Github 喜欢 Rails 中的路由 [英] Github like routes in Rails

问题描述

在 rails 中使用类似链式路由的 github

我有类似的网址:

'localhost:3000/document_managers/[:module_name]'
'localhost:3000/document_managers/[:module_name]/1/2/3/.'  # can be any level deep

这是它们的路由定义:

map.connect '/document_managers/:module',
  :controller => "document_managers",
  :action => :new_tree,
  :module => ["A","B","C"]

map.connect '/docuemnt_managers/:module/*path',
  :controller => "document_managers",
  :action => "new_tree",
  :module => ["A","B","C"]

问题来了:

1. 除了从上面给出的数组，即("A","B","C") 就像在任何时候 URL 必须是类似

1. The idea that module name value can't be anything except from the given above array i.e("A","B","C") like at any time the URL must be something like

localhost:3000/document_managers/A/1 或

localhost:3000/document_managers/B/221/1 或

localhost:3000/document_managers/C/121/1

但事实并非如此localhost:3000/document_managers/D/121/1 被视为有效的 url即使D"不在列出的数组中，并且模块也被设置为 D上面

but that not the case even though localhost:3000/document_managers/D/121/1 is treated as valid url and module is set to D even though the "D" is not in listed array above

我想要 URL localhost:3000/document_managers/A如果额外参数不是，也重定向到相同的操作，即 new_tree在 URL 中提供的包含额外参数
localhost:3000/document_managers/C/121/1 然后重定向 URL适当地到所需的控制器和动作，但如果 URL 只有包含路径，直到模块名称 Rails 返回 routesActionController::UnknownAction 我不知道为什么，因为我已经定义了控制器和动作.

I want the the URL localhost:3000/document_managers/A to also redirect to same action i.e new_tree if the extra parameter isn't provided as in the URL contain extra parameters
localhost:3000/document_managers/C/121/1 then the URL is redirected appropriately to the desired controller and action but if the URL only contain the path until the module name the Rails return a routes ActionController::UnknownAction I don't know why as I have already defined the controller and action.

推荐答案

在 Rails 3.1 中，您可以在路由文件中执行此操作以获得您想要的:

In Rails 3.1, you can do this in your routes file to get what you want:

match '/document_managers/:module', 
  :controller => "document_managers",
  :action => :new_tree, 
  :constraints => {:module => /[ABC]/}
