Incorrect JSON format for Ember Data

I'm using the latest version of EmberJS and Ember Data. I have the next JSON data:

[{
    "id": 6,
    "name": "First object",
    "vol": 40,
    "description": "bla bla bla",
    "category": "first"
}, {
    "id": 7,
    "name": "Second object",
    "vol": 17,
    "description": "Some description",
    "category": "second"
}]

And the next model:

import DS from 'ember-data';

export default DS.Model.extend({
  name: DS.attr('string'),
  vol: DS.attr('number'),
  description: DS.attr('string'),
  category: DS.attr('string')
});

And I don't understand how to make Ember data works. I have suspicious that ember data expects something like next:

[{ 
    model-name {
        "id": 6,
        "name": "First object",
        "vol": 40,
        "description": "bla bla bla",
        "category": "first"
    }
}, { 
    model-name {
        "id": 7,
        "name": "Second object",
        "vol": 17,
        "description": "Some description",
        "category": "second"
    }
}]

In console I have a bunch of warnings:

WARNING: Encountered "0" in payload, but no model was found for model
name "0" (resolved model name using emdber-drink-
it@serializer:application:.modelNameFromPayloadKey("0"))
WARNING: Encountered "1" in payload, but no model was found for model
name "1" (resolved model name using emdber-drink-
it@serializer:application:.modelNameFromPayloadKey("1"))

And more than hundred similar records (that is how many records server returns on request). And no data in store.

How can I fix this problem without changing JSON that I receive from server?
