Thanks for answer. You have reason, I don't need do that. With a clean method in the modelform is enough. This question appear, because initialy I just wanted add a validator to the field of the model, but for the validation the parameter "self" was necessary and I could not find a way to pass this parameter. However I don't need this, with a clean method in the form, I can solve this quickly.
