Question

所以我有ApplicationController.rb：

class ApplicationController < ActionController::Base
  protect_from_forgery

  def decode_email
    params[:email] = URI::decode(params[:email])
  end
end

然后是UsersController.rb：

class UsersController < ApplicationController
  before_filter :decode_email, only: [:show]

  def show
    #blah blah
  end
end

现在点击show动作会导致：

undefined local variable or method 'decode_email' for #<UsersController:0x007fb5f216a710>

为什么不继承该方法，以便它可以正确地用作before_filter？

Answer 1

class ApplicationController < ActionController::Base
  protect_from_forgery

  private
    def decode_email
      params[:email] = URI::decode(params[:email])
    end
end

正在为我工作

控制器不继承before_filter
