module Mobility
module Backend
=begin
Implements the {Mobility::Backend::Column} backend for ActiveRecord models.
You can use the +mobility:translations+ generator to create a migration adding
translatable columns to the model table with:
rails generate mobility:translations post title:string
The generated migration will add columns +title_<locale>+ for every locale in
+I18n.available_locales+. (The generator can be run again to add new attributes
or locales.)
@note This backend disables the +locale_accessors+ option, which would
otherwise interfere with column methods.
@example
class Post < ActiveRecord::Base
translates :title, backend: :column
end
Mobility.locale = :en
post = Post.create(title: "foo")
post.title
#=> "foo"
post.title_en
#=> "foo"
=end
class ActiveRecord::Column
include ActiveRecord
include Column
require 'mobility/backend/active_record/column/query_methods'
# @!group Backend Accessors
# @!macro backend_reader
def read(locale, **_)
model.read_attribute(column(locale))
end
# @!group Backend Accessors
# @!macro backend_writer
def write(locale, value, **_)
model.send(:write_attribute, column(locale), value)
end
# @!group Backend Configuration
def self.configure(options)
options[:locale_accessors] = false
end
