Re: Forms - Widget - Radioselect - how to set initial value on a static form

Karen's suggestion is great. You can also pass initial data into the
form constructor. So using the example above if you do (in your view):

my_form = F1(initial=dict(rs_field='N'))

you'll achieve the same result. Don't think there's much to be said
for either way other the way I just suggest might allow you a bit more
flexibility if you want something in the view to dictate the initial
value.
