What is the better way to handle locales?

[pil0u]

Hello,

I have been successfully using meta-tags to handle i18n in the sense that for a given page, my application controller knows the locale and displays it in the right language. So are my meta tags.

Here is a simple example of my PagesController:

class PagesController < ApplicationController
  def home
    set_meta_tags(
      title: _("Home"),
      description: _("This is my Home description."),
      image_src: request.base_url + ActionController::Base.helpers.image_path(_("og_image_en.png")),
      index: true,
      og: {
        type: "website",
        url: request.original_url,
        title: _("My website"),
        description: _("This is my Home description."),
        image: request.base_url + ActionController::Base.helpers.image_path(_("og_image_en.png"))
      }
    )
  end
end

My home page is routed via /, but also, I handle my locales via the URL this way: https://mydomain.com/fr. Here is how my router works:

Rails.application.routes.draw do
  scope "(/:locale)", locale: /#{I18n.available_locales.join('|')}/ do
    root to: "pages#home"
  end
end

• meta tags work well in all languages for https://mydomain.com/
• they don't work for https://mydomain.com/:locale, even if that is the same page

Any recommendation would help, thank you!
