Rails的路线错误的故障排除

我发现了一个奇怪的错误，当我尝试当我运行耙路线链接到show_members行动Rails的路线错误的故障排除

Routing Error 
No route matches "/groups/1/show_members" 

#routes.rb 
get 'groups/:id/members' => 'groups#show_members' 

#groups_controller.rb 
def show_members

我得到这个：

#rake routes 
      groups GET /groups(.:format)   {:controller=>"groups", :action=>"index"} 
      groups POST /groups(.:format)   {:controller=>"groups", :action=>"create"} 
     new_group GET /groups/new(.:format)  {:controller=>"groups", :action=>"new"} 
     edit_group GET /groups/:id/edit(.:format) {:controller=>"groups", :action=>"edit"} 
      group GET /groups/:id(.:format)  {:controller=>"groups", :action=>"show"} 
      group PUT /groups/:id(.:format)  {:controller=>"groups", :action=>"update"} 
      group DELETE /groups/:id(.:format)  {:controller=>"groups", :action=>"destroy"} 
     group_join GET /groups/join(.:format)  {:controller=>"groups", :action=>"join"} 
group_remove_user PUT /groups/remove_user(.:format){:controller=>"groups", :action=>"remove_user"} 
        GET /groups/:id/members(.:format){:controller=>"groups", :action=>"show_members"}

UPDATE：但我希望show_members动作要做的就是显示该组中的所有用户。我希望用户功能和路径保持不变。现在，show_members动作路由到组，与show相同。在我的组控制器中，我将默认显示组操作分为三个页面，一个显示组配置文件，一个显示show_members组中的成员，另一个显示新闻页面，当显示新闻时将显示show_news我明白了。

#groups_controller.rb 
def show_members 
    @group = Group.find(params[:id]) 
    @members = @group.users 
    @group_admin = User.find(@group.group_admin) 
    respond_to do |format| 
    format.html # show.html.erb 
    format.xml { render :xml => @group } 
    end 
end 

#rake routes 
group_join GET /groups/:group_id/join(.:format) {:controller=>"groups", :action=>"join"} 
group_remove_user PUT /groups/:group_id/remove_user(.:format) {:controller=>"groups", :action=>"remove_user"} 
group GET /groups/:group_id/:id/members(.:format) {:controller=>"groups", :action=>"show_members"} 
group_users GET /groups/:group_id/users(.:format) {:controller=>"users", :action=>"index"} 
group_user GET /groups/:group_id/users/:id(.:format) {:controller=>"users", :action=>"show"}

尼克的答案是正确的它修复您的问题，但你采取的做法不好，你应该有不同的模型，视图和合作为团体和用户提供消息。观看这个railscast http://railscasts.com/episodes/139。尽管您正在使用的导轨2和导轨3之间的路由语法已更改，但其他所有内容都是相同的。 – mark 2011-03-26 14:49:44

Rails是正确的，当它说，没有路由匹配/groups/1/show_members - 你routes.rb创造这样的事情/groups/1/members路线（不带“show_”）

你需要改变routes.rb到看起来像：

get 'groups/:id/show_members` => 'groups#show_members'

真棒。我完全这样做，我总是尽量不要。谢谢！ – illogikal 2011-03-26 14:38:49

那么这个问题当然是你没有做一切正确。

resources :groups do |group| 
    group.resources :members 
end 

link_to @member.name, [@group, @member]

魔法。

现在阅读指南将是一个非常好的主意。
