{{＃link-to'routeName'}}与动态上下文 [英] {{#link-to ‘routeName’}} with dynamic context

问题描述

可以将链接到动态上下文参数作为单个变量使用吗？

Is it possible to use link-to with dynamic context params as a single variable?

当有1个动态部分时，这可以工作，但在下面的示例中 post-category-id 和 post-id 。是否可以动态地传递这些参数。它尝试将它们作为数组或String传递，但这不起作用。

This works when there is 1 dynamic part, but in the example below i have post-category-id and post-id. Is it possible to pass these params in dynamically. It tried to pass them as array or as a String, but this is not working.

在示例中，我想要 {{link- postparams}} 其中帖子嵌套在后类别中。我的目标是通过所需的2个上下文参数传递参数。

In the example I want to {{#link-to "post" params}} where post is nested in post-category. My goal is to pass in params with the 2 context params needed.

// router
this.resource('post-categories', {path: 'post-categories/:post-category-id'}, function() {
  this.resource('post', {path: 'post/:post-id'})
});

// controller
...
  params: Em.computed(function() {
    return [1, 4]
  })
...

// template
{{#link-to "post" params}}

我尝试在源代码中阅读，但这并没有太大帮助。

I tried to read in the source, but that didn't help too much.

推荐答案

好的，我的解决方案通过控制器上的动作。
在此操作中，我检查我的参数的长度，并切换到 transitionToRoute ，并具有所需的动态部件数量。虽然不是刚刚干了。

Okay, my solution goes through an action on the controller. In this action I check the length of my params and switch case transitionToRoute with the desired amount of dynamic parts. Though not verry DRY.

switch (params.length) {
  case 0: 
    this.transitionToRoute(route.get('routeName'))
  break;
  case 1: 
    this.transitionToRoute(route.get('routeName'), params[0])
  break;
  case 2: 
    this.transitionToRoute(route.get('routeName'), params[0], params[1])
  break;
  case 3: 
    this.transitionToRoute(route.get('routeName'), params[0], params[1], params[2])
}
