Look at it carefully; it works with *any* depth of categories.
To confirm, run this simplified example which uses plain Python
objects instead of models:
class Category(object):
def __init__(self, title, parent=None):
self.title = title
self.parent = parent
def __str__(self):
if self.parent:
return "%s -> %s" % (self.parent, self.title)
else:
return self.title
A = Category(title='A')
B = Category(title='B', parent=A)
C = Category(title='C', parent=B)
D = Category(title='D', parent=C)
E = Category(title='E', parent=D)
print A
print B
print C
print D
print E
You'll get this output:
A
A -> B
A -> B -> C
A -> B -> C -> D
A -> B -> C -> D -> E
Look carefully at that __str__ method to see why this works.
