Make BoundField with RadioSelect widget iterable

[oyvind]

Would allow

{{ form.boundradiofield.0.choice_label }} {{ form.boundradiofield.0.tag }} possible in the tamplate

See tests for example

Hello,

In this method:

    def __iter__(self):
        data, attrs = self.get_data_and_attrs(widget, attrs)
        for i in self.field.widget.iter(self.html_name, data, attrs=attrs):
            yield i

where are the initial widget and attrs supposed to come from?

This patch solves the issue in my last comment and also ads value indexing.

This is somewhat of a separate issue, but I would like to see a boundfield.get_data() method and a separate bountfield.get_widget_and_attrs() method.

Marking as a dupe of the more recently patched in #9230
