J'ai un certain nombre de paramètres régionaux disponibles I18n définis dans application.rbComment faire une boucle par toutes les variables I18n disponibles dans Rails 4
config/application.rb
...
config.i18n.available_locales = [:at, :de, :ch]
...
je dois manuellement expire le cache pour toutes les langues à la fois dans certaines actions du contrôleur. Existe-t-il un moyen de parcourir toutes les langues?
Ce n'était pas si difficile à la fin, j'ai mal orthographié la méthode que je pensais que ce doit être et donc une erreur à chaque fois. Si vous faites face au même problème jetez un oeil sur I18n.methods dans la console Rails.
Pour répondre à la question:

=> [:at, :de, :ch]
Alors available_locales est ce que je (et peut-être vous) requiers.
