I have three entities:
- Attendee (holds basic attendee information)
- Project (holds basic project information)
- Attendance (links attendees and projects and holds more information like "invited_at", "is_confirmed"...)
One attendee can attend one project only once, but can of course attend multiple projects.
When I filter by project on the attendance index page one attendee can have only one or no attendance. In this case I want to display the corresponding attendance's information (like invited_at).
But fields like attendances.invited_at show no informartion on the attendee index page.
I guess this due to the n:n relation. Because fields like attendee.firstname are displayed without a problem on the attendances index page.
How can I get the attandance extra information to display on the attendee's index page?
Ok, there is a quite obvious solution for this problem. Custom fields.
