Ember.js计算属性以返回模型ID数组？

Question

Updated: 11:36PST 07 Dec 2017

All I'm trying to do is create an array containing a list of current ID's in the model to use in a child component, but somehow seem to be missing something obvious. If it is relevant, I am using Ember 2.17.0 with Ember Data 2.17.0 as well.

The route returns an array of models very similar to a findAll , but modified to work with a REST endpoint I do not have any control over. I need an array of the id's from the model to use in a component embedded in the route. Based on feedback, I have attempted to implement this in both the route and the controller.

In the controller, I'm trying it this way.

searchIdArrayC: computed('model', () => {
  return this.get('model').map((record) => record.get('reachId'));
})

..and in the route I'm trying it this way.

searchIdArrayR: computed('model', () => {
  return this.modelFor('reaches').map((record) => record.get('reachId'));
});

When I look at it in the Chrome Ember Inspector, for both the route and controller it is telling me Error while computing: searchIdArrayR or Error while computing: searchIdArrayC .

Just to try and do some testing, I sent both the route and the controller to the console. With both the route and controller, the aforementioned methods are working, so I am really confused.

Thank you in advance for any help or guidance you may be able to offer.

Answer 1

In route file, model is a function, but you are treating it like model property which is available in the corresponding controller.

If you can move searchIdArray computed property to corresponding controller then that should work.
