python - Django: Display a custom error message for admin validation error -


i'm using django 1.2.4. have model has field needs validated. when validation fails, i'd display custom error message user. model editing done in admin interface.

this i'm doing currently:

def clean_fields(self, exclude=none):     # validation     if problem:         raise validationerror({'field_name': "error message"}) 

unfortunately, print out separate validation message on admin page each character in value of field_name.

what proper way signal error message want?

without looking, sounds admin looking iterable value field_name. try:

raise validationerror({'field_name': ["error message",]}) 

i think admin expects number of validation messages associated each field on form.
