Modeling polymorphic has_many :through
A user creates Spaces (rooms), Items (things), and Profiles (people).
Reservations are used to schedule times when these three models are in use and cannot be used elsewhere.
Since the modeling of a thing that can only be in use in one place/activity is common to Spaces, Items, and Profiles, this common functionality makes up the polymorphic model Resource.
Reservation
belongs_to :manager, :class_name => "Profile"
has_many :reservation_lines, :before_add => :set_nest, :dependent => :destroy
has_many :profiles, :through => :reservation_lines, :source => :reservable, :source_type => 'Profile'
has_many :spaces, :through => :reservation_lines, :source => :reservable, :source_type => 'Space'
