Hey Retro,
My boss managed to get this working so I can't take the credit but
this works and it's pretty useful. Basically, he's overriding the
widget renderer and making each "choice" a separate list item, giving
each "choice" it's own ID, making it much easier to use CSS to format
the choices individually (which is what I needed this for).
In the relevant forms.py:
class CustomRadioRenderer(forms.RadioSelect.renderer):
def __init__(self, *args, **kwargs):
super(CustomRadioRenderer, self).__init__(*args, **kwargs)
def render(self):
"""Outputs a <ul> for this set of radio fields."""
return mark_safe(u'<ul>\n%s\n</ul>' % u'\n'.join([u'<li id="li_
%s_%s">%s</li>'
% (w.attrs.get('id','radio'),w.index,force_unicode(w))
for w in self]))
In the form code that is returned to the view:
class myform(forms.ModelForm):
myfield = forms.IntegerField(widget = forms.RadioSelect(renderer =
CustomRadioRenderer, choices=Profile.MYFIELD_CHOICES))
Hope this helps you.
Cheers, R
