My application needs to validate data from a from beyond the
validation of Fields done by django. So in my form handler, I check
Form.is_valid, and if that returns true, then I do my own validation.
In case of errors, I attach an error message to the field, e.g.
self.form.fields['foobar'].errors = 'some error message'
And then I redisplay the form. But the error message doesn't show up,
even though the template includes
{{ form.foobar.errors }}
And through logging I have confirmed that the errors attribute of the
field has been set, right before the render_to_response call
containing the form. I'm guessing that this has something to do with
the fact that the form already passed the is_valid check.
How can I force the form to become "invalid" again, once my own
validation detects errors?
