I have made a certain app in Django, and I know that Django Rest Framework is used for building APIs. However, when I started to read about Django Rest Framework on their website. Each and every thing in API Guide(like request, response, views etc).talks about it is superior than Django (request, response, views etc.)

The thing I am not understanding whether these API's will replace my existing Django models, views etc. or how can I use them differently in my existing Django code?

I am quite familiar with Django, but not able to understand what exactly what Django Rest Framework is even after spending some time on it.(I know it is used for APIs). Also, do I actually need an API? My app is able to send data to server without API so in what case I would need an API.

Django Rest Framework makes it easy to use your Django Server as an REST API.

REST stands for "representational state transfer" and API stands for application programming interface.

You can build a restful api using regular Django, but it will be very tidious. DRF makes everything easy. For comparison, here is simple GET-view using just regular Django, and one using Django Rest Framework:

Regular:

from django.core.serializers import serialize
from django.http import HttpResponse


class SerializedListView(View):
    def get(self, request, *args, **kwargs):
        qs = MyObj.objects.all()
        json_data = serialize("json", qs, fields=('my_field', 'my_other_field'))
        return HttpResponse(json_data, content_type='application/json')

And with DRF this becomes:

from rest_framework import generics


class MyObjListCreateAPIView(generics.ListCreateAPIView):
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]
    serializer_class = MyObjSerializer

Note that with DRF you easily have list and create views as well as authentication.

Django REST framework: Home, the virtual environment pip install django pip install djangorestframework # Set up a new project with a single application django-admin startproject tutorial . Django Rest Framework makes it easy to use your Django Server as an REST API. REST stands for "representational state transfer" and API stands for application programming interface. You can build a restful api using regular Django, but it will be very tidious. DRF makes everything easy.

Whether you need an api depends on what you want to do. For example, if you want to access everything in your Django models from a mobile device AND a web-app, you would want to use DRF.

Why? Consider the case that you are developing an iOS app that users can sign into and you want to use Django as your backend. If you also want to have a website that they can use to change around their app's profile information (say, update their email address or upload a picture), you would need a way to share the information in your Django models with both a website and the iOS device. How can this be done? By giving the user the ability to create/read/update/delete data by simply telling it a url to go to. Now, if you want to access information from the model you can do it from multiple devices, since any device can visit a url.

However, if you're just building a simple webapp/webpage and keep it all in one place, you can just use straight Django.

Side note: it's a pretty popular opinion that you should try to separate your frontend from your backend as much as possible. In this case, if you want to use some frontend development framework like React, Angular, or Vue, it's gonna get messy trying to include all those resources in the Django template pages even if you only want a simple web app/web page. In this case, you would use DRF to set up your backend, and just hit the urls from the frontend using a tool like axios. In this scenario, your frontend would likely be hosted on something like Node.

Again, what you decide to use really just depends on what you want out of your app/site and how comfortable you are with each tool.

Quickstart, Django Rest Framework makes it easy to use your Django Server as an REST API. REST stands for "representational state transfer" and API  Django Rest Framework gives us several options for setting permissions: at a project-level, view level, or object level. In this case we will implement the last option and create a custom permission we can add to our SnippetDetail view class. Create a new permissions.py file.

Basic purpose of DRF is to provide apis. Now Gentleman, api is your touch point in app. Imagine a project where you have django wizard and one on your team is javascript expert and you want to develop mobile app. Javascript expert talks about web elements, threading and django expert talks templates and ORM, now what? Api is your answer. Let django wiz give apis and json and let j wiz do his front end magic. Simplest answer I can think of.

Django or Django Rest Framework, Django and DRF( Django Rest Framework ) are different in the way they are being used. If you want to create a web application django will be helpful for that​  I admit, “Configurable API” sounds a bit unusual at first. In fact, I mean exactly what it says. The goal of this post is to show how to create an HTTP API with Django so that users or administrators can configure the output of the interface without restarting the application.

Comments
  • Not the right place to ask. But I have same question.
  • They are designed to work together. DRF can build on top of your Django models (and Django authentication etc) - you use it instead of plain Django views in the places where you want API endpoints
  • @Rahul Yeah it is quite confusing(difference between two and need for DRF)
  • "also do I actually need an API" ...if you don't know whether you need an API you probably don't need an API
  • it shows you how the concepts fit together by giving a practical example... you can see the Django parts and the DRF parts and also goes from basic to a bit more advanced. I suggest to actually read it and try and understand what you are reading
  • Your second example is incomplete as MyObjSerializer has to be defined somewhere, so it's not as "easy" as the example suggests (you can't get away without listing model fields etc somewhere). It'd be better to make the point that you can reuse the custom serializer in multiple views though. So DRF helps with re-using code in addition to autogenerating a bunch of endpoints, format options, versioning...
  • I like the answer, it shows complexity of code, but I am puzzled about why Flask is not considered as a top framework for its simplicity. Example, What does it make Flask be less considered in jobs requirements VS popularity of django or DRF ?
  • This doesn't really explain why prefer DRF over plain Django. You imply with "By giving the user the ability to create/read/update/delete data by simply telling it a url to go to" that DRF can do it but Django can't, which of course is false. You also suggest Django doesn't let you separate front and backend, also false. I guess my point is you don't really explain how DRF helps with these versus just doing it in plain Django, which was the whole point of the question.
