Unique Partner per Event, Combined With Event Sales

This module avoids duplicates when you confirm several sale orders for a same customer and event.

In case you sell different ticket types, the duplicate is however allowed, but not the combination of event + partner + ticket.


To use this module, you need to:

  1. Go to Marketing > Events > Create.
  2. Enable Forbid duplicates.
  3. Try to create 2 registrations for the same partner and ticket in this event.
  4. You cannot.
  5. Go to Sales > Sales > Sales Orders.
  6. Create a new sale order for customer "A".
  7. Add a new line with:
    • Product: Choose a event ticket product.
    • Event: Choose an event for that product.
    • Ticket: Choose a ticket type if you want.
    • Quantity: 1.
  8. Confirm the sale order.
  9. Enter the event and check it has 1 registration with 1 seat.
  10. Go back to the sale order, duplicate it and confirm it.
  11. Go back to the event again, it has 1 registration with 2 seats.
