Can't get error to display when using inlineformset_factory.

[Andrew Michael]

I am trying to get validation errors to appear on my web page when using an inlineformset_factory. I have a main form called PersonalInformation form and 3 inline forms (Relative, PositionHeld and Phone). I am receiving the main form errors on my page, but I can't get the 3 inline forms to display the errors. 

Do I need to write custom errors? 

Can anyone help? I have searched on Google and tried several different things with no luck.

Thanks.

Try using

 

self.add_error('state': 'Must select state if province is not entered.')

 

or

raise ValidationError({'state': 'Must select state if province is not entered.'})

Thanks for your response, Matthew, however the problem that I am experiencing is with the inline fields not returning an error message. In the form.py file, self does not have the inline fields available to return an error when performing a check on the value. 

For example: for phone_formset, I need to write an error check that says if a phone type is selected, then a phone number must be entered. 

What should the code look like and where should it be included?
