title: Django form object has no attribute issue
body: <p>I have a simple form and am trying to POST it to a simple service.</p>
  
  <p>The form model:</p>
  
  <pre><code>class order_form(forms.Form):
      name = forms.CharField(max_length=100)
      phone = forms.CharField(max_length=20)
      email = forms.CharField(max_length=100)
      address = forms.CharField(max_length=200)
      ordered_picture = forms.CharField()
  </code></pre>
  
  <p>the view (haven't sorted all the cleared_data bits and stuff yet):</p>
  
  <pre><code>def place_order(request):
      result = dict()
      if request.method == 'POST':
          try:
              form = order_form(request.POST)
              if not picture.objects.filter(id=form.ordered_picture).exists():
                  result['status'] = 'error'
                  result['message'] = 'Ordered picture does not exist'
              new_order = order()
              new_order.name = form.data.name
              new_order.phone = form.data.phone
              new_order.email = form.data.email
              new_order.address = form.data.address
              new_order.ordered_picture = int(form.data.ordered_picture)
              new_order.save()
              result['status'] = 'ok'
              result['message'] = new_order.id
          except Exception, e:
              result['status'] = 'error'
              result['message'] = e.message
      else:
          result['status'] = 'error'
          result['message'] = 'Only HTTP POST Method is supported by this service'
      return HttpResponse(content=simplejson.dumps(result))
  </code></pre>
  
  <p>Here is a copy of POST data that goes in:</p>
  
  <pre><code>csrfmiddlewaretoken:77d1ba277ef43838e670f598c2a128b6
  name:qwe
  phone:qwe
  email:qwe
  address:qwe
  ordered_picture:1
  </code></pre>
  
  <p>and I get the following:</p>
  
  <pre><code>{"status": "error", "message": "'order_form' object has no attribute 'ordered_picture'"}
  </code></pre>
  
  <p>this "object has no attribute" thing is popping out at Exception right after form = order_form(request.POST) is attempted. I am about to break my head - why is this telling me the form does not have this attribute when it does in reality? </p>
