在Ruby on Rails中路由生成的路径

Question

我是ruby-on-rails的初学者,我花了最后一小时尝试做以下事情:

我有一个ruby-on-rails应用程序 - 包含帖子和类别的博客.我希望有另一个帖子的URL(我希望有http://localhost:3000/news而不是http://localhost:3000/posts)首先我试图将控制器和类替换Posts为News,但我放弃了(因为annoyng奇异复数的事情).然后在我的I替换map.resources :posts(案例1)

  map.resources :news, :controller => "posts"     #case 2

要么

  map.resources :posts, :as => 'news'             #case 3

在routes.rb我上看到的一些网站.它也不起作用.

我怎样才能做到这一点？

编辑:

输出rake routes是(只有第一行):

对于案例1和3:

               posts GET    /posts                           {:action=>"index", :controller=>"posts"}
     formatted_posts GET    /posts.:format                   {:action=>"index", :controller=>"posts"}
                     POST   /posts                           {:action=>"create", :controller=>"posts"}
                     POST   /posts.:format                   {:action=>"create", :controller=>"posts"}
            new_post GET    /posts/new                       {:action=>"new", :controller=>"posts"}
  formatted_new_post GET    /posts/new.:format               {:action=>"new", :controller=>"posts"}
           edit_post GET    /posts/:id/edit                  {:action=>"edit", :controller=>"posts"}
 formatted_edit_post GET    /posts/:id/edit.:format          {:action=>"edit", :controller=>"posts"}
                post GET    /posts/:id                       {:action=>"show", :controller=>"posts"}
      formatted_post GET    /posts/:id.:format               {:action=>"show", :controller=>"posts"}
                     PUT    /posts/:id                       {:action=>"update", :controller=>"posts"}
                     PUT    /posts/:id.:format               {:action=>"update", :controller=>"posts"}
                     DELETE /posts/:id                       {:action=>"destroy", :controller=>"posts"}
                     DELETE /posts/:id.:format               {:action=>"destroy", :controller=>"posts"}

案例2的输出:

           news_index GET    /news                            {:action=>"index", :controller=>"posts"}
 formatted_news_index GET    /news.:format                    {:action=>"index", :controller=>"posts"}
                      POST   /news                            {:action=>"create", :controller=>"posts"}
                      POST   /news.:format                    {:action=>"create", :controller=>"posts"}
             new_news GET    /news/new                        {:action=>"new", :controller=>"posts"}
   formatted_new_news GET    /news/new.:format                {:action=>"new", :controller=>"posts"}
            edit_news GET    /news/:id/edit                   {:action=>"edit", :controller=>"posts"}
  formatted_edit_news GET    /news/:id/edit.:format           {:action=>"edit", :controller=>"posts"}
                 news GET    /news/:id                        {:action=>"show", :controller=>"posts"}
       formatted_news GET    /news/:id.:format                {:action=>"show", :controller=>"posts"}
                      PUT    /news/:id                        {:action=>"update", :controller=>"posts"}
                      PUT    /news/:id.:format                {:action=>"update", :controller=>"posts"}
                      DELETE /news/:id                        {:action=>"destroy", :controller=>"posts"}
                      DELETE /news/:id.:format                {:action=>"destroy", :controller=>"posts"}

我在案例2中有错误,因为在我的源代码中我没有edit_news,例如<%= link_to 'Edit', edit_post_path(post) %>

Answer 1

"新闻"这个词在单数(成员)和复数(集合)名称之间存在歧义.你可以尝试解决这个问题,但你最终可能会让自己感到困惑,而且还会让你感到困惑.("news_path"应该是成员的id参数,还是收集路径？什么是"新闻"？)

让我们坚持称他们为帖子:

map.resources :posts, :as => "news", :singular => "news"

• 你的路线将是"/ news"
• 你的控制器将是PostsController
• 您的路径助手将是posts_path,post_path,edit_post_path等.

换句话说,在所有情况下,您都会将资源称为"帖子",但它们会显示在"/ news/*"下的路径中.
