33357	SuccessMessageMixin doesn't work with LoginView	Cihat Ertem	Baptiste Mispelon	"I have a problem with SuccessMessageMixin, LoginView. There is no problem with CreateView:
{{{#!py
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
{{{#!py
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:
{{{#!py

urlpatterns = [

    path('admin/', admin.site.urls),
    path(, include('django.contrib.auth.urls')),
    path(, include('base.urls')),

]
}}}

the base apps urls:
{{{#!py
# 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'),
