Conditional Middleware Processing Based on URL Pattern

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

    def __call__(self, request):
        if request.path.startswith('/api/'):
            request.is_api = True
        else:
            request.is_api = False
        response = self.get_response(request)
        return response

  1. The middleware correctly identifies API requests and attaches flag to request object

  2. The middleware should use URL routing patterns instead of path string matching

  3. Request object attributes added in middleware are not accessible in views

  4. The middleware should return different responses for API vs non-API requests

Show answer & explanation

Correct answer

The middleware correctly identifies API requests and attaches flag to request object

Explanation

The middleware conditionally marks API requests by checking URL path pattern, allowing downstream views and other middleware to handle API requests differently.
