A quick example explaining multiple nested serializers in Django Rest Framework.

serializers.py

from rest_framework import serializers
from myapp import models


class ProfileSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Profile


class UserSerializer(serializers.ModelSerializer):
    profile = ProfileSerializer()
    
    class Meta:
        model = models.User


class CommentSerializer(serializers.ModelSerializer):
    user = UserSerializer()

    class Meta:
        model = models.Comment
