I've got a content type of "Course" with entity references to users for Professor, TA, and Designer. Each user can be any of the three roles for any course.
I've got a View that shows, for the logged-in user, what courses they are the professor, OR TA, OR designer for.
What I'd like to add to that View is a column that tells the user which role they play in the course - or, in Drupal terms - which entity reference field their account is referenced in. I'd like to do this with exactly one column in the view.
The view already has Relationships from the Course to each of the referenced entities - but I am not sure how to get the conditional into a single column.
Is there a way to accomplish this with the Drupal 7 Views features, or do I need to re-write a column...?
