contentBinding is Superfluous about ember_data_example

[dgeb]

It's a bit tricky. The sole reason for that contentBinding is to ensure that isActive() can be evaluated in App.ContactInListView. If you remove it, the active contact will no longer be highlighted, because the view won't have access to the contact.

The reason that the contacts still appear in the list properly is that the template contact_in_list.hbs has access to the contact var from its parent, and so it can evaluate:

{{#linkTo "contact" contact}}{{contact.fullName}}{{/linkTo}}

Some of these context differences between templates and views can be a bit subtle and confusing.

I have to say I'm really struggling with Ember. There is so much out there that is out of date or subtly wrong and very little in the way of best practices. I can see that Ember is a really great thing, but I'm not much enjoying learning it from the scraps I can find. Thanks again for this example. It's been really helpful.

@1ndivisible Take heart - Ember's 1.0 API stabilized just over a month ago. I think that you'll see a wave of new guides, tutorials and examples now that much of the churn is behind us. In fact, I'm just getting the tests in order for this project and will be doing a series of blog posts based on it soon.
