Models
All events-domain models live in shared/models/:
| Model | Description |
|---|---|
| Calendar | Container for entries, scoped to a page via container_type + container_id |
| CalendarEntry | A bookable event/time slot with state (pending/ordered/provisional) and cost |
| CalendarSlot | Recurring time bands (day-of-week + time range) within a calendar |
| TicketType | Named ticket categories with price and count |
| Ticket | Individual ticket with unique code, state, and order_id (plain integer, no FK) |
| CalendarEntryPost | Junction linking entries to content via content_type + content_id |
order_id on CalendarEntry and Ticket is a plain integer column — no FK constraint to the orders table. The cart app writes these values via service calls, not directly.
