Ticket #706 (defect)

When Routes is unable to find a route, it will throw: AttributeError?: MainController? instance has no attribute 'foo'

Example based on the cherrypy docs:

# -*- encoding: UTF-8 -*-
import os

import cherrypy

class MainController:

    def index(self):
        return "This is the main page"

class BlogController:

    def index(self, entry_id):
        return "This is blog entry no. %d" % int(entry_id)

    def edit(self, entry_id):
        return "This is an edit form for blog entry no. %d" % int(entry_id)


dispatcher = None

def setup_routes():
    d = cherrypy.dispatch.RoutesDispatcher()
    d.connect('blog', 'myblog/:entry_id/:action', controller=BlogController())
    d.connect('main', ':action', controller=MainController())
    dispatcher = d
    return dispatcher

conf = {
    '/': {
        'request.dispatch': setup_routes()
    }
}

cherrypy.config.update(conf)
cherrypy.quickstart(None, config=conf)

Sending /foo produces a 500 AttributeError?.

The problem is on line 323 of _cpdispatch.py: handler = getattr(controller, action)

This should become: handler = getattr(controller, action, None)

This will cause a default value of None instead an exception, and this None will result in a 404.
