I18n::Backend::ActiveRecord

ActiveRecord model used to store actual translations to the database.

This model expects a table like the following to be already set up in your the database:

  create_table :translations do |t|
    t.string :locale
    t.string :key
    t.text   :value
    t.text   :interpolations
    t.boolean :is_proc, :default => false
  end

This model supports to named scopes :locale and :lookup. The :locale scope simply adds a condition for a given locale:

  I18n::Backend::ActiveRecord::Translation.locale(:en).all
  # => all translation records that belong to the :en locale

The :lookup scope adds a condition for looking up all translations that either start with the given keys (joined by an optionally given separator or I18n.default_separator) or that exactly have this key.

  # with translations present for :"foo.bar" and :"foo.baz"
  I18n::Backend::ActiveRecord::Translation.lookup(:foo)
  # => an array with both translation records :"foo.bar" and :"foo.baz"

  I18n::Backend::ActiveRecord::Translation.lookup([:foo, :bar])
  I18n::Backend::ActiveRecord::Translation.lookup(:"foo.bar")
  # => an array with the translation record :"foo.bar"

When the StoreProcs module was mixed into this model then Procs will be stored to the database as Ruby code and evaluated when :value is called.

  Translation = I18n::Backend::ActiveRecord::Translation
  Translation.create \
    :locale => 'en'
    :key    => 'foo'
    :value  => lambda { |key, options| 'FOO' }
  Translation.find_by_locale_and_key('en', 'foo').value
  # => 'FOO'
