Hi James et all,
Because of what I want it isn't possible to just rely on a validator, I
need a manipulator to get a request object.
The manipulator only has to add an extra validator to one field. This
validator validates using the database. No custom form is needed. The
manipulator will be use

You don't need to write a manipulator; just write a validator
function, and put it in the validator_
Hmm,
I wrote this in my models.py. Errors rased are just for debugging.
class HasUniquePath(object):
def __init__(self, cat_obj, error_message=gettext_lazy("No unique
path!")):
self.cur_cat = cat_obj
self.error_message = error_message
self.always_test = True
def __call__
Thanks James,
I'll try this one
def IsUniqueForPath():
...
class Category(models.Model):
...
parent = models.ForeignKey('self', blank=True, null=True,
related_name='child_set', validator_list=[IsUniqueForPath])

Hi James,
When I write a custom validator like: isValidCategory() I need a
manipulator, validator and a form. Is there a way to use the 'current'
ones and to expand these or do I need to create them from scratch?

This code needs to be a custom validator attached to the field, rather
than being in the 'save' method; once you're at the point
