Devise/Rails - undefined method `permit '

Проблема: Я пытаюсь создать настраиваемое действие, которое позволяет учителю одобрить ученика посредством действия« одобрить ». Утверждающее действие выбирает соответствующую строку и изменяет статус с «ожидающего» на «активный» и сохраняет запись. В настоящее время, когда я нажимаю на ссылку, лучше ошибки дает мнеDevise/Rails - undefined method `permit '

"неопределенный метод` разрешение»для "2": String"

она упоминает что-то о

Разрабатывают :: ParameterSanitizer разрешение #

Пожалуйста, имейте в виду, я очень новичок в разработке и в тупике!

Мы должны видеть ваш DEViSE registrations_controller.rb. В частности, в нижней части должны присутствовать некоторые сильные параметрические методы. – MarsAtomic

Хм, я был в предположении, что то, что было опубликовано выше, было контроллером регистрации разработки, если это так, то есть все там. –

Пожалуйста, разместите свою полную стек стека ошибок. – Pavan

Проблема, скорее всего, в ваших разрешениях.

Вы используете сильные параметры? Если это так, вы должны разрешить поля там.

Пример:

def teacher_params 
    params.require(:teacher).permit(:email, :current_password, :password, :password_confirmation) 
end

Добавьте следующий код в нижней части вашего Учитель эксплуатации контроллеры

private 
def user_params 
    accessible = [:email, _____] # extend with your own params 
    accessible << [ :password, :password_confirmation ] unless params[:teacher][:password].blank? 
    params.require(:teacher).permit(accessible) 
end
