用IP地址结束Rails 2 URL会导致路由错误？(Ending a Rails 2 URL with an IP address causes routing error?)

用IP地址结束Rails 2 URL会导致路由错误？(Ending a Rails 2 URL with an IP address causes routing error?)

我试图以http：// servername / find / by / CRITERION / VALUE的格式构造URL

CRITERION是一组有限的字符串，VALUE也是如此。 麻烦的是，VALUE在某些情况下需要成为IP地址，并且会导致路由错误。

这是我的路线：

map.find 'find/by/:criterion/:query', :controller => "find", :action => "by"

从Mongrel日志中的错误：

Processing ApplicationController#index (for 127.0.0.1 at 2010-05-07 10:20:32) [GET] ActionController::RoutingError (No route matches "/find/by/ip/1.2.3.4" with {:method=>:get}): Rendering rescues/layout (not_found)

如果我访问/ find / by / foo / bar或/ find / by / foo / 1234我没有问题。 我怀疑问题可能是Rails根据URL中的句点推断MIME类型，但我真的不知道如何禁用它。 我试过给路由传递一个：defaults => {：format =>：html}，但是导致Mongrel无法完全启动。

任何帮助感谢！

I'm trying to construct URLs in the format http://servername/find/by/CRITERION/VALUE

CRITERION is a finite set of strings, as is VALUE. Trouble is, VALUE needs to be an IP address in some situations, and it's causing me a routing error.

Here's my route:

map.find 'find/by/:criterion/:query', :controller => "find", :action => "by"

And the error, from the Mongrel logs:

Processing ApplicationController#index (for 127.0.0.1 at 2010-05-07 10:20:32) [GET] ActionController::RoutingError (No route matches "/find/by/ip/1.2.3.4" with {:method=>:get}): Rendering rescues/layout (not_found)

If I visit /find/by/foo/bar or /find/by/foo/1234 I don't have problems. I suspect the problem might be Rails' inference of MIME types based on periods in the URL, but I don't really know how I can disable that. I've tried passing a :defaults => {:format => :html} to the route but that causes Mongrel to fail to start entirely.

Any help appreciated!

路线通配工作！

我的路线是：

map.connect 'find/by/*query', :controller => "find", :action => "by"

这将每个数组对象之后的所有内容都放在Array，params [：query]之后。 对于查询/find/by/ip/1.2.3.4，这看起来像：

["ip", "1.2.3.4"]

所以我可以参考params [：query] [0]和params [：query] [1]。

如果有人有更好的办法，请发布！

Route globbing worked!

My route is now:

map.connect 'find/by/*query', :controller => "find", :action => "by"

This puts everything following /find/by/ into an Array, params[:query], one URL segment per array object. For the query /find/by/ip/1.2.3.4, this looks like:

["ip", "1.2.3.4"]

So I can just refer to params[:query][0] and params[:query][1].

If anyone has a better way of doing it, please post it!
