I'm hoping to get a sanity check for how I'm using the clean method.
I'm using new forms and I wanted to do a sanity covering the
relationship of two different fields. The form as auto created with
form_for_instance and friends was just fine, I just needed a "clean()"
method of my choosing. I got something working (after trying several
very hacky things) and here is the least hacky thing I ended up with.
Still seems a little weird to me for some reason. I'd just like some
advice on whether this is how it's designed to work or if I'm still
missing something.
class LabOrderForm(forms.BaseForm):
def __init__(self, *s, **kw):
forms.BaseForm.__init__(self, *s, **kw)
def clean(self):
index_number = self.cleaned_data.get('index_number')
nih_contract_code = self.cleaned_data.get('nih_contract_code')
if index_number:
if (index_number.contract_type == 'nih' and not
nih_contract_code or
index_number.contract_type != 'nih' and
nih_contract_code):
raise forms.ValidationError('all nih contracts (and
only nih contracts) must have an associated contract number')
return forms.BaseForm.clean(self)
This can then be instantiated with:
forms.models.form_for_instance(original_laborder, form=LabOrderForm)
Is there a more django-esque to get a custom clean method for an auto-
generated form like this or is this the way it's supposed to go?
Also it seems that newforms doesn't respect the validator_list in the
model, is that correct? As designed?
thanks
