Как мы получаем u внутри метода login_required

Может кто-нибудь помочь мне объяснить это пошаговое выполнение, так как я использую login_required в моих URL-адресах как: -
path(
"affiliater/registers/",
login_required(views.RegistersView.as_view(), login_url='/affiliater/login/'),
name="registers"
)
