I am experiencing a weird error that I no longer want to work around but understand.
When recently adding an english version of our homepage, I found that I can't generate the pathes as I do for the german locale:
2.3.0 :023 > I18n.available_locales
=> [:de, :en]
2.3.0 :019 > apps_path(locale: :de)
=> "/de/apps"
2.3.0 :020 > apps_path(locale: :en)
ActionController::UrlGenerationError: No route matches
{:action=>"apps", :controller=>"pages", :locale=>:en} missing required keys: [:locale]
As I said, I was able to work around that, by using either url_for or – when sticking with our example apps_en_path.
But I wanna know what causes this weird problem.
EDIT
A git bisect session helped me to find out that this happens since I added the route-translater gem to my project. Besides this issue it works fine for us.
I had this settings (in development.rb):
# RouteTranslator.config
config.force_locale = true
config.locale_param_key = :locale

end
I had a quick play through with your routes, and I had I similar issue with the de route. I think the apps_path route you're getting will only allow your default locale as param.
Adding the following option solved it for me:
RouteTranslator.config do |config|
config.generate_unlocalized_routes = true
end
This will generate the unlocalized routes correctly, so you can pass multiple locales to apps_path.
