A Guest Page

Part of the Forms section of Coddy's Django journey. Lesson 19 of 20.

The organiser wants a page for each event that lists only its guests, a place to manage them. You know every piece: a URL with the event's pk, a view that finds the event, and a template loop over event.rsvps.all.

The template guest_list.html is started for you; its list is empty. A guest list belongs to one event, so read the guests through the event, never from all the RSVPs.

Challenge

Medium

/events/<pk>/guests/, URL name guests, lists the event's guests with their emails, in guest_list.html.
Each event page links to it with Manage guests.

Press Run, open Friday Jazz Night and press Manage guests.
