Views in Django

 Views in Django

DRF includes a set of generic views that can be used to build CRUD (Create, Retrieve, Update, Delete) APIs for Django models. Here's an example view for a Book model:

python

from rest_framework import generics

from .models import Book

from .serializers import BookSerializer

class BookList(generics.ListCreateAPIView):

    queryset = Book.objects.all()

    serializer_class = BookSerializer

class BookDetail(generics.RetrieveUpdateDestroyAPIView):

    queryset = Book.objects.all()

    serializer_class = BookSerializer

In this example, we define two views: BookList and BookDetail. BookList is a view that lists all books and allows creating new ones. BookDetail is a view that retrieves, updates, or deletes a single book.

We specify the queryset (i.e., the set of objects to be used) and serializer for each view.

We can add these views to our app's urls.py file:

python

from django.urls import path

from .views import BookList, BookDetail

urlpatterns = [

    path('books/', BookList.as_view(), name='book-list'),

    path('books/<int:pk>/', BookDetail.as_view(), name='book-detail'),

]

This sets up two URL patterns: /books/ for the BookList view and /books/<id>/ for the BookDetail view.
