Prompt Detail:

Sure, here is an example of how you can create a Django API for a todo React website with user authentication and CRUD (create, read, update, delete) functionality:

  1. Install Django Rest Framework:

You can install Django Rest Framework using pip:

pip install djangorestframework
  1. Create a new Django app:
python manage.py startapp todo_api
  1. Add the app to the INSTALLED_APPS in settings.py:
css
INSTALLED_APPS = [ ... 'rest_framework', 'todo_api',]
  1. Create a User model:
python
from django.contrib.auth.models import AbstractUser class User(AbstractUser): pass
  1. Create a serializer for the User model:
python
from rest_framework import serializers from .models import User class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ['id', 'username', 'email', 'password'] extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): user = User.objects.create_user(**validated_data) return user
  1. Create views for registering new users, logging in, creating, reading, updating and deleting todos:
python
from django.shortcuts import get_object_or_404 from rest_framework import generics, permissions, status from rest_framework.response import Response from rest_framework_simplejwt.views import TokenObtainPairView from .models import User, Todo from .serializers import UserSerializer, TodoSerializer class RegisterView(generics.CreateAPIView): queryset = User.objects.all() permission_classes = [permissions.AllowAny] serializer_class = UserSerializer class LoginView(TokenObtainPairView): pass class TodoListView(generics.ListCreateAPIView): queryset = Todo.objects.all() serializer_class = TodoSerializer permission_classes = [permissions.IsAuthenticated] def perform_create(self, serializer): serializer.save(user=self.request.user) class TodoDetailView(generics.RetrieveUpdateDestroyAPIView): queryset = Todo.objects.all() serializer_class = TodoSerializer permission_classes = [permissions.IsAuthenticated] def get_object(self): obj = get_object_or_404(Todo, id=self.kwargs['pk'], user=self.request.user) return obj
  1. Add URLs for the views:
python
from django.urls import path from rest_framework_simplejwt.views import TokenRefreshView from .views import RegisterView, LoginView, TodoListView, TodoDetailView urlpatterns = [ path('register/', RegisterView.as_view(), name='register'), path('login/', LoginView.as_view(), name='login'), path('refresh/', TokenRefreshView.as_view(), name='refresh'), path('todos/', TodoListView.as_view(), name='todo-list'), path('todos/<int:pk>/', TodoDetailView.as_view(), name='todo-detail'), ]

This code creates four endpoints:

  • /register/ - for registering new users
  • /login/ - for logging in
  • /todos/ - for creating and reading todos
  • /todos/int:pk/ - for updating and deleting todos

Note that this is just an example and you may need to modify it to fit your specific needs. You should also add appropriate error handling and authentication mechanisms to ensure the security and robustness of your API.
