Title:
Security Code:
Body:
(use
this
wiki markup)
Controller functions can return: - a string: ``return "Hello"`` and this would be the body of the returned page - a dictionary ``return dict(message="Hello")`` and this would be passed to a view - streaming data ``return response.stream(open('filename','rb'))`` to return a large file - a set of xmlrpc exposed methods `return response.xmlrpc(request,methods)`` Often you just return a dictionary containing a definition of those variables you want to pass to the view. By default a function() in controller.py will be rendered by a view called controller/function.html. If this view is not found the generic.html view renders the variables in the dictionary. A controller function can also return a string. In this case the view is not executed and the string is returned instead.
