Re: 'Toolbox' object has no attribute 'CORS'

Hey, try this: This is a server I wrote in CherryPy it should accept CORS 
requests. It's been working for me

===

import cherrypy

from sys import path
from os import getcwd 


# assumes there's a controller's module and a file name UsersController.py

from controllers.UsersController import Users

def CORS():
    """Allow AngularJS apps not on the same server to use our API
    """
    cherrypy.response.headers["Access-Control-Allow-Origin"] = "*" 
    cherrypy.response.headers["Access-Control-Allow-Headers"] = \
    "content-type, Authorization, X-Requested-With"
    cherrypy.response.headers["Access-Control-Allow-Methods"] = 'GET, POST'

if __name__ == '__main__':
    """Starts a cherryPy server and listens for requests
    """

    userController  = Users()
    
    cherrypy.tools.CORS = cherrypy.Tool('before_handler', CORS)

    cherrypy.config.update({
        'server.socket_host': '0.0.0.0',
        'server.socket_port': 8080,
        'tools.CORS.on': True,
    })

    # API method dispatcher
    # we are defining this here because we want to map the HTTP verb to
    # the same method on the controller class. This _api_user_conf will
    # be used on each route we want to be RESTful
    _api_conf = {
        '/': {
            'request.dispatch': cherrypy.dispatch.MethodDispatcher(),
        }
    }

 

    cherrypy.tree.mount(userController, '/api/users', _api_conf)
    
    cherrypy.engine.start()
    cherrypy.engine.block()
