Subject: Re: Basic Rails Database Foreign Key question

In the future, the rails mailing list would be a better place to post
this. This time, here's a solution:

# problem.rb

class Problem < ActiveRecord::Base
  belongs_to :submitter, :class_name => 'Person', :foreign_key =>
'submitted_id'
  belongs_to :assigned_to, :class_name => 'Person', :foreign_key =>
'assigned_to_id'
end

# end

look at
http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html
for full details. You can find the answer to almost every question in
the excellent API documentation available at http://api.rubyonrails.org
