This module allows to make registration to events with more than one attendee.

This was the unique behavior on versions 8 and 9. As it's useful for some use cases, this module allows both ways of registering attendees.

auto_awesome What this module does

AI-generated from the code · Odoo 18.0

Lets an event accept registrations for several attendees at once: each registration gets a quantity, and seat counts are calculated from those quantities instead of one seat per registration.

This module adds an option to events so that a single registration can cover more than one attendee.

  • On the event form, a new checkbox "Allow multiple attendees per registration" appears next to the time zone field. It is off by default.
  • On event registrations, a new "Quantity" field (default 1) appears in both the registration list and the registration form, right after the event field.

Business rules added by the module: - If the option is not enabled on the event, a registration cannot have a quantity greater than one; Odoo blocks it with an error message. - Once registrations with a quantity above one exist, the option cannot be switched off on that event; Odoo refuses with an error message. - For events where the option is enabled, the reserved, used, taken and available seats are recalculated by adding up the quantities of open and done registrations, instead of counting one seat per registration. Events without the option keep the standard behaviour.

The module touches the event and registration screens only (event.event and event.registration); it adds no new menus or reports.
