Hey there,
I'm trying to create a form with a "static" part (a "title" field, a "date"
field) and a variable part (these are "artist names", so that's a single
field that can be repeated multiple times, with a minimum of 1). I first
thought about the MultiValueField but it requires several fields, and in my
case I only want to use 1 field, just like an inline with one field in the
Django admin. I then tried to go with a Formset, but I wasn't able to set
it as mandatory (even if the field is marked as mandatory, if it's left
blank it's just like the form is not filled so the validation always
passes). Here's the code I tried for the formset part:
class ArtistForm(forms.Form):
name = forms.CharField(max_length=255, required=True)
ArtistFormSet = formset_factory(ArtistForm)af = ArtistFormSet({
'form-0-name': '',
'form-TOTAL_FORMS': u'1',
'form-INITIAL_FORMS': u'0',
'form-MAX_NUM_FORMS': u''})
assert False, af.is_valid()
In this case, is_valid() is always True. However if I a second field to my
form, that is required as well, and that only one of the two fields is
filled, the validation doesn't pass anymore.
I also thought of not using a form at all, but I should then check manually
if at least 1 "artist name" has been filled, and manage the errors manually.
I guess some people already implemented some "custom inlines" for the
frontend part of their websites. How did you manage to do that (with or
without Django forms)?
Thanks!
