ModelForm not passing all parameters - django-views

Question

After some great help by #kreigar I was able to start using django's ModelForm instead of form.Forms. Only problem now is that I am not passing the two primary keys to associate my review form :-(.
Currently my view looks like such:
#views.py
#login_required
def wine_review_page(request, wine_id):
wine = get_object_or_404(Wine, pk=wine_id)
review = None
if Review.objects.filter(user=request.user, wine=wine).exists():
review = Review.objects.get(user=request.user, wine=wine)
if request.method == 'POST':
form = WineReviewForm(request.POST, instance=review)
if form.is_valid():
form.save()
return HttpResponseRedirect('/detail/%s/' % wine_id )
else:
form = WineReviewForm(instance=review)
variables = RequestContext(request, {'form': form, 'wine': wine })
return render_to_response('wine_review_page.html', variables)`
and my model form like this:
#models.py
class WineReviewForm(ModelForm):
class Meta:
model = Review
widgets = {
'wine': HiddenInput(),
'user': HiddenInput(),
'like_dislike': HiddenInput(),
'fave': HiddenInput(),
'sweet_dry': HiddenInput(),
'crisp_buttery: HiddenInput(),
'fruity_earthy': HiddenInput(),
'smooth_spicy': HiddenInput(),
'light_robust': HiddenInput(),
'label_rating': HiddenInput()
}
Wine_review_form:
<form method="post" action="/review/{{ wine.id }}/">
{% csrf_token %}
{{form.as_p}}
<div id="form_div" data-role="fieldcontain">
<script>
$('#form_div > input').hide();

When checking my post request the only things I am not passing are the: wine_id and the user_id. This is really confusing.
Am I missing soomething simple?
I looked through documentation and examples but no luck so far.

Answer 1

It actually looks like you wouldn't need your wine_id and user_id (unless you want to allow users to post reviews for other users, or switch wines they are reviewing on the fly).
This should work for you:
#login_required
def wine_review_page(request, wine_id):
wine = get_object_or_404(Wine, pk=wine_id)
if Review.objects.filter(user=request.user, wine=wine).exists():
review = Review.objects.get(user=request.user, wine=wine)
else:
review = Review(user=request.user, wine=wine) #this added
if request.method == 'POST':
form = WineReviewForm(request.POST, instance=review)
if form.is_valid():
form.save()
return HttpResponseRedirect('/detail/%s/' % wine_id )
else:
form = WineReviewForm(instance=review)
variables = RequestContext(request, {'form': form, 'wine': wine })
return render_to_response('wine_review_page.html', variables)
If you do want to allow the user to modify either of those fields, edit your question to show your template or how the users are submitting data, since all your fields are using hiddenInput widgets, Its hard to tell how any data would get into the request.POST
