Hi all, I figured out how it works.
Using MultiWidget requires three components: MultiWidget, MultiValueField
and a form.
Here is my example:
class ComplexMultiWidget(forms.MultiWidget):
def __init__(self, attrs=None):
widgets = (
forms.DateInput(),
forms.Select(choices=(('D', 'Days'),
('W', 'Weeks'),
('Y', 'Years'))),
)
super(ComplexMultiWidget, self).__init__(widgets, attrs)
def decompress(self, value):
if value:
data = value.split(',')
return [data[0], data[1]]
return [None, None, None]
def format_output(self, rendered_widgets):
return u'\n'.join(rendered_widgets)
class ComplexField(forms.MultiValueField):
def __init__(self, required=True, widget=None, label=None, initial=None):
fields = (
forms.DateField(widget=forms.DateInput),
forms.ChoiceField(choices=(('D', 'Days'),
('W', 'Weeks'),
('Y', 'Years'))),
)
super(ComplexField, self).__init__(fields, required,
widget, label, initial)
def compress(self, data_list):
if data_list:
return '%s,%s' % (data_list[0],''.join(data_list[1]))
return None
class ComplexFieldForm(forms.Form):
field1 = ComplexField(widget=ComplexMultiWidget())
I took the solution from here: http://stackoverflow.com/a/2387330
I hope this help someone in the future!
