为什么Ember Router只允许导航到叶子路由？

Question

我最近注意到Ember Router的一些东西是它只允许导航到叶子路径 - 没有子路由的路由.

现在,除非我做错了事,否则这似乎是设计中的错误/错误.

我们来举例如下:

我有一个项目集合,每个项目都有很多合作者,我想建立一个具有3列布局的UI(类似于您的标准桌面电子邮件客户端),在左边我有一个项目列表,当点击一个项目中间列显示协作者列表,单击协作者将其详细信息加载到右侧列.

现在有了路由,我想/projects/1在点击项目时导航到单击/projects/1/collaborators/23协作者时导航到.

这是一个说明嵌套路由的第一部分的路由器:

App.reopen(
  Router: Ember.Router.extend(
    enableLogging: true
    location: 'hash'

    root: Ember.Route.extend(
      index: Ember.Route.extend(
        route: '/'

        redirectsTo: 'projects'
      )

      projects: Ember.Route.extend(
        # This route is not routable because it is not a leaf route.
        route: '/projects'

        connectOutlets: (router) ->
          # List projects in left column
          router.get('applicationController').connectOutlet('projects', App.projects)

        show: Ember.Route.extend(
          # This route is routable because it is a leaf route.
          route: '/:project_id'

          connectOutlets: (router, project) ->
            # Render the project into the second column, which actually renders
            # a list of collaborators.
            router.get('projectsController').connectOutlet('project', project)
        )
      )
    )
  )
)

正如你所看到的那样Ember不会调用updateRoute(设置URL),直到转换到root.projects.show这条线为止https://github.com/emberjs/ember.js/blob/master/packages/ember-routing/lib/routable .js文件#L81

还有其他人做过这样的事吗？有没有更好的方法来设计它？

我发现这样做的最好方法是让一个root.projects.index状态的路径为"/",而不是别的.这样每个页面都有自己的特定状态.

projects: Ember.Route.extend(
  # This route is not routable because it is not a leaf route.
  route: '/projects'

  connectOutlets: (router) ->
    # List projects in left column
    router.get('applicationController').connectOutlet('projects', App.projects)

  index: Ember.Route.extend(
    route: "/"
  )

  show: Ember.Route.extend(
    # This route is routable because it is a leaf route.
    route: '/:project_id'

    connectOutlets: (router, project) ->
      # Render the project into the second column, which actually renders
      # a list of collaborators.
      router.get('projectsController').connectOutlet('project', project)
  )
)

NB那就是说我正在用3列布局做类似的事情,并且将中间和右列与上面的路线匹配,并将共享布局中的左列添加到每个可能的中间视图中.
