Tim,
I added your code into my view. However, it seems to error out on me
when I get to the line 'if 'color' in request and request['color'] <>
NO_COLOR: '. The error says:
KeyError at /rugs/searchresult/
'0 not found in either POST or GET'
//////////////
Here is my view
def searchresult(request):
if request.method == 'POST':
myprice = {}
mysize = {}
if request['price'] == "---------------":
f = Price.objects.all()
else:
myprice['price_cat'] = request['price']
f = Price.objects.filter(**myprice)
if request['size'] == "---------------":
e = Size.objects.all()
else:
mysize['size_cat'] = request['size']
e = Size.objects.filter(**mysize)
dict = {}
for a in f:
for b in e:
g = Choice.objects.filter(price=a, size=b)
for h in g:
NO_COLOR = "---------------"
styles =
Choice.objects.get(id=h.id).style_set
if 'color' in request and
request['color'] <> NO_COLOR:
styles =
styles.filter(color_cat=request['color'])
for j in styles:
dict[j] = j
return render_to_response('searchresult.html', {'s': dict})
/////////////////
Also, when I do a 'assert False, styles' after the line 'styles =
Choice.objects.get(id=h.id).style_set'
I get the following error:
'<django.db.models.fields.related.ManyRelatedManager object at
0x016EAA90>
Don't I want styles to bring back a style?
///////////////
Thanks for you help
