Translatable columns for Rails 4, directly stored in a postgres hstore in the model table.
Inspired by Barsoom's traco.
To store translations outside the model, see Sven Fuchs' globalize3.
Say you want
Post#body to support both English and Swedish values.
Write a migration to get hstore database columns with i18n suffixes, e.g.
class CreatePosts < ActiveRecord::Migration def change create_table :posts do |t| t.hstore :title_i18n t.hstore :body_i18n t.timestamps end end end
body columns without the
_i18n suffix, Trasto will define a method with that name.
Declare these columns in the model:
class Post < ActiveRecord::Base translates :title, :body end
You can still use your accessors for
title_i18= in forms, validations and other code, but you also get:
#title: Shows the title in the current locale. If blank, falls back to default locale, then to any locale.
#title=: Assigns the title to the column for the current locale, if present.
.locales_for_column(:title): Returns an array like
[:de, :en] sorted with default locale first and then all currently available locals sorted alphabetically.
Add this to your
You might need to enable the hstore extension for your database. Create a migration containing the necessary instruction:
class EnableHstore < ActiveRecord::Migration def change enable_extension 'hstore' end end
Running the tests
bundle exec appraisal install bundle exec appraisal rake
To run only one appraisal/gemfile:
bundle exec appraisal 4.2 rake
