ruby-on-rails-3 - Rails 简单的验证码属性

Question

当我在 Rails 3 项目 gem "simple-captcha"( https://github.com/galetahub/simple-captcha ) 中使用时，调用函数 <%= show_simple_captcha %> 时出现错误:

Can't mass-assign protected attributes: key

Answer 1

这对我有用:

将其放入初始化程序 (config/initializers/simple_captcha.rb)

Rails.configuration.to_prepare do
  class SimpleCaptcha::SimpleCaptchaData < ::ActiveRecord::Base
    attr_protected
  end
end
