- Update liked_by? to return false if member is nil and use likes.exists?(member_id: member.id) instead of allocating login name arrays. - Simplify liked_by_members_names to use members.pluck(:login_name). - Update app/views/photos/_likes.html.haml to use photo.liked_by?(current_member). - Add unit tests for liked_by? in spec/models/like_spec.rb.
