If you just want to avoid duplicating code to create the "income" variable,
you could simply extract that into a separate function and call it from
within each of the two controller actions. If you really want to have a
single controller action for both the initial full page load and for
subsequent Ajax updates, you can do something like this:
def overview():
income = [some code]
if request.ajax:
return response.json(income)
[more code]
return dict(income=json(income), form=form, bank=bank)
