An update_call of the item_classification
Processing ItemClassificationsController#update (for 127.0.0.1 at 2015-03-23 11:15:54) [PUT]
Parameters: {"_method"=>"put", "commit"=>"Update", "action"=>"update", "controller"=>"item_classifications", "id"=>"4", "item_classification"=>{"title_translation"=>{"value"=>"This is a title", "locale_id"=>"2"}}} 


Example of the problem:

>> item_classification = ItemClassification.find(4)
=> #<ItemClassification id: 4, previous_level_id: 0, level: 1, name: "Objects", permalink: "objects", position: 5, items_count: 4802, description: "a description", enabled: true,...">
>> item_classification.build_title_translation(:value => 'This is a title', :locale_id => 2)
#<TitleTranslation id: nil, locale_id: 2, key: "metatags.titles.item_classification_4.title", value: "This is a title", updated_at: nil>
>> item_classification.save
=> true
>> item_classification.title_translation
=> #<TitleTranslation id: 10329, locale_id: 2, key: 4, value: "Prodotti per bambini", updated_at: "2015-03-23 10:25:23">


What am I doing wrong?

item_classification.rb

class ItemClassification < ActiveRecord::Base
  has_one :title_translation, :foreign_key => 'key', :primary_key => :custom_title_key, :conditions => ['locale_id = 2']
 
  accepts_nested_attributes_for :title_translation
 
  private
  def custom_title_key
    "metatags.titles.item_classification_#{id}.title"
  end
end

schema.rb

create_table "TitleTranslation", :force => true do |t|
  t.integer "locale_id"
  t.string "key"
  t.text "value"
  t.datetime "updated_at"
end
 
create_table "item_classifications", :force => true do |t|
  t.integer "previous_level_id"
  t.integer "level"
  t.string "name"
  t.string "permalink"
  t.integer "position"
  t.integer "items_count", :default => 0
  t.text "description"
  t.boolean "enabled"
end

title_trnaslation.rb

class TitleTranslation < ActiveRecord::Base
  belongs_to :item_classification, :foreign_key => 'key', :primary_key => :custom_title_key
 
  attr_accessible :item_classification
 
  def custom_title_key
    "metatags.titles.item_classification_#{item_classification.id}.title"
  end
end
