Mastering DRF Serializers

We have learned all the important concepts of DRF serializers, so in this section, we shall learn how we can use DRF serializers efficiently, as well as a few new concepts that can help us master them even further.

Using source

We learned earlier how we can use the source option to perform multiple types of operations, and moving forward, you should use this argument in the serializer field whenever possible. This is because it drastically reduces the need to write manual code for basic tasks such as renaming fields, making a flat response structure, or accessing data from related fields.

Embracing SerializerMethodField

SerializerMethodField gives us a lot of flexibility to perform data manipulation on the fly. We should use method serializers whenever we need to perform computation involving multiple fields of a single object, or to transform data.

Using validators

Always try to add validators so that we don’t need to use custom code...
