module Decidim
# 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 %>
#
module LocalizedLocalesHelper
# Converts a given array of strings to an array of Objects representing
# locales.
#
# collection - an Array of Strings. By default it uses all the available
# locales in Decidim, but you can pass another collection of locales (for
# example, the available locales for an organization)
def localized_locales(collection = Decidim.available_locales)
klass = Class.new do
def initialize(locale)
@locale = locale
end
def id
@locale.to_s
end
def name
I18n.with_locale(@locale) { I18n.t("name", scope: "locale") }

end
