dynamic forms in django

i've built my own dynamic form, kind of following james bennetts example. using the following lines in forms.py

def make_question_form(request):
fields = { 'venue' : forms.CharField(widget=forms.HiddenInput()),
           'survey' : forms.CharField(widget=forms.HiddenInput())}
return type('Question_Form',(forms.BaseForm,), { 'base_fields': fields })

and the following in the view to build it (I know its not truely dynamic, i plan to add the dynamics next.

question_form = make_question_form(request)
question_form.base_fields['venue'] = this_venue.name
question_form.base_fields['survey'] = this_survey.name
return render_to_response("survey/questions.html", locals(), context_instance=RequestContext(request))

but im not sure what to dowith it in the template and this is the bit that isn't really covered in the tutorials.

i've worked out that the following works

    {% for base_field in question_form.base_fields %}
        {{ base_field.type }}
    {% endfor %}

but i thought the point of building it as a form was to be able to do something 开发者_如何学编程like

question_form.as_p 

and wrap it in my own form tags.

have i missed the point or should as_p work (it doesn't).

You haven't instantiated the form in your view. make_question_form returns a new form class - normally when you use a form class in your view you do form = MyFormClass() or form = MyFormClass(request.POST).

So you need to do form = question_form() before the render_to_response, then you'll be able to do {{ form.as_p }} in the template.
