Hopefully my last question on this,
How do I get back to the page with the form, perhaps with a "Thank
You" message, without having the POST still available if you hit
refresh.
I figured I'd use 'reverse' but not quite sure why it isn't
working ...
Here's where I am now:
#views.py
def record_detail(request, slug):
record = Record.objects.get(slug=slug)
if request.method == 'POST':
form = RatingForm(request.POST)
if form.is_valid():
record_rating = Rating()
record_rating.item_id = record.id
record_rating.writer_id = request.user.id
record_rating.rating = form.cleaned_data['rating']
record_rating.save()
return render_to_response(reverse('record_detail',
args=[slug]))
else:
form = RatingForm()
return render_to_response('records/detail.html', {'record_detail':
record, 'form': form}, context_instance=RequestContext(request))
I get the below error.
NoReverseMatch at /records/temp-record-name/
Reverse for 'record_detail' with arguments '(u'temp-record-name',)'
and keyword arguments '{}' not found.
And even if it does get passed back to the original page, how would I
have a "Thank You" message?
Thanks again,
d
