What's the easiest way to add translation capabilities to an existing model and automatically migrate the existing records?
The globalize gem provides a method create_translation_table with an option migrate_data: true, is there an equivalent for mobility?
The only workaround I found when working with the gem using the :key_value Strategy
is to create a migration for each table and re-saving the value of the column using [:column_name]
Example:
If we Have a Post Table and I want to add it's name attribute to translations:
The Mobility migration(s) must be executed and post.rb must include:
# post.rb
class Post < ApplicationRecord
extend Mobility
translates :name, type: :string
end
Then update the records to reflect the value of the default language (assuming application.rb has config.i18n.default_locale = :de and initializers/mobility.rb defines locale_accessors [:de, :en, :sl]
Post.all.each do |post|
post.update(name_de: post[:name])
end
Then verify:
> Post.last.name_de
> Post.last.name_en
> Post.last.name_sl
