rails_best_practices

rails_best_practices是一个自动检查违背最佳实践代码的Gem，它会根据ihower在Kungfu Rails大会上的Rails最佳实践的演讲内容，检查Rails应用程序文件的质量。它是一个静态代码解析工具。

 

rails_best_practices的安装和使用都非常方便，只需简单两条命令就能知道代码中何处需要修改：

 

sudo gem install rails_best_practices --source http://gemcutter.org
rails_best_practices .

 

最新的0.3.21版本中，rails_best_practices已经完成了大部分最佳实践，使用者可以自行配置要检测的内容，目前支持的最佳实践有：
