Rajeesh,
Following your advice, Im think I've about solved the problem.
I've got one last exception, I hope.
Here is the new iteration of views.py, all other files remain the same.
In short the page renders to the screen, the problem arises when values are
submitted
to the view.
I get an exception "can't multiply sequence by non-int of type 'tuple".
I've created a new
function that describes the multiplication operation, that is used within
the render function, this
is where the error occcrs. I'm not referencing the variables properly, I
guess.
def calculation(request):
"""function that computes submission"""
if request.method == 'POST':
form = FinanceTable(request.POST)
if form.is_valid():
cd =form.cleaned_data
capital = cd['capital'],
tax_rate = cd['tax_rate'],
useage = projfin(request, capital, tax_rate)
response_dict = {'capital' : capital, 'tax_rate' : tax_rate,
'useage' : useage}
return render_to_response('textplusnumbers.html' , response_dict)
else:
form = FinanceTable(
initial={'capital' : 1000, 'tax_rate' : .07}
)
return render_to_response('textplusnumbers.html' , {'form' : form})
def projfin(request, capital, tax_rate):
useage = capital * tax_rate
return useage
