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

require 'rubygems'
require 'zip/zip'

def unzip_file (file, destination)
  Zip::ZipFile.open(file) { |zip_file|
   zip_file.each { |f|
     f_path=File.join(destination, f.name)
     FileUtils.mkdir_p(File.dirname(f_path))
     zip_file.extract(f, f_path) unless File.exist?(f_path)
   }

#Behold, the nav_link:

The nav_link helper works just like the standard Rails link_to helper, but adds a 'selected' class to your link (or its wrapper) if certain criteria are met. By default, if the link's destination url is the same url as the url of the current page, a default class of 'selected' is added to the link.

For full usage details, see: http://viget.com/extend/rails-selected-nav-link-helper

Drop nav_link_helper.rb into app/helpers in your Rails 3.x app and enjoy.
