Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

    @device = find_device
    interface = @device.interfaces.first
    @endpoint = interface.endpoints.first
    @logger = Logger.new("/var/log/monitor_usb.log")

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

SSL 设计目标:

1. 防内容篡改
2. 防冒充服务器身份
3. 加密通信内容

而翻墙的目标:

1. 不被检测出客户端在访问什么网站
2. 不被检测出服务器在提供翻墙服务
