In my project I am using django-mptt for categories.
My model:
class Category(models.model):
name = models.CharField()
parent = models.ForeignKey
When defining the model you can specify the ordering with "order_insertion_by".
So something like this:
class Category(MPTTModel):
name = models.CharField()
parent = models.ForeignKey("self", blank=True, null=True,
related_name="sub_category")
class MPTTMeta:
order_insertion_by = ['name']
Then you can rebuild your database with Category.tree.rebuild()
which should respect the ordering specified.
