How to modify a gem files in rails 3 project

Question

我正在使用带有捆绑器的Rails 3，我使用捆绑器安装了gem，现在我需要通过修改gem的控制器来稍微修改gem的流程，我应该怎么做，我确定有一个命令在本地安装文件，以便我可以对其进行修改，我试图通过创建另一个具有相同名称的控制器来覆盖控制器，但听起来不起作用。

Answer 1

将其分叉在github上，进行更改，然后将您的gemfile指向分叉的仓库，如下所示：

gem "contact-us", :git => "git://github.com/eqbal/contact-us.git"

Answer 2

You should just be able to make a controller, inherit from the gem controller and override the method behavior as you see fit

class MyController < ContactUs::ContactsController
  def create
    # my code that changes the behavior
  end
end

And then you may have to tell your routes to go to your controller

resources :contacts,
  :controller => 'my_controller'
