Dispatch and Generate URL

dispatch with url patterns.

example helo application:

>>> from webob.dec import wsgify
>>> @wsgify
... def greeting(request):
...     return "Hello, %s" % request.urlvars['name']

create and configure URL Dispatcher:

>>> from webdispatch import URLDispatcher
>>> dispatcher = URLDispatcher()
>>> dispatcher.add_url('top', '/hello/{name}', greeting)

invoke dispatcher as WSGI Application:

>>> from webob import Request
>>> req = Request.blank('/hello/webdispatch')
>>> res = req.get_response(dispatcher)
>>> res.body
'Hello, webdispatch'

Action Dispatch

ActionDispatcher invokes object method with action name from urlvars.

action handler class:

>>> class MyHandler(object):
...     @wsgify
...     def greeting(self, request):
...         return "Hello"

create and configure ActionDispatcher:

>>> from webdispatch import ActionDispatcher
>>> actiondispatcher = ActionDispatcher()
>>> actiondispatcher.register_actionhandler(MyHandler)

add action url with urlvars named action:

>>> dispatcher.add_url('action_dispatch', '/actions/{action}', actiondispatcher)

invoke wsgi appclication.:

>>> req = Request.blank('/actions/greeting')
>>> res = req.get_response(dispatcher)
>>> res.body
'Hello'

Method Dispatch

dispatch by HTTP METHOD restfully.

sample wsgi app:

>>> @wsgify
... def get_hello(request):
...    return "Get Hello"
>>> @wsgify
... def post_hello(request):
...    return "Post Hello"

create and configure:

>>> from webdispatch import MethodDispatcher
>>> restapp = MethodDispatcher()
>>> restapp.register_app('get', get_hello)
>>> restapp.register_app('post', post_hello)

Each applications are registered with HTTP Method name.

invoke WSGI application:

>>> req = Request.blank('/')
>>> res = req.get_response(restapp)
>>> res.body
'Get Hello'
