pecan.routing – Pecan Routing¶
pecan.routing module is the basis for all object-dispatch
routing in Pecan.
lookup_controller(obj, remainder, request=None)¶
Traverses the requested url path and returns the appropriate controller object, including default routes.
Handles common errors gracefully.
find_object(obj, remainder, notfound_handlers, request)¶
‘Walks’ the url path in search of an action for which a controller is implemented and returns that controller object along with what’s left of the remainder.
This function is used to define an explicit route for a path segment.
You generally only want to use this in situations where your desired path segment is not a valid Python variable/function name.
For example, if you wanted to be able to route to:
...the following is invalid Python syntax:
class Controller(object): with-dashes = SubController()
...so you would instead define the route explicitly:
class Controller(object): pass pecan.route(Controller, 'with-dashes', SubController())
