Hi,
I was looking for a way to customize the error message when trying to
submit an existing value for a unique field (using a ModelForm).
According to this request (http://code.djangoproject.com/ticket/8913),
I am not the first one to look for such a feature, and I'm happy to
wait for it.
My current solution is quite inelegant, though:
if register_form.errors.has_key('email') and (register_form._errors
['email'] == ['Customer with this E-Mail already exists.']):
register_form._errors['email'] = ErrorList(['My custom error message
goes here.'])
But I also found this snippet (http://www.djangosnippets.org/snippets/
1228/), and the first comment confused me. I never had to pass an
instance when instantiating the form - the is_valid() method created
the desired error message and linked it to the appropriate field.
Am I missing something?
Kind regards,
Jan
