Multiple Associations With The Same Object
...ject which has multiple Contacts
(has_many/belongs_to) I would like one of the contacts to be the
primary contact. What''s the best way to do this? Right now I have:
create table companies (
id int not null auto_increment,
name varchar(50) not null,
primary_id int null,
constraint fk_company_primary_contact foreign key (primary_id)
references contacts(id),
primary key (id)
);
create table contacts (
id int not null auto_increment,
name varchar(100) not null,
company_id int not null,
primary key (id)
);
class Company < ActiveRecord::Base
has_many :contacts
has_one :primary_contact,...
