How can I implement advanced rate limiting in Django?

How can I implement advanced rate limiting in Django?

You can use Django's middleware to create custom rate limiting. Would you like a code example?

Yes, please provide a code example for a custom middleware.

Here's a simple example:

from django.core.cache import cache
from django.http import JsonResponse

class RateLimitMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        ip = request.META['REMOTE_ADDR']
        key = f'rate_limit_{ip}'
        requests = cache.get(key, 0)

        if requests >= 100:
            return JsonResponse({'error': 'Too many requests'}, status=429)

        cache.set(key, requests + 1, timeout=60)
        return self.get_response(request)

This middleware limits requests to 100 per minute per IP.

How can I customize the limit based on user roles?

You can modify the middleware to check user roles and set different limits accordingly. Would you like to see that?
