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

Here's how I handle these routes.

from webapp2 import Route
from webapp2_extras.routes import PathPrefixRoute
import handlers

urls = [
  Route('/foo<:/?>', handlers.Foo),
  Route('/bars', handlers.BarList),
  PathPrefixRoute('/bar', [
    Route('/', handlers.BarList),
    Route('/<:/?>', handlers.Bar),
  ]),
]
...

It's important to note that your handlers will need to define *args and **kwargs to deal with the potential trailing slash, which gets sent to them as an argument using this method.

class Bar(webapp2.RequestHandler):

  def get(bar_id, *args, **kwargs):
    # Lookup and render this Bar using bar_id.
    ...
