Halaman Tamu

Termasuk bagian Formulir dalam perjalanan Django di Coddy. Pelajaran 19 dari 20.

Penyelenggara menginginkan halaman untuk setiap acara yang hanya menampilkan tamu acaranya, sebagai tempat untuk mengelola mereka. Kamu sudah mengetahui setiap bagiannya: URL dengan pk acara, view yang menemukan acara tersebut, dan perulangan template untuk event.rsvps.all.

Template guest_list.html sudah disiapkan untukmu, tetapi daftarnya masih kosong. Daftar tamu hanya terkait dengan satu acara, jadi ambil tamunya melalui acara tersebut, jangan dari semua RSVP.

Tantangan

Sedang

/events/<pk>/guests/, nama URL guests, menampilkan daftar tamu acara beserta email mereka di guest_list.html.
Setiap halaman acara memiliki tautan ke halaman ini dengan teks Manage guests.

Tekan Jalankan, buka Friday Jazz Night, lalu tekan Manage guests.
