How Can I Add Field In Serializer?

Below is my serializer.py file: from rest_framework import serializers class TaskListSerializer(serializers.Serializer): id = serializers.CharField() user_id = serializer

Solution 1:

Use serializers.SerializerMethodField()

class TaskListSerializer(serializers.ModelSerializer):
complex_things = serializers.SerializerMethodField()

    def get_complex_things(self, obj):
        result_of_complex_things = 2 + 2
        return result_of_complex_things
