反向导轨路由：从URL查找动作名称

本文介绍了反向导轨路由：从URL查找动作名称的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我了解如何转换：controller ，：action， ：etc 转换为网址。我正在寻找相反的方向，如何从URL中找到Rails路由器将调用的操作？解决方案其他人可能有更短的方法来执行此操作，但是如果您只是在评估URL，则转到 ActionController :: Routing :: RouteSet 类 用于 config.routes.rb map.resources：sessions 要查找的代码是： ActionController :: Routing :: Routes.recognize_path（'/ sessions / new'，{：method =>：get}） ＃=> {：controller => 会话，：action => 'new'} 右： ActionController :: Routing :: Routes.recognize_path（'/ sessions / 1 / edit'，{：method =>：get}）＃=> {：controller => 会话，：action => ‘edit’，：id => 1} 错误-没有方法明确添加，它将默认匹配 /：controller /：action /：id ： ActionController :: Routing :: Routes.recognize_path（'/ sessions / 1 / edit'）＃=> {：controller => 会话，：action => ‘1’，：id => 'edit'} 如果您愿意采取行动，并且想知道，那就有点通过调用 params [：action] 更容易，您可以在此处找到有关路由集的所有信息： http://caboo.se/doc//classes/ActionController/Routing/ RouteSet.html＃M004878 希望这会有所帮助！ I understand how to turn :controller, :action, :etc into a URL. I'm looking to do the reverse, how can the action that the rails router will call be found from the URL? 解决方案 someone else might have a shorter way to do this, but if you are just evaluating a URL, then you go to the ActionController::Routing::RouteSet classfor a config.routes.rbmap.resources :sessionsthe code to find is:ActionController::Routing::Routes.recognize_path('/sessions/new', {:method => :get})#=> {:controller => 'sessions', :action => 'new'}Right:ActionController::Routing::Routes.recognize_path('/sessions/1/edit', {:method => :get})#=> {:controller => 'sessions', :action => 'edit', :id => 1}Wrong - without the method being explicitly added, it will default match to /:controller/:action/:id:ActionController::Routing::Routes.recognize_path('/sessions/1/edit')#=> {:controller => 'sessions', :action => '1', :id => 'edit'}If you are within the action and would like to know, it is quite a bit easier by calling params[:action]everything you ever wanted to know about routeset can be found here: http://caboo.se/doc//classes/ActionController/Routing/RouteSet.html#M004878Hope this helps! 这篇关于反向导轨路由：从URL查找动作名称的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
