What is the process for adjusting views to avoid using the default container in Ember JS?

I am faced with the challenge of dynamically creating and inserting a view into my Ember app (specifically off master - v1.0.0-rc.3-178-ge031b24). Recently, this view has been triggering the following notice:

DEPRECATION: Using the defaultContainer is no longer supported. [defaultContainer#lookup]

I have tried to modify my current implementation to address this issue, but so far, I have not found the right solution.

Currently, during route setup, I am attaching a new ViewContainer to the controller:

App.ThingRoute = Em.Route.extend
  setupDetailContainers: (controller) ->
    controller.set('imageContainer', Em.ContainerView.create())
    controller.get('imageContainer').appendTo(App.rootElement)

Then, in the controller, when users click on an image thumbnail, the full-size image is inserted using:

showFullImage: (image) ->
  image_full = image.asset_url.replace(':size', 'original')
  container = @get('imageContainer')
  container.pushObject App.ShowImageView.create({image: image_full})

If anyone has any advice on the correct approach to eliminate these deprecation warnings, it would be greatly appreciated.

Answer №1

Dealing with a similar issue here, except I encountered it prior to the deprecation warning and instead received an error from Ember.

The key takeaway is to utilize createChildView within the parent view where you intend to create the child in order to establish the correct parent-child relationship.

Answer №2

After updating to v1.0.0-rc.3-292-g39e9ef7, I encountered a problem that stemmed from defining a childView using create() instead of extend(). An example of my initial code:

App.FooView = Ember.View.extend({
    templateName: 'fooTemplate'
    , childViews: ['barView']
    , barView: Ember.View.create({
        ... bindings and stuff ....
    })
    .... more and more ....
});

The notice I kept receiving disappeared when I modified the line:

    , barView: Ember.View.create({

To:

    , barView: Ember.View.extend({

I wanted to share this solution in case others face a similar issue.
