Я следовал Railscasts # 235 и # 236, чтобы настроить создание аутентификаций пользователей с помощью omniauth.http://railscasts.com/episodes/235-omniauth-part-1 http://railscasts.com/episodes/236-omniauth-part-2
У меня есть 2 логических атрибута в пользовательской модели: facebok_share и: twitter_share, которые я хочу установить в true при создании новой аутентификации.
У меня это работает, когда я создаю нового пользователя, но если существующий пользователь добавляет аутентификацию, я не могу получить логическое значение для обновления до true.
Когда вызывается apply_omniauth (omniauth), он устанавливает self.facebook_share = true или self.twitter_share = true в моей пользовательской модели.
Я попытался добавить новый метод apply_share, который изменяет логические значения в зависимости от провайдера, и я пытаюсь вызвать current_user.apply_share (omniauth), но в базе данных ничего не происходит.
Что я делаю не так?Спасибо!
