AngularJS push to array parse in view - angularjs

Question

I have a controller where I declare the model like this:
$scope.Model =[];
after I make a rest call and the result I push it to the model:
$scope.Model.push(results.data);
The data returned can be in different length and size:
Name
Email
Items
Item 1
Item 2
Item n
Roles
Role 1
Role 2
Role n
What is the best practice of handling this with arrays in AngularJS and using ng-repeat in view in order to show the data?
Should I declare my array like this:
$scope.Model =[];
and push the results:
$scope.Model.push(results.data);
or like this:
$scope.Model =[{
Name: '',
Email: '',
Items: [{
Id: '',
Name: '',
Price: ''
}],
Roles: [{
Id: '',
Name: ''
}],
}];
and asign the results:
$scope.Model = results.data;

Answer 1

It is based on your response and scenarios. but ng-repeat expects Array or Array list.
1) Array
Example 1 (plain array response)
$scope.names= ["Apple", "Banana", "Orange"];
<ul>
<li ng-repeat="x in names">
{{ x }}
</li>
</ul>
Example 2 (Object response that has array)
$scope.names= {
"fruits": ["Apple", "Banana", "Orange"]
};
<ul>
<li ng-repeat="x in names.fruits">
{{ x }}
</li>
</ul>
2) Array List
Example 1 (plain array list response)
$scope.names = [{
"id": "1",
"name": "Asik"
},
{
"id": "1",
"name": "John"
},
{
"id": "1",
"name": "Smith"
}];
<ul>
<li ng-repeat="x in names">
id:{{ x.id }}, name:{{ x.name }}
</li>
</ul>
Example 2 (Object response that has array list)
$scope.names = {
"success": "true",
"items": [{
"id": "1",
"name": "Asik"
},
{
"id": "1",
"name": "John"
},
{
"id": "1",
"name": "Smith"
}]
};
<ul>
<li ng-repeat="x in names.items">
id:{{ x.id }}, name:{{ x.name }}
</li>
</ul>
Basically, service/ajax response comes as Array or Array list. So you don't need to do the following steps.
$scope.Model =[];
$scope.Model.push(results.data);
But the above case comes in some situation (for eg: merging 2 service/ajax responses )

Answer 2

I have used the following:
angular.copy(results.data, $scope.Model)
This will actually copy the results from the rest servicve into my model without having to declare each property of the model.
