Now i know. The docs aren’t very clear on this part:

always use insert_at or move_to!

This is the only example I can recall seeing where someone showed an actual real world model using mptt. In your example, would not one also need to update the parent attribute as well after using move_to so that both methods would work afterward? Maybe something could be added to the model to automatically do move_to if the parent object changes…

I suppose that’s because the ‘lft’, ‘rgt’ fields (and the other ones MPTT creates by default for managing the hierarchy) are being created only in the superclasses… maybe the other django-tree framework does better in this respect [http://code.google.com/p/django-treebeard/] ?
Let me know how it goes!

Havn’t been able to get it working myself and looking around to see if anyone else has.
Abstract inheritance will work only if you want the child classes to only have parents in the same child class. Non-abstract inheritance doesn’t work at all.

This is where I got to:

Just starting with mptt and I think you saved me from a lot of frustration!
