嵌套资源命名空间控制器

Question

我构建了一个没有命名空间的应用，现在想尝试学习命名空间。 以分离应用 api 和后端为例

试图得到这个结果 /backend/directorycategory/1/directorylisting

我已经删除了某些地方的 backend_ 以尝试调试，因为我怀疑它与目录列表是嵌套的并且没有像目录类别一样的后端这样的事实有关。

（如果您可以运行“rake routes”并发布输出，那可能会有所帮助）

您是否尝试在您的 routes.rb 中添加模块？我认为这可能接近您正在寻找的结果...

        resources :directorycategories, module: "backend" do
            resources :directorylistings
        end

或者你可以直接指定路径...

resources :directorycategories, path: "/backend/directorycategories" do
            resources :directorylistings
        end

我对 Rails 还很陌生，所以我不是 100%，但我不知道您的控制器是否需要所有这些额外的代码。 （您的控制器文件结构可能更清楚地说明您正在尝试做什么）

希望这会有所帮助。 :)
