Thanks to justinf on #django for pointing out that I need to pass in
request.FILES in my formset. If you're working with file fields (and
image fields), the parameter is essential. Below is my current
working view for future references.
-------------------------------------------------------------------------------------------------------------------
def add_post(request):
section_id = int(request.GET.get('s', 0))
category_id = int(request.GET.get('c', 0))
PostImageFormSet = \
inlineformset_factory(Post, PostImage, form=PostImageForm,
max_num=4, extra=4)
if request.method == 'POST':
form = PostForm(request.POST)
formset = PostImageFormSet(request.POST, request.FILES)
if form.is_valid() and formset.is_valid():
new_post = form.save(commit=False)
new_post.poster = request.user
new_post.save()
formset.instance = new_post
formset.save()
return HttpResponseRedirect(new_post.get_absolute_url())
else:
form = PostForm()
formset = PostImageFormSet()
return render_to_response('classified/post_form.html',
{ 'form': form,
'formset': formset,
'add': True,
'section_id': section_id,
'category_id': category_id,
'categories': Category.objects.all(),
'filtered_section':
filtered_section },
context_instance=RequestContext(request))
