In Django, middleware is a lightweight plugin that processes during request and response execution. Middleware is used to perform a function in the application. The functions can be a security, session, csrf protection, authentication etc.
It must accept the get_response argument because Django initializes middleware with only it. To activate middleware, add it to the MIDDLEWARE list of the settings. Py file, 4 other middleware methods, and 3 middleware order and layering as well are a couple more items to think about.
One of the next things we wondered was: what is Django’s middleware framework?
Django’s middleware framework allows the developers to hook into the request/response processing. They allow us to alter the request/response globally on every request/response cycle.
Create a file named custom_middleware. Py (or anything which you like) and a regular Python function / class in it. You can write middleware as a function or as a class whose instances are callable. Now the final step will be to add your custom middleware in MIDDLEWARE List in settings., and py file.
Django middlewares are the right place for abstracting custom functionality that needs to alter the request/response cycle of a Django application. Keep your Django apps clean. Thanks for reading and stay tuned!
What is security middleware in Django?
For example, Security Middleware is used to maintain the security of the application. Middleware is a class that takes an argument get_response and returns a response. It must accept the get_response argument because Django initializes middleware with only it.
For example the Authentication. Middleware alters and associates the request object with a user (using sessions) for each request, which is passed on to the views. Django’s middleware has changed quiet a bit in the version 1.10. Prior to version 1.10, there were 5 hooks.
When a user makes a request from your application, a WSGI handler is instantiated, which handles the following things: Imports project’s settings. Py file and Django exception classes. Loads all the middleware classes which are written in MIDDLEWARE tuple located in settings., and py file.
