#segments ⇒ Object

virtual has_many association has_many :segments won’t work because there’s no general way to specify the correct conditions even if you get clever with it, like has_many :segments,

:class_name => 'FlightSegment',
:foreign_key => 'origin_airport_id',
:conditions => 'flight_segments.destination_airport_id = #{id}'

you get queries like “‘flight_segments`.origin_airport_id = 3654 AND (flight_segments.destination_airport_id = 3654))” in which you notice the AND which must be an OR and you can’t just do finder_sql, because that breaks any other :select
