Наконец-то я понял, как реализовать ежемесячную рассылку Stripes, используя этот учебник. http://railscasts.com/episodes/288-billing-with-stripe
До сих пор Пользователь может создавать и удалять свою подписку с помощью полосы.
Но как пользователь может изменить свою информацию о кредитной карте после создания подписки
Это мой код с комментариями и вопросами. Пожалуйста, помогите новым рельсам.:)
