LoginView combine SuccessMessageMixin failed!

[Cihat Ertem]

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.
