Multi-language URLs

Implementing multi-language URLs is a common use-case. Using a route scope block in Avo allows you to seamlessly adapt your application to support multiple languages, enhancing the user experience. This recipe will guide you through the steps to configure a locale scope, ensuring your application dynamically sets and respects the user's preferred language. Let's dive in!

1. Mount Avo within a :locale scope

Using a locale scope is an effective way to set the locale for your users.

# config/routes.rb
Rails.application.routes.draw do
  scope ":locale" do
    mount_avo
  end
end

2. Apply the locale Scope

To properly handle localization within Avo, you'll need to ensure the locale parameter is respected throughout the request which we'll do by overriding the set_avo_locale method in your Avo::ApplicationController as follows:

INFO

If you don't have the app/controllers/avo/application_controller.rb file present in your app, you can eject it using this command:

rails generate avo:eject --controller application_controller

# app/controllers/avo/application_controller.rb
module Avo
  class ApplicationController < BaseApplicationController
    def set_avo_locale(&action)
      I18n.with_locale(params[:locale], &action)
    end
  end
end

This implementation uses I18n.with_locale to set the desired locale for the duration of the request, ensuring consistent localization behavior across Avo's interface and that it won't impact the other non-Avo parts of your app.
