Sebuah tampilan berdasarkan-kelas disebarkan kedalam corak URL menggunakan metodekelas as_view():

\n
Code
urlpatterns = [\n    path('view/', MyView.as_view(size=42)),\n]\n
\n\n

Argumen dilewatkan kedalam as_view() akan diberikan ke atas instance yang digunakan untuk melayani sebuah permintaan. Menggunakan contoh sebelumnya, ini berarti bahwa setiap permintaan pada MyView dapat menggunakan self.size. Argumen-argumen harus berhubungan ke atribut-atribut yang sudah ada pada kelas (mengembalikan True pada pemeriksaan hasattr).
