Reference type field with derived display field

Question

In ng-admin I am able to add a field of type reference and display the name of the referenced entity by

nga.field('schedule', 'reference')
  .targetEntity(schedule)
  .targetField(nga.field('name'))
  .label('Schedule'),

Is it possible to display a derived field of the referenced entity, say name (id)?

I tried using .template() with no luck.

You'll have to use map(), as seen in the Posters galore demo:

nga.field('schedule', 'reference')
  .targetEntity(schedule)
  .targetField(nga.field('name').map((v, e) => e.name + ' (' + e.id + ')'))
  .label('Schedule')
