ruby-on-rails – 为“ParameterSanitizer”设计NoMethodError’

我正在努力,一个错误,我每次尝试在我的网络上唱歌/

Heroku日志：

Started GET "/users/sign_in" for 201.235.89.150 at 2016-07-06 01:35:03 +0000
 Completed 500 Internal Server Error in 3ms (ActiveRecord: 0.0ms)
NoMethodError (undefined method `for' for #<Devise::ParameterSanitizer:0x007f5968e0a920>):
 app/controllers/application_controller.rb:11:in `configure_permitted_parameters'

application_controller.rb

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs,you may want to use :null_session instead.
  protect_from_forgery with: :exception

  before_filter :configure_permitted_parameters,if: :devise_controller?

    protected

        def configure_permitted_parameters
            devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username,:email,:password,:provider,:uid) }
            devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:username,:current_password) }
        end
end

事情是在当地工作正常.只是在Heroku.而且几天前它工作得很好.

解决方法

class ApplicationController < ActionController::Base    
  before_action :configure_permitted_parameters,if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up,keys: [:first_name,:last_name,:email])
    devise_parameter_sanitizer.permit(:account_update,:phone,bank_attributes: [:bank_name,:bank_account]])
  end
end

“.for方法在4.1中被弃用

第一个参数是动作名称. ：sign_up用于创建新的Devise资源(如用户),并且：account_update用于编辑/更新资源.

第二个参数：：keys包含一个你允许的参数的数组.

如果你想要nested_attributes,有一个例子：account_update,你把一个单独的数组放在一起,这个键是_attributes.
