Introduction: Django, a high-level Python web framework, encourages rapid development and clean, pragmatic design. It is built by experienced developers and takes care of much of the hassle of web development, so you can focus on writing your app without needing to reinvent the wheel. In this blog post, we will delve into some of the advanced topics in Django that can help you take your Django skills to the next level.
Middleware: Middleware is a series of hooks into Django’s request/response processing. It’s a light, low-level plugin system for globally altering Django’s input or output. Each middleware component is responsible for doing some specific function. For example, Django includes a middleware component, AuthenticationMiddleware, that associates users with requests using sessions.
Custom User Model: Django comes with a built-in User model for authentication. However, the official Django documentation highly recommends using a custom user model for new projects. The reason is if you want to make any changes to the User model down the road--like adding extra fields--using a custom user model from the beginning makes this quite easy.
Django Signals: Signals are used for allowing certain senders to notify a set of receivers when certain actions have taken place. They're used in Django's model system to allow certain bits of code to be plugged into the save process, or the deletion process, etc.
Django REST Framework: Django REST Framework, a powerful and flexible toolkit for building Web APIs, is a must-know for any serious Django developer. Some reasons you might want to use REST framework: The Web browsable API is a huge usability win for your developers, Authentication policies including packages for OAuth1a and OAuth2, Serialization that supports both ORM and non-ORM data sources, etc.
