I\'m using Django 1.2.4. I have a model that has a field that needs to be validated. When validation fails, I\'d like to display a custom error message to the user. Model editin
Without looking, it sounds like the admin is looking for an iterable as the value for field_name. Try:
field_name
raise ValidationError({'field_name': ["error message",]})
I think the admin expects any number of validation messages to be associated with each field on a form.
