[Firebase + Angular] Parsing the information from firebase. The keys are in a "dict"... Angularfire...

Hey folks,

I'm missing something.

I've got a something from firebase which I can iterate on in the
template, but I'd like to monkey with the data in the controller. But
maybe that's not ok?

The problem is the keys:


- * -3*
- * -JSVkOs7vCXh1iBAzxsi: *74
-
- * -2*
- * -JSVnT2OqIdZ3IvJ2zjd: *4

It ends up looking like {*-JSVkOs7vCXh1iBAzxsi: *74} in the code. How
do I peel off the value and ignore the unique key either in the controller
or in the template?

Thanks!

Jaems

Hey James,

It looks like you are trying to use arrays. Lucky for you, we are
greatly improving the AngularFire array support (among many other things)
with our upcoming 0.8 release. The new $FirebaseArray will save you a
lot of time. While it will be another week or so until we officially launch
0.8, the API is practically frozen and I'd suggest moving to it, especially
if this is a new project. It will save you a lot of time. You can grab the
code in our release_0.8 branch on GitHub
<https://github.com/firebase/angularFire/tree/release_0.8>. Here are
the current API docs
<http://firebase.github.io/angularFire/flatdoc.html> to get you
started. Check out our examples for $FirebaseArray.

If you do want to do this in 0.7.x, you should check out our
orderByPriority example in our API documentation
<https://www.firebase.com/docs/angular/reference.html#orderbypriority>:

<ul ng-repeat="item in items | orderByPriority">
<li>
<input type="text" id="{{ item.$id }}" ng-model="item.$priority" />
{{ item.name }}
</li>
</ul>

The item value within each loop iteration should contain what you want.

Hey Jacob,

I just read through the Firebase 0.8.0 docs. Are these changes breaking
(i.e., I can't just use 0.8.0 with my 0.7.x app)?

Upon a quick first glance at the docs, it looks that way. For example,
instead of saying $scope.items = $firebase(ref), I need to specify whether
it's an array or an object everywhere I do this. It also looks like $add
has been replaced by $push in some circumstances.

If that's the case, is there any guarantee that the changes in 0.8.x
will carry all the way through to a stable 1.0 release? If not, should we
just keep the app frozen at 0.7.x and wait to port over everything when
things settle down a bit?

Best,
Jake
