Basic Serializers

Imagine you have a Django model for Book and you want to serialize this data to be returned as JSON through an API endpoint.

Models

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)
    published_year = models.IntegerField()

Serializers

from rest_framework import serializers
from .models import Book

class BookSerializer(serializers.Serializer):
    title = serializers.CharField(max_length=100)
    author = serializers.CharField(max_length=100)
    published_year = serializers.IntegerField()

Views

from rest_framework.views import APIView
from rest_framework.response import Response
from .models import Book
from .serializers import BookSerializer

class BookListView(APIView):
    def get(self, request):
        books = Book.objects.all()
        serializer = BookSerializer(books, many=True)
        return Response(serializer.data)

URLs

from django.urls import path
from .views import BookListView

urlpatterns = [
    path('books/', BookListView.as_view(), name='book-list'),
]

Summary

• Basic Serializers: Used to serialize non-model-based data or when you need complete control over how each field is serialized.
