Adding extra context in built-in exit mode from Django

Question

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

 def logout(request, next_page=None, template_name='registration/logged_out.html', redirect_field_name=REDIRECT_FIELD_NAME, current_app=None, extra_context=None): 

I would like to add extra_context to get rid of the 'Logged out' header that appears when I log out

so i am trying to do this in my confl url:

 (r'^accounts/logout/$', logout(extra_context={'title':'something else'}) ), 

but then I get this error: logout () takes at least 1 argument without the keyword (0) what am I doing wrong? ps: when i do

 (r'^accounts/logout/$', logout ), 

it works, but then I get the text "Recorded" ...

Thanks Fred

Answer 1

When you write logout(extra_context={'title':'something else'}) , you actually call logout directly in the URLconf, which will not work. Any URLconf tuple can have an optional third element, which must be a dictionary of additional keyword arguments to go to the view function .

 (r'^accounts/logout/$', logout, {'extra_context':{'title':'something else'}}), 

Alternatively, you can write your own view that causes logout pass any arguments you want — typically how you “extend” general views based on functions in more complex cases.

Adding my results for django 2.0, as the previous answer in this thread no longer works for the latest version of django.

Since 2.0, the correct way to add a URL to your urls.py file is with 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 .as_view () function is highlighted in this code snippet. Django 2.0 implements auth views as classes. For more information, see Authentication Documentation.

Then you “convert” the class into a view using `.as_view (), and you can pass the class attributes defined in the source code as named parameters.

Passing to extra_context (None by default) automatically provides 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 other class attributes that you can pass to LogoutView and other auth view classes.
