Hi Daniel, thanks for looking at this!
Here is my views.py code related to this:
@login_required
def wine_add_page(request):
if request.method == 'POST':
form = WineAddForm(request.POST)
if form.is_valid():
#create or get dummy wine
wine, dummy = Wine.objects.get_or_create(
wine_name=form.cleaned_data['wine_name']
)
#update wine_name
winerater.wine_name = form.cleaned_data['title']
#if the bookmark is being updated, clear old tag list
if not created:
winerater.tag_set.clear()
#create new tage list
tag_names = form.cleaned_data['tags'].split()
for tag_name in tag_names:
tag, dummy = Tag.objects.get_or_create(name=tag_name)
wnerater.tag_set.add(tag)
#save wine to DB
winerater.save()
return HttpResponseRedirect(
'/user/%s/' % request.user.username
)
else:
form = WineAddForm()
variables = RequestContext(request, {
'form': form
})
return render_to_response('wine_add.html', variables)
