Module: Spree::Admin::LocaleConcern

Extended by:: ActiveSupport::Concern

Included in:: BaseController, UserSessionsController

Defined in:: app/controllers/concerns/spree/admin/locale_concern.rb

Overview

Decouples the admin UI language from the store's content language.

I18n.locale drives the UI chrome (Spree.t labels) and follows the staff member's chosen admin language. Mobility.locale and Spree::Current.content_locale drive translated record fields (product/store names) and are pinned to the store's content locale — otherwise switching the admin to, say, Polish would make every Mobility-backed field fall back to nil for stores that don't translate their catalog into Polish.

Shared by Spree::Admin::BaseController and the Devise-based pre-auth controllers (UserSessionsController), which can't inherit admin behavior via the controller chain — hence a concern both include. Devise-based includers opt into the login-screen locale handling with before_action :set_login_locale.

ADMIN_LOCALE_COOKIE = Cookie storing the admin UI language chosen on the login screen, so a guest's pre-auth selection carries into the authenticated session. A signed-in user's saved selected_locale still takes precedence.
