Idea of multiple objects embedded in one class to use a particular handler depending on the Accept header.

cp_multihandler.py

import cherrypy

class MultiViewHandler(object):
    def __new__(cls):
      """Do something to be able to use the right view to the
      right Accept header
      """

class SpecialDispatcher(cherrypy.dispatcher.Dispatcher)
    """Custom dispatcher to use the special properties of the
    `MultiViewHandler` childs.
    """

class JSONPost(object):

    @cherrypy.expose
    def index(self):
        pass

    @cherrypy.expose
    def default(self, id):
        pass

class HTMLPost(object):

    @cherrypy.expose
    def index(self):
        pass

    @cherrypy.expose
    def default(self, id):
        pass

class Post(MultiViewHandler):
    __views = [('text/html', HTMLPost),
               ('application/json', JSONPost)]
  

cherrypy.quickstart(Post(), config={'/': {'request.dispatcher': SpecialDispatcher()}})

Another way to do something similar is with metaclasses.
