Hello,

I was wondering how to use django to achieve the following application.
Suppose my articles are organized in categories, subcategories, and
subsubcategories. Database wise it will be good to have a category table
with a parent_id referring to itself. I don't know how to achieve this
by django database model, and also the __unicode__(self) function.

I'd appreciate if anyone can give me some hints about this issue.

Thanks,
Hai
