ModifiedPreorderTreeTraversalInAdmin
v2 v3 1 Looking at the mptt example [http://code.djangoproject.com/wiki/ModifiedPreorderTreeTraversal] it seemed a bit complicated for a normal user to understand. So i made my own, but considering i cannot group by makes aggregate functions hard (impossible?) to make this work nice, but magic-removal made it easier. Currently only works i mpostgesql and only tested in 8.1. Use at will and own RISK, but if/ when you improve it i would like to see it made available.1 Looking at the mptt example [http://code.djangoproject.com/wiki/ModifiedPreorderTreeTraversal] it seemed a bit complicated for a normal user to understand.
