Hi
I understand that but the problem is its a condition which i have to add if
the revisit checkbox is selected and then in interview_type dropdown None
option is selected ; after pressing save it should throw an error .
None is an option in the dropdown . It is not blank=True and null =True
INTERVIEW_TYPES = (
('default', 'None'),
('Paired Visit','Paired Visit'),
('Time Series', 'Time Series'),
),
interview_type will show choices with dropdown 1) None 2) Paired Visit 3)
Time Series
