Activerecord::HasOneDefaults
Allows ActiveRecord to default has_one relationships.
Installation
Add this line to your application's Gemfile:
gem 'activerecord-has_one_defaults'
And then execute:
$ bundle
Or install it yourself as:
$ gem install activerecord-has_one_defaults
Usage
When declaring a has_one relationship, either pass true, or a hash, as the
:default
option. When the association is accssed, it will automatically be
built.
class User < ActiveRecord::Base
has_one :head, :default => {:eyes => 4, :ears => 6, :noses => 3}
has_one :neck, :default => true
has_one :address, :default => false
has_one :profile
has_one :left_foot, :default => {:side => :left}, :class_name => "Foot"
accepts_nested_attributes_for :left_foot
end
User.new.head.eyes
# 4
User.new.neck
# #<Neck:0x007fb2f4c68fc8> {}
User.new.address
# nil
User.new.profile
# nil
u = User.new
u.left_foot_attributes => {:size => 12}
u.left_foot.size
# 12
