我正在将我的 Ruby on Rails 应用程序安装到实时服务器上，但必须从版本 3 降级到 2，因为这是我的共享托管服务提供商所支持的全部。我能够毫无问题地调整我的模型、控制器和路线。我遇到的问题是视图渲染。
我按照 Rails 2 的要求完成了为每个控制器创建默认布局的过程。当我在服务器上运行应用程序时，它启动得很好，并且烟幕 index.html 是可见的，但是如果我删除它并尝试查看真正的应用程序，我得到的只是损坏的链接和无法加载的文件浏览器。
我确信这是由于降级造成的问题。关于我做错了什么的任何想法？
Doing a downgrade from Rails 3 to Rails 2 seems to me like a crazy thing to do for many reasons:
1) Rails 4 is already released. You should be looking to upgrade instead of downgrading.
2) There are many hosts out there that offer amazing services and even some free. Heroku is a great place to start if you don't want to manage your own server.
3) Rails 3 was almost a complete rewrite of the way Rails worked. This includes the addition of the Assets Pipeline which is a blessing in terms of development.
With that said, if you're still looking to downgrade, I would try to revert the steps found in many Upgrading Rails 2 to Rails 3 tutorials out there.
They are a bit long and many steps required to put here but a simple google search will yield many great resources. Here's a Railscasts http://railscasts.com/episodes/226-upgrading-to-rails-3-part-2
