# Multilingual content

This is not an official feature yet but until we add it with all the bells and whistles you can use this guide to monkey patch it into your app.

We pushed some code to take in the set_locale param and set the I18n.locale and I18n.default_locale so all subsequent requests will use that locale.

def set_locale
  I18n.locale = params[:set_locale] || I18n.default_locale

  I18n.default_locale = I18n.locale
end

# Install the mobility gem

Follow the install instructions here (opens new window). A brief introduction below (but follow their guid for best results)

  • add the gem to your Gemfile gem 'mobility', '~> 1.2.5'
  • bundle install
  • install mobility rails generate mobility:install
  • update the backend (like in the guide) backend :key_value, type: :string
  • add mobility to your model extend Mobility
  • add translatable field translates :name
  • 🙌 that's it. The content should be translatable now.

# Add the language switcher

Before v 2.3.0

First you need to eject the _profile_dropdown partial using this command bin/rails generate avo:eject :profile_dropdown. In that partail add the languages you need to support like so:

<!-- Before -->
<% destroy_user_session_path = "destroy_#{Avo.configuration.current_user_resource_name}_session_path".to_sym %>

<div <% if main_app.respond_to?(destroy_user_session_path) %> data-controller="toggle-panel" <% end %>>
  <a href="javascript:void(0);" class="flex items-center cursor-pointer font-semibold text-gray-700" data-action="click->toggle-panel#togglePanel">
    <% if _current_user.respond_to?(:avatar) &&  _current_user.avatar.present? %>
      <%= image_tag _current_user.avatar, class: "h-12 rounded-full border-4 border-white mr-1" %>
    <% end %>
    <% if _current_user.respond_to?(:name) && _current_user.name.present? %>
      <%= _current_user.name %>
    <% elsif _current_user.respond_to?(:email) && _current_user.email.present? %>
      <%= _current_user.email %>
    <% else %>
      Avo user
    <% end %>
    <% if main_app.respond_to?(destroy_user_session_path) %>
      <%= svg 'chevron-down', class: "ml-1 h-4" %>
    <% end %>
  </a>

  <% if main_app.respond_to?(destroy_user_session_path) %>
    <div class="hidden absolute inset-auto right-0 mr-6 mt-0 py-4 bg-white rounded-xl min-w-[200px] shadow-context" data-toggle-panel-target="panel">
      <%= button_to t('avo.sign_out'), main_app.send(:destroy_user_session_path), method: :delete, form: { "data-turbo" => "false" }, class: "appearance-none bg-white text-left cursor-pointer text-green-600 font-semibold hover:text-white hover:bg-green-500 block px-4 py-1 w-full" %>
    </div>
  <% end %>
</div>
<!-- After -->
<% destroy_user_session_path = "destroy_#{Avo.configuration.current_user_resource_name}_session_path".to_sym %>

<div <% if main_app.respond_to?(destroy_user_session_path) %> data-controller="toggle-panel" <% end %>>
  <a href="javascript:void(0);" class="flex items-center cursor-pointer font-semibold text-gray-700" data-action="click->toggle-panel#togglePanel">
    <% if _current_user.respond_to?(:avatar) &&  _current_user.avatar.present? %>
      <%= image_tag _current_user.avatar, class: "h-12 rounded-full border-4 border-white mr-1" %>
    <% end %>
    <% if _current_user.respond_to?(:name) && _current_user.name.present? %>
      <%= _current_user.name %>
    <% elsif _current_user.respond_to?(:email) && _current_user.email.present? %>
      <%= _current_user.email %>
    <% else %>
      Avo user
    <% end %>
    <% if main_app.respond_to?(destroy_user_session_path) %>
      <%= svg 'chevron-down', class: "ml-1 h-4" %>
    <% end %>
  </a>

  <% if main_app.respond_to?(destroy_user_session_path) %>
    <div class="hidden absolute inset-auto right-0 mr-6 mt-0 py-4 bg-white rounded-xl min-w-[200px] shadow-context" data-toggle-panel-target="panel">
      <!-- Add this 👇 -->
      <% classes = "appearance-none bg-white text-left cursor-pointer text-green-600 font-semibold hover:text-white hover:bg-green-500 block px-4 py-1 w-full" %>

      <% if I18n.locale == :en %>
        <%= link_to "Switch to Portuguese", { set_locale: 'pt-BR' }, class: classes %>
      <% else %>
        <%= link_to "Switch to English", { set_locale: 'en' }, class: classes %>
      <% end %>
      <!-- Add this 👆 -->

      <%= button_to t('avo.sign_out'), main_app.send(:destroy_user_session_path), method: :delete, form: { "data-turbo" => "false" }, class: classes %>
    </div>
  <% end %>
</div>

Feel free to customize the dropdown as much as you need it to and add as many locales as you need.

After v 2.3.0

Use the profile_menu to add the language switching links.

# config/initializers/avo.rb
Avo.configure do |config|
  config.profile_menu = -> {
    link "Switch to Portuguese", path: "?set_locale=pt-BR"
    link "Switch to English", path: "?set_locale=en"
  }
end

# Workflow

You will now be able to edit the attributed you marked as translatable (eg: name) in the locale you are in (default is en). Next you can go to the navbar on the top and switch to a new locale. The switch will then allow you to edit the record in that locale, and so on.

# Support

This is the first iteration of multilingual content. It's obvious that this could be done in a better way and we'll add that better way in the future, but until then you can use this method to edit your multilingual content.

Thanks!
