Validators come in two varieties: those linked to field definitions in
models and those that linked to field definitions in custom manipulators.
With first kind you can't get the object's id. They just deal with plain
data.
The second kind is more flexible since you can write your manipulator as
you like it. For example:
class MyManipulator(MyModel.ChangeManipulator):
def __init__(self, object_id):
MyModel.ChangeManipulator.__init__(self, object_id)
# add new validator to some field's validators
fields[2].validator_list.append(self.validate_field)
def validate_field(self, data, all_data):
self.original_object # this is the object
The main disadvantage of this approach is that you can't use it with
generic views since they won't use your custom manipulator.
I remember that some was trying to solve this problem on this list but
don't remember results of the effort.
