How do you create a middleware in Django?

Blog Article

In Django, middleware is a framework component that processes requests and responses globally before they reach views or after they leave them. To create custom middleware, you define a Python class that implements methods such as process_request, process_response, or process_exception. For example, a simple logging middleware can be created by defining a class that prints request methods and paths inside process_request, and response statuses inside process_response. This middleware class must then be registered in the MIDDLEWARE list within settings.py by adding its module path. Once registered, Django automatically applies the middleware to every request and response. Middleware is commonly used for tasks like logging, authentication, request modifications, security enhancements, and caching, providing a powerful way to process data at a global level in a Django application.
