Nathan,
Thanks for the iteritems() method. I implemented that into my code.
However, 'if values != 0:' never evaluates to False. Even though some
of the forms elements values are 0. For example when I do a assert
False, values on one of those elements I see:
AssertionError at /rugs/cart/addpad/
[u'0']
Does that mean that the value is 0? below is my view function and
template code:
//////////////
def addpad(request):
if request.method == 'POST':
pads = request.session.get('pad', [])
for a, values in request.POST.iteritems():
#assert False, values
if values != 0:
opad = RugPad.objects.get(id=a)
s = opad.size
p = opad.price
pads.append({'size': s, 'price': p})
request.session['pad'] = pads
else:
assert False, "It got here" #It never gets here
return render_to_response('addpad.html', {'spad':
request.session['pad']})
/////////////
{% for a in pad %}
<tr>
<td>
<select name="{{ a.id }}">
<option value="0">---</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select> {{ a.size }} -- ${{ a.price }}
</td>
</tr>
{% endfor %}
/////////////////////////
I'm thinking that my values variable is not a int. I tried
int(values) but that still didn't work. How do I get it so that
values is a int so that I can do 'if values != 0:'?
Thanks
