Devise/Rails - 未定義的方法`許可'

問題：我正在嘗試創建一個自定義操作，允許教師通過「批准」操作批准學生。批准操作獲取相應的行並將狀態從「掛起」更改爲「活動」並保存該記錄。目前，當我點擊鏈接，更好的錯誤給了我2Devise/Rails - 未定義的方法`許可'

「爲未定義的方法'許可證」‘’：字符串」

它提到一些關於

設計:: ParameterSanitizer＃許可證

請記住，我對Devise很新，很難過！

控制器

class Teachers::RegistrationsController < Devise::RegistrationsController 

    # APPROVE 
     def approve 
     @ts = TeacherStudent.find_by(teacher_id: params[:teacher], student_id: params[:student]) 
     @ts.status = "active" 
     @ts.save 
     redirect_to teachers_path 
     end 

end

查看

= link_to "Approve", approve_path(teacher: s.teacher_id, student: s.student_id), method: :put

的routes.rb

put 'teachers' => 'teachers#approve', as: :approve

錯誤

我們需要看到您的設計registrations_controller.rb底部添加以下代碼。特別是底部應該有一些強大的參數方法。 – MarsAtomic

嗯，我是在假設上面發佈的是設計註冊控制器，如果是這樣的話，那就是那裏的一切。 –

請發佈完整的錯誤堆棧跟蹤。 – Pavan

問題很可能在您的權限中。

您是否使用強參數？如果是這樣，你需要允許那裏的領域。

例子：

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

在你的老師控制器 -

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
