I would like to utilize the built-in Page content model "Form" and be able
to intercept posted form data via a Page Processor to perform custom
validation on it.
I know you can return a dictionary with extra response content, but I'm at
a loss at how to force an "invalid" form submission.
In the example below, there is a Page slug with "rsvp" and it has a Form
content model with a bunch of fields.
I'd like to do something like this which would be able to invalidate the
form and prevent it from submitting successfully.
@processor_for('rsvp')
def rsvp_form(request, page):
if not request.POST.get('something'):
return {'errors': 'tons of them'}
return {}
Is that something that's possible?
