I'm trying using STI to implement a hiearchy similar to this: script/generate scaffold name:string type:string
class Person < ActiveRecord::Base; end class Customer < Person; end class Employee < Person; end class Developer < Employee; end I.e., there are two levels of inheritance (Developer < Employee < Person). When creating a Customer, Rails understands it's a Person, but if I create a Developer, Rails 'tends to forget' it's an Employee. In other words: $ script/console >> Developer.create :name=>'Bob' => #<Developer id: 1, name: "Bob", type: "Developer", created_at: "2009-05-08 09:59:58", updated_at: "2009-05-08 09:59:58"> >> exit $ script/console >> Employee.find :all => [] >> Person.find :all => [#<Developer id: 1, name: "Bob", type: "Developer", created_at: "2009-05-08 09:59:58", updated_at: "2009-05-08 09:59:58">] Worst of all, if I change the order of the 'find' statements, things work: $ script/console >> Person.find :all => [#<Developer id: 1, name: "Bob", type: "Developer", created_at: "2009-05-08 09:59:58", updated_at: "2009-05-08 09:59:58">] >> Employee.find :all => [#<Developer id: 1, name: "Bob", type: "Developer", created_at: "2009-05-08 09:59:58", updated_at: "2009-05-08 09:59:58">] Maybe this has to do with some caching stuff... any ideas? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
