has_one relationships don't have id only getters or setters. For example 
engineer.laptop_id or engineer.laptop_id= are not implemented in Rails 5. 
Is there any reason for this?

class Engineer < ActiveRecord::Base
  belongs_to :team
  has_one :laptop
  has_many :tasks
end


engineer = Engineer.first


# Getters
engineer.team_id # works
engineer.laptop_id # doesnt work (Not implemented)
engineer.task_ids # work


# Same issue with setters too.

Thanks
