def admin_view(self, view, cacheable=False):
        """
        Decorator to create an admin view attached to this ``AdminSite``. This
        wraps the view and provides permission checking by calling
        ``self.has_permission``.

        You'll want to use this from within ``AdminSite.get_urls()``:

            class MyAdminSite(AdminSite):

                def get_urls(self):
                    from django.conf.urls import url

                    urls = super(MyAdminSite, self).get_urls()
                    urls += [
                        url(r'^my_view/$', self.admin_view(some_view))
                    ]
                    return urls

        By default, admin_views are marked non-cacheable using the
        ``never_cache`` decorator. If the view can be safely cached, set
        cacheable=True.

                return self.create_admin_view(self.login_view)(request, *args, **kwargs)
            return view(request, *args, **kwargs)

        if not cacheable:
            inner = never_cache(inner)
        return update_wrapper(inner, view)
