How do I make a trailing slash optional with webapp2?

Question

I\'m using the new webapp2 (now the default webapp in 1.6), and I haven\'t been able to figure out how to make the trailing slash optional in code like this:

web         


        

Answer 1

I don't like the RedirectRoute class because it causes an unnecessary HTTP Redirect.
Based on the documentation for webapp2 Route class, here is a more detailed answer in this webapp2.Route with optional leading part thread.

Short Answer

My route patterns works for the following URLs.

1. /
2. /feed
3. /feed/
4. /feed/create
5. /feed/create/
6. /feed/edit/{entity_id}

SITE_URLS = [
    webapp2.Route(r'/', handler=HomePageHandler, name='route-home'),

    webapp2.Route(r'/feed/<:(create/?)|edit/>',
        handler=MyFeedHandler,
        name='route-entity-create-or-edit'),

    webapp2.SimpleRoute(r'/feed/?',
        handler=MyFeedListHandler,
        name='route-entity-list'),
]

Hope it helps :-)
