Creating resource classes to handle users

We just want to be able to create users and use them to authenticate requests. Thus, we will just focus on creating resource classes with just a few methods. We won't create a complete user management system.

We will create the resource classes that represent the user and the collection of users. First, we will create a UserResource class that we will use to represent a user resource. Open the api/views.py file and add the following lines after the line that creates the Api instance. The code file for the sample is included in the restful_python_chapter_07_02 folder:

class UserResource(AuthRequiredResource): 
    def get(self, id): 
        user = User.query.get_or_404(id) 
        result = user_schema.dump(user).data 
        return result 

The UserResource class is a subclass of the previously coded AuthRequiredResource and declares a get methods that will be called when the HTTP method with the same name arrives as a request on the represented resource...
