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 ...
