Hello people, my ongoing adventures in firstdjangoappland continue thus:
I'm putting together a simple search app for a car project. On entry,
user sees a list of 5 random cars. He can use up to two comboboxes to
filter the results (car model and fuel type).
This is what I've come up with on my home() view, so far, and it looks
really ugly.
def home(request):
results = {}
# these 2 guys are the filters
model_list = Model.objects.all()
gorivo_list = Gorivo.objects.all().order_by('opis')
selected_model_id = 0
selected_gorivo_id = 0
if request.POST:
# this handles 'SELECTED' attribute on comboboxes
try:
selected_model_id = int(request.POST['model_id'])
except:
pass
try:
selected_gorivo_id = int(request.POST['gorivo_id'])
except:
pass
# and this should take care of the filtering... but I'm stumped
really
# both filters should add up
results = Vozilo.objects.all()
if selected_model_id != 0:
results =
results.filter(model_id__exact=selected_model_id)
if selected_gorivo_id != 0:
results =
results.filter(gorivo_id__exact=selected_gorivo_id)
else:
# no POST, we show 5 random cars.
results = Vozilo.objects.order_by('?')[:5]
return render_to_response('cars/home.html', {
'model_list':model_list,
'gorivo_list':gorivo_list,
'selected_model_id':selected_model_id,
'selected_gorivo_id':selected_gorivo_id,
'results': results
})
There must be a better way of doing this, right? I'm a terrible newbie
both at Python and Django --and I'm not a kid anymore, so no more time
to spare hitting my head on walls :-)
Insights? Ideas?
Thanks a million,
