auto_awesome What this module does
AI-generated from the code · Odoo 19.0After a sale order with event tickets is confirmed, you can change the number of attendees directly from the order line. A small edit button opens a wizard to increase or reduce the quantity and manage the related registrations.
This module adds a way to adjust the number of event attendees on a confirmed sale order, without having to cancel or recreate the order line.
On a confirmed sale order, event ticket lines show a small edit button next to the quantity. It only appears when the line is linked to an event and the order is confirmed. Clicking it opens a pop-up window showing the event, the ticket and the current quantity.
- If you increase the quantity, the line quantity is updated and Odoo opens the attendee registration screen so you can fill in the new attendees.
- If you decrease the quantity, the wizard asks you to tick exactly the attendees to remove; if the number ticked does not match the reduction, an error message stops you. The selected registrations are then deleted and the line quantity is updated.
- If you enter the same quantity, an error tells you nothing has changed.
The module touches sale.order.line, the attendee registration editor and adds a new wizard model. It also adds a view on the sale order form. No scheduled jobs or emails are added.
