This module is intended for backend use only, and extends the functionality of events to avoid duplicating attendees.

It is designed to work alongside partner_event (which is a dependency), and it is advisable to enable it by clicking on Create Partners in registration; this way it will create new partners or will match existing ones, but at the same time will avoid creating duplicates from partners already existing.

Table of contents


  1. Go to Events and choose an event or create a new one.
  2. Enable Forbid Duplicates.
  3. Go to Attendees.
  4. Create a new attendee.
  5. If you try to fill successive attendees with the same contact filled out in the “Attendee Partner” field, the system won’t allow it. That can happen for example if the same email is used several times.

Known issues / Roadmap

  • This module is intended for backend use, so the validation error is enough to show the user what is wrong,
  • When website_event is installed, and public users try to register more than one attendee, this will trigger a validation error as the attendee partner is duplicated. The error shown is 500 internal server error.
  • It would be necessary to have a new module which depends on website_event plus this one to prevent said issue.
  • Another problem would arise when used with event_sale module, because it would try to use “Sale Order” contact as attendee and that will lead to the issue of duplicated attendees if trying to buy access to the same event more than once.
