Module: Decidim::LocalizedLocalesHelper

Defined in:
app/helpers/decidim/localized_locales_helper.rb

Overview

A helper that converts an array of locale IDs (two-letter identifiers, e.g. ‘“en”`) to an array of Objects that have both the ID and their name in their own language (e.g., `“English”`).

This is intended to be used in forms, when selecting the default locale form a given list, or when creating a list of radio buttons, for example.

Examples:

<%= form.collection_select :default_locale, localized_locales(current_organization.available_locales), :id, :name %>

<% localized_locales(current_organization.available_locales).each do |locale| %>
  <p><%= locale.name %></p>
<% end %>
