Overwrite Django's logout method

It's a good question, but first we must understand why it does not work.

When you create the logout view, what you are doing is creating a function or class that is called every time you enter that view and therefore the code that you specified is executed. But in the case of expire session at browser close, it is different why the view no longer comes into play here, django takes part in this and sends the logout when the browser is closed.

Solution

Well here I'm not so sure, but what you can do is modify directly in the django files, here I leave a link that shows the function link

You can try adding the code inside the function

Hello friend, the only thing that I have found is to do it directly from the URL in the file urls.py so:

    from django.contrib.auth import views as auth_views
    urlpatterns = [

        url(r'^$', inicio, name="inicio"),
        url(r'^login/$', auth_views.login, name='login'),
        url(r'^logout/$', auth_views.logout,  {'next_page': '/site/'}, name='logout'),

So you can direct the logout where you want, I hope it serves you.
