This gem aims to store translations in a JSON field on the parent model. It is designed to show all translations on one form, the idea is for an administrator to see and change all translations on a single form. Also designed to have very little overhead in terms of effects on the database and parent model.
- Stores translations in a single json field on the parent
- Translates back to original column by default
- Adds decorator to load these translations on form
Add gem to your Gemfile.
gem 'json_translations'Generate a migration which will add a translation column to the object. In our example we will translate title on a Post
$ rails g migration adding_title_translations_to_posts title_translations:jsonb
Be sure in this migration file to add
null: true, default: {}
Run the migration(s).
$ rake db:migrate
Then in your model add has_translations(:title)
In your application.rb file be sure to have set
config.i18n.available_locales = %i[en fr nl sv kr]
To whatever locales you have in your app
The gem comes with a handy form helper which can be used like
<%= form_with(model: todo_list, local: true) do |form| %>
<%= form.label :description %>
<%= form.text_area :description %>
<%= form.fields_for JsonTranslations::TranslationsFormDecorator.new(@todo_list.description_translations) do |translations_form| %>
<% JsonTranslations::TranslationsFormDecorator.available_locales.each do |locale| %>
<%= form.label locale %>
<%= translations_form.text_area locale %>
<% end %>
<% end %>
<% end %>
