Question

Is there any easy way to assign class=radio to all elements whose widget is radioselect in a form ?
I know I can write such that

rb = forms.ChoiceField( widget=forms.RadioSelect(attrs='class':'radio'))

for all radio buttons in the form but I think there should be other ways. Because I probably use it for all radio buttons and it is not funny to write this for all.

You can create your own widget, like this:

class MyRadioSelect(forms.RadioSelect):

    def __init__(self, *args, **kwargs):
         attrs = kwargs.pop("attrs", {})
         if "class" in attrs:
             attrs["class"] = "%s radio" % attrs["class"]
         else:
             attrs["class"] = "radio"
         kwargs["attrs"] = attrs
         super(MyRadioSelect, self).__init__(*args, **kwargs)
