如何制作可插拔的 Rails 应用程序
基本上，我想编写一个
- 可嵌入其他 Rails 3 应用程序（基本上是一些路线、控制器和一些视图，没有持久模型）的
- Rails 3 应用程序，可以独立工作
- ，可以捆绑到 gem 中并从命令启动（这个更值得拥有）
根据我所读到的，轨道引擎将完全解决我的问题。当你用谷歌搜索时，你得到的绝大多数内容要么是人们抱怨缺乏文档，要么是有人构建了一个插件，而不是真正的可插入应用程序。谁能给我指出更好的文档/截屏视频（如果需要的话甚至是书籍）
非常感谢
Basically, I would like to write a rails 3 app that
- is embeddable in other rails 3 apps (basically some routes, a controller, and some views, no persisting models)
- works standalone
- can be bundled up into a gem and be launched from a command (this one is more a nice to have)
From what I have read, rails engines would totally solve my problem. The vast majority of what you get when you google it is either people complaining about a lack of documentation, or someone building a plugin, not really a pluggable app. Could anyone point me to better documentation/screencasts (even books if nessicary)
Thanks a bunch

马特，我正在开发一个 Rails 论坛引擎，我必须解决很多问题，因此我将基础知识提取到一个涵盖许多常见需求的详细示例中。它是通用的，因此您可以轻松地适应它。我还没有详细的文档，但我链接到我用来解决这个问题的来源，并且我很乐意回答有关我的来源的问题。看看：

Matt, I'm working on a rails forum engine and I had to figure a lot of this out so I extracted the foundation into a detailed example that covers a lot of common needs. It's generalized so you can easily adapt it. I don't have detailed documentation yet but I link to the sources that I used to figure this out, and I'm happy to answer questions about my source. Check it out:

引擎确实是您所需要的，并且完全是为了满足您的要求而设计的。
实际上，Rails3 中的引擎工作得更好。
Rails 以前版本中的很多抱怨都在最新版本中得到了解决。我在 Rails 2.x 中广泛使用了引擎，说实话并没有发现它们有那么糟糕。
An Engine is really what you need and totally designed to meet your reuirements.
Engines actually work a lot better in Rails3.
A lot of the complaints from previous versions of Rails have been resolved in the latest version. I have used engines quite extensively in Rails 2.x and not found them to be all that bad to be honest.
