FormTranslation

It uses ActiveRecord::Store to store language specific values and adds tabs to your forms for each language.

Add this line to your application's Gemfile:

gem 'form_translation', github: 'Crunch09/form_translation'

And then execute:

$ bundle
$ rails g form_translation:install

• In your model include `FormTranslation::ForModel* and specify which attributes should be translated.

class Article < ActiveRecord::Base
      include FormTranslation::ForModel

      translate_me :subject, :body
end

• Within your simple_form-Form specify where to put your translation-tabs with a languagify block.

<%= simple_form_for(@article) do |f| %>
      <div class="form-inputs">
        <%= f.input :date %>
      </div>
      <div>
        <%= f.languagify do |l| %>
          <%= l.input :subject %>
          <%= l.input :body %>
        <% end %>
      </div>
      <div class="form-actions">
        <%= f.button :submit %>
      </div>
<% end %>

Lastly, make sure to add the translated attributes to your permitted parameters so they can be stored. The convention for the attribute name is as follows: language_shortname_attribute_name

def article_params
  params.require(:article).permit(:subject, :body, :de_subject, :de_body)
end
