Adding extra_context in Django logout built-in view

Question

In django/contrib/auth/views.py there is the definition of the logout view :

def logout(request, next_page=None,
       template_name=\'registration/logged_o         


        

Answer 1

Adding my findings for django 2.0 as the previous answer on this thread no longer works for the most recent django version.

With 2.0, the proper way of adding a URL to your urls.py file is by using path():

from django.urls import path
from django.contrib.auth import views as auth_views

path('accounts/logout/', auth_views.LogoutView.as_view(
  extra_context={'foo':'bar'}
)),

The code snippet to highlight here is the .as_view() function. Django 2.0 implements auth views as classes. You can read more about this in the Authentication Views documentation

You then "convert" the class to a view using `.as_view() and you are able to pass in any class attributes defined in the source code as named parameters.

Passing in extra_context (which defaults to None) automatically exposes these context variables to your templates.

You can access the source code for LogoutView by following this python path: django.contrib.auth.views

Here you can see the other class attributes you can pass into LogoutView and the other auth view classes.
