Rails的路线不工作：模型

Question

在我的Rails应用程序3.1，我有一个模型命名为“孩子”

在我的routes.rb文件，我也行：

resources :children 

这里整个routes.rb中文字：

root :to => "pages#home" 

    resources :children 

以下是完整的耙路线的结果（注意，大多数航线都有相关ActiveAdmin）：

    children GET  /children(.:format)      {:action=>"index", :controller=>"children"} 
          POST  /children(.:format)      {:action=>"create", :controller=>"children"} 
       new_child GET  /children/new(.:format)     {:action=>"new", :controller=>"children"} 
       edit_child GET  /children/:id/edit(.:format)    {:action=>"edit", :controller=>"children"} 
        child GET  /children/:id(.:format)     {:action=>"show", :controller=>"children"} 
          PUT  /children/:id(.:format)     {:action=>"update", :controller=>"children"} 
          DELETE  /children/:id(.:format)     {:action=>"destroy", :controller=>"children"} 

当我运行 “耙路线：” 我看到这行的结果：

children GET /children(.:format) {:action=>"index", :controller=>"children"} 

这是我ChildrenController代码：

 def index 
     @children = Child.all 

     @base_class = "children-index" 
     @title = "Your Children" 

     respond_to do |format| 
      format.html # children/index.html.erb 
      format.json { render :json => @children } 
     end 
    end 

    def show 
     @child = Child.find(params[:id]) 

     @base_class = "child-show" 
     @title = child_name(@child) 

     respond_to do |format| 
      format.html # children/show.html.erb 
      format.json { render :json => @child } 
     end 
    end 

当我访问的URL“/儿童“我得到这个错误：

No route matches {:action=>"show", :controller=>"children"} 

下面是完整的跟踪：

为什么“/ children”试图执行“show”动作，以及为什么show动作像路由不在那里一样？我所有的其他模型都使用“resource：model”指令工作得很好。

Answer 1

在服务器输出我们有这个： Processing by ChildrenController#index as HTML 确认路线是正确的。

但在您的模板中，您正在使用服务器找不到的路线。

::的ActionView ::模板错误（没有路由匹配{：动作=> “秀”，：控制器=> “孩子”}）：

1: <h1><%= title %></h1> 
2: <ul> 
3: <%= @children.each do |child| %> 
4:  <li><%= link_to child.child_name(child), child_path(@child) %></li> 
5: <% end %> 
6: </ul> 

更确切地说，在第4行你有问题，大概在这里：child_path(@child)

你使用模型的任何自定义ID（覆盖to_param方法）？

只是要清楚，这不是一个路由错误，是一个模板错误
