Ember：在Mixin中编程设置queryParams

问题描述

mixin有一个方法，当控制器保持mixin被初始化时，该方法被调用。

c $ c> queryParams 的后期绑定是不可能的。

I'm trying to programatically define queryParams in an Ember.Mixin.

The mixin has a method which is called when the controller holding the mixin is initialized.

setupQueryParams: (params) ->
  params.forEach (param) =>
    @get('queryParams').push(param)

Later in an action defined on the mixin I call @transitionToRoute({queryParams: {someParam: 'something'}}) nothing happens. However when I explicitly define my queryParams, this works.

解决方案

queryParams are resolved off the proto of the class, not an instance, so any init functionality wouldn't be applied in time for ember to resolve it.

This just means late binding of the queryParams isn't possible in the way you want.
