I cannot seem to get through associations working properly on tables that have non standard primary keys.
class Address < ActiveRecord::Base set_primary_key "address_id" has_many :investor_addresses has_many :investors, :through => :investor_addresses, :source => :investor end
class Investor < ActiveRecord::Base set_primary_key "pid" has_many :investor_addresses has_many :addresses, :through => :investor_addresses, :source => :address end
class InvestorAddress < ActiveRecord::Base set_primary_key "investor_address_id" belongs_to :investor, :foreign_key => "pid" belongs_to :address, :foreign_key => "address_id" end
The Investors table has primary key pid. The Addresses table has primary key address_id. The investor_addresses table has a primary key investor_address and also columns pid and address_id.
To me this should work but when I do: i = Investor.find(6493) i.addresses
Active record seems to think the investor_addresses table has a column called investor_id. Why wont it use pid?
