Re: Category list in Django

[Bro]

Big thanks to Matthias and everyone that help me a lot.

To correct this error, I get the last Django and Django-mptt trunk.
The error is gone :)

Looks like it's time to update your Django installation.

Re: Category list in Django

[Bro]

I use this sample code :

from django.db import models

   import mptt

   class Genre(models.Model):
   name = models.CharField(max_length=50, unique=True)
   parent = models.ForeignKey('self', null=True, blank=True,
related_name='children')

   mptt.register(Genre, order_insertion_by=['name'])

But Django send me this error :

in register dispatcher.connect(pre_save,
signal=model_signals.pre_save, sender=modem)
AttributeError: 'module' object has no attribute 'connect'

You have the documentation at:

http://django-mptt.googlecode.com/svn/trunk/docs/models.txt

mptt will give you lots of extra messages to deal with the category tree.
