I think you're being confused by the display of what's being returned. In fact the value in cleaned_data should be the actual *model instance*. Since you have __unicode__ defined on that model, when you do >>> value = myform.cleaned_data['mychoicefield'] >>> print value you will see the value of the unicode method you defined. But the underlying value is the actual element - you can do >>> print value.id to get the id, and so on. By the way, I haven't addressed the second part of your OP, which was how to dynamically filter the values in the choicefield according to session data. Here's a good post that explains that: http://oebfare.com/blog/2008/feb/23/changing-modelchoicefield-queryset/ -- DR. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
