Я не знаю точно, что является причиной, но мое мнение таково:
UsersController в методе _default_wrap_model пытается получить доступ получить к модели Profile (без имен) и поднимайтесь ошибкой. Потому что, когда я переименовываю модель Profile (пример: Info), у меня нет ошибок, и все в порядке.
Так что мой вопрос: как избежать этой ошибки?
