The design goal of Flask-RESTful is to provide resources built on top of Flask pluggable views. The pluggable views provide a simple way (defining a resource method) to access the HTTP methods. Consider the following example code:

   class Todo(Resource): 
    def get(self, user_id): 
        .... 
    def delete(self, user_id): 
        .... 
    def put(self, user_id): 
        args = parser.parse_args() 
        ....
