如何在Django的管理网站中添加“注销”功能

Question

In my Django project, I created a separate admin.py and in that file, I extend the AdminSite class as follows:

class UserAdminSite(AdminSite):
    site_header = "Admin Site"
    site_title = "Manage User and Groups"
    login_form = AuthenticationForm

def has_permission(self, request):
    return request.user.is_active and request.user.is_admin_user

But then I discovered that in that admin site, there is no link on the top left to the logout. How do I add that to the admin site?

If you are extending AdminSite you should already have a logout function,

https://github.com/django/django/blob/master/django/contrib/admin/sites.py#L349 :

@never_cache
def logout(self, request, extra_context=None):
    """
    Logs out the user for the given HttpRequest.
    This should *not* assume the user is already logged in.
    """
    from django.contrib.auth.views import logout
    defaults = {
        'current_app': self.name,
        'extra_context': dict(self.each_context(request), **(extra_context or {})),
    }
    if self.logout_template is not None:
        defaults['template_name'] = self.logout_template
    return logout(request, **defaults)

if you look at the admin site's base.html it's looking for url with the namespace admin:logout

https://github.com/django/django/blob/master/django/contrib/admin/templates/admin/base.html#L46 :

<a href="{% url 'admin:logout' %}">{% trans 'Log out' %}</a>

Are you overwriting the default admin urls.py? You can check the Django docs here for details on setting namespace.
