Rails 4-资源ID路由的显式模型名称 [英] Rails 4 - explicit model name for resource id route

问题描述

在 routes.rb 中定义以下路由时：

resources :streams

Rails生成以下网址：

Rails generates the following urls:

        streams    GET    /streams(.:format)
                   POST   /streams(.:format)
        new_stream GET    /streams/new(.:format)
       edit_stream GET    /streams/:id/edit(.:format)
            stream GET    /streams/:id(.:format)
                   PATCH  /streams/:id(.:format)
                   PUT    /streams/:id(.:format)
                   DELETE /streams/:id(.:format)

我想有一个明确的资源ID，即：stream_id 而不是：id 。

I would like to have an explicit resource id, i.e. :stream_id instead of :id.

编辑：

对于简单资源，解决方案类似于@ user2262149和@ vimsha提​​到了：

For simple resources the solution is like @user2262149 and @vimsha mentioned:

resources :streams, :param => :stream_id

问题出在嵌套资源上。如果我这样做：

The problem is with nested resources. If I do this:

resources :streams do
  resource :comment, :param => :comment_id
end

我会得到这条路线（没关系）：

I will get this route (which is ok):

stream_comments   GET  streams/:stream_id/comments(.:format)

，但另一方面是父资源（同样，：id 而不是：stream_id ）：

but on the other hand for the parent resource (again, :id instead of :stream_id):

streams   GET  streams/:id(.:format)

所以...。

如果我尝试解决它，请添加：param => ：stream_id 到父资源：

So....
If I try to solve it adding :param => :stream_id to the parent resource:

resources :streams, :param => :stream_id do
  resource :comment, :param => :comment_id
end

然后为父资源确定路由：

Then for the parent resource the route is ok:

stream GET    /api/streams/:stream_id(.:format)

但是我对子资源真是一团糟：

but I get a real mess for the child resource:

stream_comments GET    /api/streams/:stream_stream_id/comments(.:format)

您是否知道如何解决这个问题？

Do you have an idea how to solve this problem??

推荐答案

我不确定这是否是您要查找的内容，但是在您的 routes.rb ，

I'm not sure if this is what you are looking for but, in your routes.rb,

如果您使用

resources :streams, param: :stream_id

Rails将生成以下URL：

Rails will generate the following urls:

          streams GET      /streams(.:format)                       streams#index
                  POST     /streams(.:format)                       streams#create
       new_stream GET      /streams/new(.:format)                   streams#new
      edit_stream GET      /streams/:stream_id/edit(.:format)       streams#edit
           stream GET      /streams/:stream_id(.:format)            streams#show
                  PATCH    /streams/:stream_id(.:format)            streams#update
                  PUT      /streams/:stream_id(.:format)            streams#update
                  DELETE   /streams/:stream_id(.:format)            streams#destroy

希望这会有所帮助

更新：

我不确定这是否是最佳做法，或者是否有更好的方法，但是如果您尝试尝试怎么做：

I'm not sure if this is best practices or not or if there is a better way but what if you try:

resources :streams, param: :stream_id

resources :streams, only: [] do
  resource :comment, param: :comment_id
end

轨道会生成以下网址：

            streams GET      /streams(.:format)                         streams#index
                    POST     /streams(.:format)                         streams#create
         new_stream GET      /streams/new(.:format)                     streams#new
        edit_stream GET      /streams/:stream_id/edit(.:format)         streams#edit
             stream GET      /streams/:stream_id(.:format)              streams#show
                    PATCH    /streams/:stream_id(.:format)              streams#update
                    PUT      /streams/:stream_id(.:format)              streams#update
                    DELETE   /streams/:stream_id(.:format)              streams#destroy
     stream_comment POST     /streams/:stream_id/comment(.:format)      comments#create
 new_stream_comment GET      /streams/:stream_id/comment/new(.:format)  comments#new
edit_stream_comment GET      /streams/:stream_id/comment/edit(.:format) comments#edit
                    GET      /streams/:stream_id/comment(.:format)      comments#show
                    PATCH    /streams/:stream_id/comment(.:format)      comments#update
                    PUT      /streams/:stream_id/comment(.:format)      comments#update
                    DELETE   /streams/:stream_id/comment(.:format)      comments#destroy
