私はDeviseのセットアップについてあまり知りませんが、Railsルーティングの国際化について少し時間をかけて調べました。答えに近づくための参照 (内容は主に、i18n Railscast のコメントに書いたコメントの再ハッシュであり、Rails i18n ルーティング情報の良いソースでもあります):
application_controller.rbは問題ないように見えますが、routes.rb を次のように変更してみてください。
config/routes.rb (例)
MyApp::Application.routes.draw do
scope ":locale", locale: /#{I18n.available_locales.join("|")}/ do
# ...
match '/about', to: 'static_pages#about'
# handles /valid-locale
root to: 'static_pages#home', as: "locale_root"
# handles /valid-locale/fake-path
match '*path', to: redirect { |params, request| "/#{params[:locale]}" }
end
# handles /
root to: redirect("/#{I18n.default_locale}")
# handles /bad-locale|anything/valid-path
match '/*locale/*path', to: redirect("/#{I18n.default_locale}/%{path}")
# handles /anything|valid-path-but-no-locale
match '/*path', to: redirect("/#{I18n.default_locale}/%{path}")
end
が 2 つあるため、スコープroot_paths
内の名前を変更:locale
して、アプリとテストで競合が発生しないようにしました。次のように RSpec を使用してルートをテストしました。
仕様/ルーティング/ルーティング_spec.rb
require 'spec_helper'
describe "Routes" do

I18n.available_locales.each do |locale|

# This will then get caught by the "redirecting fake paths" condition

end
