Rails3 +不显眼的 JavaScript +移动 - 有人让它工作吗？

我有一个简单的 Rails 项目，它使用不显眼的 Javavscript 进行 ajax 链接/表单处理。一切在桌面上都运行良好。

现在，我正在尝试使该网站移动化。我的理解是，这涉及以下步骤：

启用ApplicationController将request.format更改为：mobile。通常这是通过一个过滤器来完成的，该过滤器读取传入的请求属性并可能设置 request.format = :mobile:
```
before_filter：调整_format_for_mobile
```

向 mime_types.rb 添加一些行：

Mime::Type.register_alias "text/html", :mobile
Mime::Type.register_alias "text/javascript", :mobilejs

向 format.mobilerespond_to 块添加一些新行和 format.mobilejs

respond_to do |格式|
  格式.js 
  格式.mobilejs
  format.html {redirect_to @post }
  format.json { 渲染 json: @post }
结尾

我已尝试过以各种方式完成所有这些。我尝试在控制器内“手动”执行#1，然后尝试了 mobile-fu。我在#2 中尝试了各种东西，比如“application/javascript”。我还尝试了执行 #3 的各种方法（例如显式渲染）。

我可以让应用程序执行除处理来自移动浏览器的 ajax 调用之外的所有操作。它要么找不到合适的模板，要么将模板呈现为 text/html 而不是 Javascript。

我已经了解了用于移动检测的 Railscast (#199)，以及这里的一些问题/答案（可能看起来有点过时）。我无法让这个工作。

所以我的问题是：有人能够做到这一点吗？如果可以的话，你能提供一个简单的1、2、3来说明如何做到这一点吗？我认为问题在于文档在不引人注目的 javascript + 移动问题上很薄弱，并且过去有效的各种东西在 Rails 3 中不再有效（也许）？在这一点上，我愿意做几乎任何事情（例如主要的重新配置）来使其正常工作。如果需要的话，我什至愿意放弃不引人注目的 JavaScript 位并以“非轨道”方式做事。

谢谢

I have a simple rails project which makes use of unobtrusive Javavscript for ajax link/form processing. Everything works great on the desktop.

Now, I'm trying to make the site mobile. My understanding is that this involves the following steps:

Enabling the ApplicationController to change the request.format to :mobile. Normally this is done with a filter which reads the incoming request properties and maybe sets request.format = :mobile:
```
before_filter :adjust_format_for_mobile
```

Adding some lines to mime_types.rb:

Mime::Type.register_alias "text/html", :mobile
Mime::Type.register_alias "text/javascript", :mobilejs

Adding some new lines to the respond_to blocks for format.mobile, and format.mobilejs

respond_to do |format|
  format.js 
  format.mobilejs
  format.html { redirect_to @post }
  format.json { render json: @post }
end

I've tried to do all of these in various ways. I tried doing #1 "by hand" inside the controller, then tried mobile-fu. I tried various things in #2 like "application/javascript". I also tried various ways of doing #3 (e.g. explicit render).

I can get the application to do everything except process an ajax call from a mobile browser. It will either not find the appropriate template, or render the template as text/html rather than Javascript.

I've been through the Railscast for mobile detection (#199), as well as a number of questions/answers here (which seem a little outdated maybe). I can't get this working.

So my question: has anyone been able to make this work? If so can you offer a simple 1,2,3 for how to do it? I think the problem is that the documentation is thin on the unobtrusive javascript + mobile issue, and various things that have worked in the past are no longer working in rails 3 (maybe)? At this point I'm willing to do almost anything (e.g. major reconfiguring) to get this working. I'm even willing to dump the unobtrusive javascript bit and do things in a "non-rails" way if I need to.

Thanks
