ModifiedPreorderTreeTraversalInAdmin
v1 v2 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. But, here it is mostly. 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.

Currently only works im postgesql and only tested in 8.1.

Just add fields to this and in should work. 4 5 Remember to set the TABLE variable at the top of models to appname_model. 4 6 5 7 Example using project name myproject and app name pages.
