3. Traversal / URL dispatch
config.add_route(‘route1’, ‘{var1}/{var2}’)
config.add_view(‘module.views.view1’, route_name=‘route1’)
/foo/bar
Object based traversal with a route object
config.add_view(‘module.views.view1’, route_name=‘route1’)
/a/b/c/route1
class Resource(object):
def __init__(self, subobjects):
self.subobjects = subobjects

config.add_route('home', '{foo}/{bar}/*traverse',
factory=‘mypackage.routes.root_factory')
