@ywjno 你在 win 下 gem install kgio 试试，能安装@我

@Rei 还有你代码注释的引号怎么打的？我总是复制你的，```ruby 前面是不是引号？

@Rei 谢谢你中下水平的 Rails 程序员，问题已经解决了。

class Email < ActiveRecord::Base
  attr_accessible :to, :from, :mail
end

自己打补丁后报的错。

ar_mailer_rails3 是把要发的邮件，都存到数据库中。然后我执行一下就异步发出去了。 ActiveModel::MassAssignmentSecurity::Error: Can't mass-assign protected attributes: mail, to, from 不知道如何把这几个属性，添加到白名单去。我看别人的源码，也没在 mailers 里面做啥处理啊。

class UserMailer < ActionMailer::Base
  default from: "[email protected]"

  def test
    mail(:to => "[email protected]",:body => "Have a good day!", :subject => "test mail")  
  end

end

@raven 好的，去 stackoverflow 看看去。

@jonny @hooopo 你们的话让我蒙圈了，说话直白简单一点。我的观点是，不懂就要问，当然自己也要学习，交流一下提高的快。

活动一般有多少人参加呢？

@ywjno win 下面开发，rails 跑起来慢，你是新手所以没遇到不能用的 gem。我歧视两种人，一种是新手，一种是歧视新手的人。

主要是 win 下面开发，确实有很多的问题。首页除了热门帖子，也可以显示新手帖子。

这个:mail,:to,:from 是 mailers 里面的，不是 models 里面，不知道去哪里写？

高手，你为什么不解答下新手的问题，到瞎扯淡专区发言？

代码里应该如何写，才能行？不想 config.active_record.whitelist_attributes = false

活动组织了以后，最后在社区有一个总结。

谢谢华顺，那我不瞎折腾了。

恩，看到了，只是我下载的 ImageMagick 怎么没有 include 和 lib 目录？ 我下载的是 ImageMagick-6.7.6-9-Q16-windows-dll.exe

有木有个对比图？

自己回复下 读写权限：公共读权限

谁？

怎么解决这个问题？

大家水平菜，还没开始玩呢？只是注册下，具体怎么玩还不知道呢。

这个会不会太粗浅了？

是不是执行下 bundle exec rake assets:precompile 就可以？ 还是要修改很多配置？能不能简单说下要处理的地方。

昨天去下载下来，确实很大。第一次听华顺现场教学，很不错。羡慕他的本子

win 下开发，也可以，只是运行起来慢了点。不很爽罢了。

关键我觉得必须还得有用盛大云的人帮你反向代理才行，不仅仅是域名的问题。

华顺帮我代理了一下，确实可以用。
