How I can throttle only the POST method in this views – Python

The Problem:

In a Django REST framework application, there are two views defined: a POST view and a GET view. The goal is to implement throttling specifically for the POST view while keeping the GET view unthrottled. How can this be achieved using the appropriate Django REST framework components?

The Solutions:

Solution 1: Use @throttle_classes decorator on specific view methods

To throttle only the POST method in a specific view, you can use the `@throttle_classes` decorator on the `post()` method of the view. This will apply the throttling to only the POST method, while leaving the GET method unthrottled.

from rest_framework.decorators import throttle_classes
from rest_framework.throttling import UserRateThrottle

class ExampleView(APIView):

    @throttle_classes([UserRateThrottle])
    def post(self, request, format=None):
        content = {
            'status': 'request was permitted'
        }
        return Response(content)

    def get(self, request, format=None):
        content = {
            'status': 'request was permitted'
        }
        return Response(content)

In this example, the `@throttle_classes([UserRateThrottle])` decorator is applied to the `post()` method of the `ExampleView` class. This means that the POST method will be throttled according to the rules defined in the `UserRateThrottle` class, while the GET method will not be throttled.

Solution 3: Override the `get_throttles` method

By default, `throttle_classes` throttles all methods. If you want to limit it to only throttle the POST method in your Django view you need to change the get_throttles method. By modifying get_throttles, you can choose which methods to throttle.

See the example code below:

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.throttling import UserRateThrottle

class ExampleView(APIView):
    # No need to declare throttle_classes here

    def get_throttles(self):
        if self.request.method == 'POST':
            # Apply throttling only for POST requests
            return [UserRateThrottle()]
        return []  # Return an empty list for other methods

    def get(self, request, format=None):
        content = {
            'status': 'GET request was permitted'
        }
        return Response(content)

    def post(self, request, format=None):
        content = {
            'status': 'POST request was permitted'
        }
        return Response(content)

In this example, the get_throttles method is overridden to apply the UserRateThrottle only to POST requests. It returns an empty list for GET requests, meaning no throttling will be applied for this request and it will remain unaffected.
