[web2py] Re: Controller to Ajax Function AND View

[Anthony]

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)
