Adding extra data to Django Rest Framework results for entire result set

Question

I\'m using Django Rest Framework and need to add extra data to a result set. Specifically, where you would usually have:

{
    \"count\": 45, 
    \"next\":          


        

Answer 1

Use SerializerMethodField as mentioned in this solution.

It can be used to add any sort of data to the serialized representation of your object. (REST framework doc)

Example from the documentation:

from django.contrib.auth.models import User
from django.utils.timezone import now
from rest_framework import serializers

class UserSerializer(serializers.ModelSerializer):
    days_since_joined = serializers.SerializerMethodField()

    class Meta:
        model = User

    def get_days_since_joined(self, obj):
        return (now() - obj.date_joined).days
