Hi James,
It sounds like you might be thinking of how a PHP app might work, where your
URL points to a particular .php file, and that file is then processed to
generate the returned web page. web2py does not work that way. To get a
better understanding of how web2py does it, I recommend looking at
http://web2py.com/book/default/chapter/03 and
http://web2py.com/book/default/chapter/04#Dispatching. If you're coming from
PHP, you might also look at http://www.web2py.com/AlterEgo/default/show/106.
In web2py, you don't call (or redirect to) views directly. Instead, all
requests are handled by controllers (and the functions within the
controllers). A URL of the form '/app/c/f' calls the function 'f()' in the
controller 'c.py' in the application 'app'. If f() returns a string, then no
view is called, and the string is simply returned as the response. If f()
returns a Python dictionary, then web2py looks for a view file with the same
name as the function (if the controller is 'c.py', web2py expects to find
the view file in a folder named 'c' inside the 'views' folder). If the URL
does not include an extension for 'f', then web2py assumes an .html
extension for the view file.
Taking your example, if you want someone to go to
'different_controller/protected_page', inside your 'controllers' folder, you
need a 'different_controller.py' file that includes a 'protected_page()'
function. Assuming it's an HTML page, there should also be a
'different_controller' folder inside your 'views' folder, and that folder
should include a 'protected_page.html' view file to render the output of the
'protected_page()' function.
Note, if you want to redirect someone to a particular page, you cannot
simply set response.view to a different value -- that will just tell the
current function to render it's output using a different view -- it will not
call the function associated with the different view. To redirect, use the
'redirect' command (
http://web2py.com/book/default/chapter/04#HTTP-and-redirect), and specify
the page using the URL() function (
http://web2py.com/book/default/chapter/04#URL).
Hope that helps.
Anthony
