推荐答案
本质上，资源路由是指资源赋予控制器动作能力.
In essence, routing resources is when resources gives action abilities to a controller.
http://guides.rubyonrails.org/routing.html#specifying-a-controller-to-use
如果使用多元化资源作为处理任何项目的通用请求的一种方式，那么单一资源就是处理手头当前项目的一种方式.
If a pluralized resources is used as a way to handle generic requests on any item, then a singular resource is a way to work on the current item at hand.
换句话说，如果我有一个苹果集合，要检索一个特定的苹果，我必须通过发送苹果的 ID 来告诉路由器苹果"要检索什么苹果.如果我已经有一个 Apple，则不需要 ID.
So in other words, if I have a collection of Apples, to retrieve a specific apple, I'd have to tell the router "Apples" what apple to retrieve by sending the ID of the apple. If I already have one Apple, then an ID is not needed.
通过查看它们具有的操作(或路线)来注意两者之间的差异:
Notice the differences between the two by looking at what actions (or routes) they have:
- 资源:索引、新建、创建、显示、编辑、更新、销毁
- 资源:新建、创建、显示、编辑、更新、销毁
- resources: Index, new, create, show, edit, update, destroy
- resource: new, create, show, edit, update, destroy
在你的例子中:
- 控制器地理编码器"是一个单一的资源，可用于编辑、创建、更新等.
- 控制器帖子"是一种复数资源，用于处理传入的通用帖子，您可以对其进行索引、编辑、创建等操作
