Hi all,
I see in docs.djangoproject.com/en/dev/ref/validators/ how to include
validators in a form field, but I have a field that needs to be
validated with a regular expression determined by another field.
Please help me call RegexValidator explicitly the right way. For one
thing, I don't see how to pass the field to the validator. For
another, I'm not sure exactly what to test for to determine that
validation failed. The code follows:
from django import forms
from django.core.validators import *
class IdentForm(forms.Form):
ident = forms.CharField()
ident_type = forms.ChoiceField(choices=(
('EIN','Employer ID'),
('SSN','Social Security Number'),
))
TYPE_CHOICES = (
('EIN','\d{2}-\d{7}'),
('SSN','\d{3}-\d{2}-\d{4}'),
)
def clean(self):
cleaned_data = super(IdentForm, self).clean()
ident = cleaned_data.get('ident')
ident_type = cleaned_data.get('ident_type')
regexp = TYPE_CHOICES[ident_type]
RegexValidator([regexp]) # What's missing?
# How do I pass ident to the validator?
if ??????: # Do I test for existence of error message?
ident = ''
return cleaned_data
What errors do I have?
Thanks.
