Comment:
I am experiencing this issue with the 2.2.10 LTS release too:
{{{
class RowSelectorField(forms.fields.MultiValueField):
def __init__(self, *args, **kwargs):
choices = kwargs.pop('choice')
fields = [forms.fields.ChoiceField(),
forms.fields.IntegerField(required=False)]
super(RowSelectorField, self).__init__(require_all_fields=False,
fields=fields, *args, **kwargs)
self.widget = RowSelectorWidget(choices=choices)
def compress(self, values):
return values
}}}
all of the fields in HTML are set to required, even the integer field. I
have noticed if I change the super call to:
{{{
super(RowSelectorField, self).__init__(required=False,
require_all_fields=False, fields=fields, *args, **kwargs)
}}}
and in the MultiWidget I use:
{{{
class RowSelectorWidget(forms.widgets.MultiWidget):
def __init__(self, choices, attrs=None):
choices.append((len(choices), _('custom')))
widgets = [forms.RadioSelect(choices=choices, attrs={'required':
True}),
forms.NumberInput(attrs={'required': False})]
super(RowSelectorWidget, self).__init__(widgets, attrs)
}}}
I do get the correct expected behaviour.
