会员路线困难答案

【问题标题】：difficulty with member routes会员路线困难

【问题描述】：

更新：这完全是一个可怕的错误——我更新了错误的路由文件！这确实有效：get 'users/:id/groups/' => 'users#groups'

我希望能够查看属于特定用户的组，但在设置可解析为的路由时遇到问题：

/users/:id/groups

出于某种原因。我猜想设计可能会妨碍您。

我尝试了以下方法：

resources :users 

match '/users/:id/groups', to: 'users#groups', via: :get

和

resources :users do
  member do
    get 'groups'
  end
end

当我打电话给rake routes时，这样的路线永远不会出现：

【问题讨论】：

你能发布你的整个 routes.rb 吗？这些都应该工作......
是的 - 对不起，我忘了提到我正在使用设计。（更新后）
优先级似乎没有影响
使用 devise 可以防止您嵌套传统意义上的资源。查看此问题以获取更多信息和可能的解决方案：stackoverflow.com/questions/17349666/…
啊，你用的是设计……

标签： ruby-on-rails devise routes ruby-on-rails-4

【解决方案1】：

为什么在尝试嵌套资源时要指定成员？你试过了吗

resources :users do
  resources :groups, only: :index
end

【讨论】：

但这会将/users/:id/groups 路由到groups#index。我希望它路由到users#my_groups。还是我弄错了。我想我不清楚嵌套资源和成员之间的区别。
另外 - 这样做不会在我的 rake routes 通话中显示新路线。
啊，好吧，所以您尝试获取 my_groups 页面而不是嵌套组资源。哦，顺便说一句，我相信'match'在rails 4中已被弃用。你需要像“get'/users/:id/groups'，to：'users#groups'”一样 - 见guides.rubyonrails.org/routing.html
或“get 'users/:id/groups/ => 'users#groups'”
