steps for creating complex relations between tables

Here (http://allaboutruby.wordpress.com/2009/08/08/5-minute-project-in-rails/) we can see how to create 1-m relation between tables, but what steps should I do to create for example the next kind of the relations between tables:

http://docs.oracle.com/cd/E14373_01/appdev.32/e13363/issue_track_obj.htm

To simplify, just how to create the relation where user can have several created by him bugs and can be assigned to the several bugs created by other users.

Thanks.

First, you need two columns on bugs table, creator_id and assignee_id. Then you just create following relationships:

class User < ActiveRecord::Base
  has_many :created_bugs, :class_name => 'Bug', :foreign_key => :creator_id
  has_many :assigned_bugs, :class_name => 'Bug', :foreign_key => :assignee_id
end

class Bug < ActiveRecord::Base
  belongs_to :creator, :class_name => 'User'
  belongs_to :assignee, :class_name => 'User'
end
