Детальное описание представлений-классов Django (Class-Based Views) Multiple inheritance and mixin classes in Python. By Leonardo Giordani 27/03/2020 08/04/2020 algorithms Django OOP Python Python3 Share on: Twitter LinkedIn HackerNews Email Reddit I recently revisited three old posts on Django class-based views that I wrote for this blog, updating them to Django 3.0 (you can find them here) and noticed once again that the code base uses mixin classes to AccessMixin in Django 1.9. Abstract CBV mixin that gives access mixins the same customizable functionality. Try DJANGO Tutorial series is here to teach you Django bit by bit.

Lets go through some lifecycle methods in order: 1. mixins override dispatch if they need to check if user if logged in, has permission. This is one of the first methods called and view determines which request method (get, post etc) is used. 2. mixins override get_context_data() to add new data to context. This method passes keyword arguments to the template context.

By default the mixin will return a permanent (301) redirect to the https verison of the current url. Optionally you can set raise_exception=True and a 404 will be raised.

Limiting access to certain views¶ For increased security views can be limited to two-factor-enabled users. This allows you to secure certain parts of the website. Doing so requires a decorator, class mixin or a custom inspection of a user’s session.

Optionally you can set raise_exception=True and a 404 will be raised. Django’s built-in class-based views provide a lot of functionality, but some of it you may want to use separately. For instance, you may want to write a view that renders a template to make the HTTP response, but you can’t use TemplateView; perhaps you need to render a template only on POST, with GET doing something else entirely. Access Mixins ¶ These mixins all control a user’s access to a given view. Since they all extend the AccessMixin, the implement a common API that includes the following class attributes: login_url = settings.LOGIN_URL redirect_field_name = REDIRECT_FIELD_NAME raise_exception = False from django.contrib.auth.mixins import PermissionRequiredMixin class MyView(PermissionRequiredMixin, View): permission_required = 'polls.can_vote' permission_required = ('polls.can_open', 'polls.can_edit') Theses mixin classes all inherit from a generic AccessMixin which makes rolling your own access-based mixins easy.

contrib. auth. mixins import LoginRequiredMixin class MyView (LoginRequiredMixin, View): * The :attr:`permission_required ` attribute supports a string (defining one permission) or a list/tuple of: strings (defining multiple permissions) that need to be fulfilled to grant: access. * The new :attr:`~django.contrib.auth.mixins.AccessMixin.permission_denied_message` attribute allows I've been using Mixins lately to DRY-ly make certain behavior available to several different Django models. If you're not familiar with mixins, there's a great discussion over on StackOverflow.

How those other classes gain access to the mixin's methods depends on the language. Mixins are sometimes described as being "included" rather than "inherited".

The UserManager is a custom model manager that provides the create_user() and create_superuser() methods used in Django. Danger Improved Users’ custom UserManager is intended to work with subclasses of EmailAuthMixin , and will likely not work with your User subclass if you are using a different field for your username.

I've been huge fan of Django's class-based views (CBVs) since I first tried them out in Django 1.4. While they're much more complicated then the classic function based views, once you understand how they work, they're much more powerful, flexible and allow for DRYer code.

If you want to get the currently logged-in user and use it—e.g at the top of every template, in class-based view it could be hard to achive.
