I get “Assertion failed: You must include an `id`

Question

I must have read every question on stack overflow regarding my issue and have not found a solution. I am very new to Ember and Node so please bear with me.

The server responds with this format:

{
"_id" : "53fddf59d72f9b4d3a3e164a"
"about" : [
    {"from" : "foo"},
    {"text" : "bar"},
    ... ]
}

My model looks like this:

App.About = DS.Model.extend({
    from : DS.attr('string'),
    text : DS.attr('string'),
    ...
}

Adapter & serializer:

App.ApplicationAdapter = DS.RESTAdapter.extend({
    host: 'http://localhost:3000'
});

App.ApplicationSerializer = DS.JSONSerializer.extend({
    primaryKey: '_id'
});

And my route:

App.AboutRoute = Ember.Route.extend({
    model: function() {
        return this.store.find('about');
    }
});

Using handlebars:

<script type="text/x-handlebars" data-template-name="about">
    <p>{{from}}</p>
</script>

The route will render, but the console gives the error:

DEBUG: ------------------------------- ember.js:3285

Assertion failed: You must include an id in a hash passed to push ember.js:3285

Transitioned into 'about'

What am I doing wrong?!

Update:

Have accepted Kingpin2k's answer even though this was not the exact format I ended up using. See the comments for details.

Answer 1

Your format should have the type plural, and the id on the individual records.

 {
  "abouts" : [
    {
     "from" : "foo",
     "text" : "bar",
     "_id" : "53fddf59d72f9b4d3a3e164a"
    },
    {
     "from" : "foo2",
     "text" : "bar2",
     "_id" : "53fddf59d72f9b4d3a3e164k"
    },
    ... ]
 }
