Ruby on Rails：路由树的地方层次结构 [英] Ruby on Rails: Routing for a tree hierarchy of places

问题描述

因此，我们有一个遗留系统，该系统可以跟踪ID为欧洲/法国/巴黎的地方，而我正在构建一个Rails外观以将其转换为类似http：// foobar / places / Europe / France的URL /巴黎。这项要求是不可商议的，可能的级别数是无限的，并且我们不能逃脱斜线。

So we've got a legacy system that tracks places with IDs like "Europe/France/Paris", and I'm building a Rails facade to turn this into URLs like http:// foobar/places/Europe/France/Paris. This requirement is not negotiable, the number of possible levels in unlimited, and we can't escape the slashes.

为 http：// foobar / places / Europe 很简单：

map.resources :places

...但是http：// foobar /地方/欧洲/法国抱怨欧洲没有任何反应。我尝试过：

...but http:// foobar/places/Europe/France complains "No action responded to Europe". I tried:

map.connect '/places/:id', :controller => 'places', :action => 'show' 

...但是这给出了相同的结果，因为：id显然在第一个'/'。如何使ID覆盖位置之后的所有内容？

...but this gives the same result, as apparently the :id ends at the first '/'. How do I make the ID cover anything and everything after the "places"?

推荐答案

请参阅《路由指南》以获取完整信息。文档：

Have a look at the Routing Guide for full documentation:

http：//guides.rubyonrails。 org / routing.html

具体是 4.9 Route Globbing部分。

Specifically section "4.9 Route Globbing".

但我认为您真正想要做的就是声明您的路线，例如：

But I think what you really want to do is declare your route like:

map.connect '/places/*id', :controller => 'places', :action => 'index'

以类似URL的

/places/foo/bar/1

Yields a params[:id] => ["foo", "bar", "1"]

您可以轻松地（重新）加入用 /产生想要的完整字符串 foo / bar / 1（您可能必须手动重新插入前导斜杠。

Which you could easily (re)join with "/" to yield the full string you want "foo/bar/1" (you will probably have to re-insert the leading slash manually.

应该可以你去。
