('self') doesn't works as expect

By default many to many fields on self are symmetric[1], yours can't be (if A is up from B, B isn't up from A), so you need to specify symmetrical=False. You'll also need to specify some related names because they will clash. You might want to rethink your model though anyway, I'm not convinced
