I have two text input fields in a form. At least one of them is
required. My question is, how can I check for this?
class MyManipulator = (formfields.Manipulator):
def __init__(self, request=None):
self.fields = [
formfields.TextField(
field_name='apples',
length=5,
),
self.fields = [
formfields.TextField(
field_name='pears',
length=5,
),
]
The problem is, I cannot use is_required=True. I can use another field
and make it is_required=True and define another validator - this is
what I'm doing now:
....
self.fields =
.....
formfields.TextField(
field_name='basket',
length=5,
is_required=True,
validator_list=[apples_or_pears],
),
....
def apples_or_pears(self, field_data, all_data):
if not all_data.get('apples', '') and not
all_data.get('pears', ''):
raise validator.ValidationError, _('bummer - what
now?')
....
This is a hack and has several drawbacks, such as it does not belong to
the correct field, and is within an unexpected field's validator list.
Thank you for your suggestions.
