copied!<p>Further research turned up the fact that the RadioSelect <code>renderer</code> can be <em>replaced</em>, and passed in as a parameter to the initial widget creation function. So I created my own renderer, and attached a list of Booleans, indicating which Radio buttons should be disabled.</p> <p>The renderer adds a <em>disabled</em> attribute to each Radio button widget as needed, then the <em>force_unicode</em> turns the widget's attributes into HTML that include a <code>disabled="True"</code> value.</p> <pre><code>from django.utils.safestring import mark_safe from django.utils.encoding import force_unicode class RandomRenderer(forms.RadioSelect.renderer): """ Modifies some of the Radio buttons to be disabled in HTML, based on an externally-appended Actives list. """ def render(self): if not hasattr(self, "actives"): # oops, forgot to add an Actives list return self.original_render() return self.my_render() def original_render(self): return mark_safe(u'<ul>\n%s\n</ul>' % u'\n'.join([u'<li>%s</li>' % force_unicode(w) for w in self])) def my_render(self): midList = [] for x, wid in enumerate(self): if self.actives[x] == False: wid.attrs['disabled'] = True midList.append(u'<li>%s</li>' % force_unicode(wid)) finalList = mark_safe(u'<ul>\n%s\n</ul>' % u'\n'.join([u'<li>%s</li>' % w for w in midList])) return finalList class OrderStatusForm(forms.Form): os = Order_Status.objects.values_list('id', 'status', 'reason') activeList = [True, False, True, False, True, False,] newStatus = forms.ChoiceField(widget=forms.RadioSelect( renderer=RandomRenderer), choices=os) newStatus.widget.renderer.actives = activeList </code></pre> <p>It's a little kludgy - I'm just sticking the <em>actives</em> list directly onto the renderer, which works (love Python's duck-typing), but would be cleaner if I passed the list in some constructors. Unfortunately I had problems with that, so took the easy way out. :)</p>
