Installing and setting up DRF

In this video, you'll learn how to install and configure DRF in a Django project with ease. You'll have the option to use pip or pipenv to manage the dependencies.

Installing DRF

1. Start by opening the terminal and navigating to your project directory.
2. If using pipenv, run the following commands:

pipenv install django
pipenv shell
pipenv install djangorestframework

1. If using pip, run the following command:

pip or pip3 install djangorestframework

Creating a Django project

In the terminal, run the following commands:

django-admin startproject BookList .
python manage.py startapp BookListAPI

Configuring DRF

1. Open the settings.py file in the project directory and find the INSTALLED_APPS section.
2. Add rest_framework and BookListAPI to the end of the list.

Creating an API Endpoint

1. In the views.py file of the BookListAPI app, add the following code:

from django.shortcuts import render
from rest_framework.response import Response
from rest_framework import status
from rest_framework.decorators import api_view

# Create your views here.
@api_view()
def books(request):
    return Response("list of books", status=status.HTTP_200_OK)

1. Create a new file called urls.py in the BookListAPI directory and add the following code:

from django.urls import path
from . import views

urlpatterns = [
    path("books/", views.books),
]

1. In the project's main urls.py file, add the following line to link the newly created books endpoint:

from django.urls import include

urlpatterns = [
    path('api/', include('BookListAPI.urls')),
]

Testing the API Endpoint

1. Run the migrate command in the terminal:

python3 manage.py migrate

1. Start the web server using the following command:

python3 manage.py runserver

1. Access the books endpoint by making an HTTP GET request to http://127.0.0.1:8000/api/books using a tool like Insomnia.

   

   

2. If you want to accept other HTTP methods like POST, PUT, or DELETE, you need to define them in the API view decorator. For example, to accept POST requests, add ['POST'] in the @api_view decorator.
