  # Very purposefully using #length here. If you use #empty? or #count and
  # the relation isn't yet loaded, it's going to trigger another query.
  # Since we're going to need to map over each of the results in order to
  # serialize it anyway, it's better just to load it now and avoid the
  # extra query.
