**WARNING: Can't mass-assign protected attributes for SimpleCaptcha::SimpleCaptchaData: key**

Answer 1

看看你的电话，<%= show_simple_captcha(:label => "", :placeholder => "", :code_type => "numeric") %>你似乎正在使用基于控制器的 simple_captcha 实现

我没有看到您的ApplicationController代码，但请确保以下行存在于app/controllers/application.rb

ApplicationController < ActionController::Base
  include SimpleCaptcha::ControllerHelpers
end

更新模型的示例：

class User < ActiveRecord::Base
  apply_simple_captcha
end

class User < ActiveRecord::Base
  apply_simple_captcha :message => "The secret Image and code were different", :add_to_base => true
end
