Taking advantage of model serializers
In Chapter 1, Installing the Required Software and Tools, we created the toy model (the Toy
class) and its serializer (the ToySerializer
class). When we wrote the code for the ToySerializer
class, we had to declare many attributes with the same names that we used in the Toy
class. The ToySerializer
class is a subclass of the rest_framework.serializers.Serializer
superclass; it declares attributes that we manually mapped to the appropriate types, and overrides the create
and update
methods. However, we repeated a lot of code and information that was already included in the toy model, such as the types and the max_length
values that specify the maximum length for each string field.
Now, we will take advantage of model serializers to simplify code and to avoid repeating information that is already included in the model. We will create a new version of the existing ToySerializer
class that will inherit from the rest_framework.serializers.ModelSerializer
superclass...
