Django middleware for request logging and timing

13031 views

                  import logging
import time

logger = logging.getLogger(__name__)


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

    def __call__(self, request):
        request.start_time = time.time()

        response = self.get_response(request)

        duration = time.time() - request.start_time

        logger.info(
            'request_completed',
            extra={
                'method': request.method,
                'path': request.path,
                'status': response.status_code,
                'duration_ms': round(duration * 1000, 2),
                'user': str(request.user) if request.user.is_authenticated else 'anonymous',
            }
        )

        return response

Custom middleware lets me inspect or modify every request and response. I implement both __init__ (called once at startup) and __call__ (for each request). By storing start time in the request, I can measure total processing time including view and template rendering. I log requests to a structured logger with contextual data like user, path, and duration. Middleware order matters—I place this early in MIDDLEWARE to capture total time. For production, I sample or filter to avoid log spam on high-traffic endpoints.
