Building RESTful Python Web Services

Configuring output fields

Now, we will create a message_fields dictionary that we will use to control the data that we want Flask-RESTful to render in our response, when we return MessageModel instances. Open the previously created api/api.py file and add the following lines. The code file for the sample is included in the restful_python_chapter_05_01 folder.

message_fields = { 
    'id': fields.Integer, 
    'uri': fields.Url('message_endpoint'), 
    'message': fields.String, 
    'duration': fields.Integer, 
    'creation_date': fields.DateTime, 
    'message_category': fields.String, 
    'printed_times': fields.Integer, 
    'printed_once': fields.Boolean 
} 
 
 
message_manager = MessageManager() 

We declared the message_fields dictionary (dict) with key-value pairs of strings and classes ...
