I think this is a newbie question, but I can't find the answer in the docs
or Group posts.
If I have a value stored in my data tables like:
a = Some_table.objects.filter(pk=10).values('number')
b = Another_table.objects.filter(pk=2).values('another_number')
and maybe even a value from a form
c = form...
c.third_number
So, in my view.py, I'd like to be able to do something like
def....():
a = Some_table.objects.filter(pk=10).values('number')
b = Another_table.objects.filter(pk=2).values('another_number')
c = form...c.third_number
x = b - (a*c)
return render(request, 'results.html', {'x':x})
I know, in a view.py, I can do something like a=123, b=456, c=789,
x=b-(a*c) , render x....but as soon as those values come from the queryset
I can't do math on them. Is it because they are returned as u'value'? So
do I need to cast them as numbers? I think when I tried that the error
said I couldn't cast the queryset value as an int or float or..
Trying to following mvt(mvc) conventions and keep that stuff out of the
template/html/javascript
I'm sure I'm either missing something simple or doing something dumb. Any
help?
