@auth.requires_login() is a Python decorator, so you have to put it on the
line immediately before the function you want to decorate -- in this case:
@auth.requires_login()
def data_as_json():
stuff = get_data()
return json(stuff)
See http://web2py.com/book/default/chapter/08#Decorators for more details.
Also, any function in your controller file that takes no arguments or
doesn't start with two underscores can be accessed via a URL request, so you
may not want a function like get_data() in your controller. If the sole
purpose of that function is to be called by other functions (such as
data_as_json), then you should either start it with two underscores (i.e.,
def __get_data()), make sure it takes at least one argument (e.g., def
get_data(dummy_arg)), or import it from a module. For more details, see
http://web2py.com/book/default/chapter/04#Dispatching.
