 I have a problem with SuccessMessageMixin, LoginView. There is no problem
 with CreateView:
 class CreateRoom(SuccessMessageMixin, CreateView):
     template_name = 'base/room_form.html'
     form_class = RoomForm
     success_url = reverse_lazy('home')
     success_message = 'Message'

 I can capture and use 'Message' in template but with LoginView
 class Login(SuccessMessageMixin, LoginView):
     template_name = 'registration/login.html'
     success_url = reverse_lazy('home')
     success_message = 'Message!!!'

 I can not capture 'Message' with LoginView.

 project urls:

 urlpatterns = [
     path('admin/', admin.site.urls),
     path('', include('django.contrib.auth.urls')),
     path('', include('base.urls')),
 ]

 the base apps urls:
 # app_name = 'base'

 urlpatterns = [
     path('', views.Home.as_view(), name='home'),
     path('room/<int:pk>/', views.Room.as_view(), name='room'),
     path('create-room/', views.CreateRoom.as_view(), name='create-room'),
     path('update-room/<int:pk>/', views.UpdateRoom.as_view(model=Room),
 name='update-room'),
     path('delete-room/<int:pk>/', views.DeleteRoom.as_view(model=Room),
 name='delete-room'),
     path('login/', views.Login.as_view(), name='login')
