Posted by Colin Law (Guest) on 2013-11-12 14:56 That does not make sense, in your original post you implied minisection belongs_to subsection, and so on up through the heirarchy. Therefore any particular minisection is associated with only one subsection, section, chapter and so on. So, original question... Having several tables related by "has_many" and would like to find the "distant children". eg: Tables: Subjects Books Chapters Sections Subsections Minisections They are all related heirarchichally, so book for example is related to subjects and chapters the following way. All are related the same way. Book belongs_to :subject has_many :chapters So if I have the subject id, how can I find all the Minisections belonging to that subject without adding all related table id's in each table? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
