Creating the model

Now, we will create a simple SurfboardMetricModel class that we will use to represent metrics. Remember that we won't be persisting the model in any database or file, and therefore, in this case, our class will just provide the required attributes and no mapping information.

Create a new models subfolder within the metrics/metrics folder. Then, create a new metrics.py file in the metrics/metrics/models subfolder. The following lines show the code that declares the necessary imports that we will require for many classes. This will then create a SurfboardMetricModel class in this file. The code file for the sample is included in the restful_python_2_09_01 folder, in the Pyramid01/metrics/metrics/models/metrics.py file:

from enum import Enum 
from marshmallow import Schema, fields 
from marshmallow_enum import EnumField 
 
 
class SurfboardMetricModel:
