属性分配是否有可能使Ember.js中的控制器链冒泡？

Question

I have a resource creation controller/view, and the resource belongsTo another. An element of the view is a shared Component that contains nested resource index and filter/pagination logic. I'd like to override the context of the sub-resource's indexController such that when an instance is selected, it is assigned to the parent controller rather than the controller itself.

While ember bubbles action events up the controller hierarchy, it errors out if a property is undefined. Also, it delegates properties from the view to the controller if undefined in the view.

This seems like it might be a common pattern. Perhaps implicit bubbling is not ideal, but is there a best practice (or should there be a way) to enable any undefined references to bubble up to a parent?

Answer 1

If the nested controllers/views are just UI elements (do not need to have special model) than I suggest to not implement special controllers for these nested views. I mean try to implement just the views and render them in a parent template using Handlebars {{#view App.YourView}} helper which binds current controller (the parent one) as a model to the view so you can access the parent model.
