The only thing you need to do that you're not doing is to actually
pass the instance of Question (or Choice) to the form when you
instantiate it.
Assuming that 'question' is the PK of the Question object:
def contact(request, question):
question_obj = Question.objects.get(pk=question)
if request.method == 'POST':
form = Questionform(request.POST, instance=question_obj)
if form.is_valid():
form.save()
return HttpResponseRedirect('/submission/')
else:
form = Questionform(instance=question_obj)
return render_to_response('contact.html', {
'form': form
})
Note that HttpResponseRedirect takes a *URL*, not a template/context.
It tells the user's browser to request a different URL so that they
can't submit the form twice.

Accessing Model field from ModelForm?
I have a basic form that shows what a person entered when it is
submitted. However, it shows up as a form.CharField (textbox) instead
of model.CharField. Is there a way to access the model's saved data
from the Forms? Also does form_for_model (http://www.djangobook.com/en/
1.0/chapter07/) no longer exist? I can't get it to load.
models.py:
from django.db import models
from django.forms import ModelForm
class Question(models.Model):
question = models.CharField('Question', max_length = '200',
primary_key = True)
pub_date = models.DateField(auto_now_add = True)
def __unicode__(self):
return self.question
class Choice(models.Model):
Question = models.ForeignKey(Question)
choice = models.CharField(max_length = '200')
class Questionform(ModelForm):
class Meta:
model = Question
class Choiceform(ModelForm):
class Meta:
model = Choice
view:
from qotd.models import *
from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
def contact(request, question):
if request.method == 'POST': # If the form has been submitted...
form = Questionform(request.POST) # A form bound to the POST
data
if form.is_valid():
form.save()
#return HttpResponseRedirect('results.html', {'form': form}
else:
form = Questionform()
return render_to_response('contact.html', {
'form': form
})
template:
{% if not form.is_valid %}
{{ form.as_p }}
{% endif %}
{% if form.is_valid %}
{{ form.question }}
{% endif %}
