Angular utilizes array format to store data in the $scope

Question

Angular utilizes array format to store data in the $scope

I am working on an Angular test application where I am trying to retrieve data from a PHP page into my model. The response comes using the echo json_encode($arr); command in the PHP file and has the format

[{"id":"1","name":"first","text":"description"}]

. To successfully receive this data in my model, I have to use a query because .get is giving me an error. In my controller, my query looks like this:

$scope.item = Items.query({id:$routeParams.id});

When trying to use this data in my model, I need to specify my array item[0].name, which is not a problem. However, when attempting to save edited data, I encounter an error:

$scope.item[0].$save({id:$scope.item[0].id});

The error message I receive is TypeError: Object # has no method 'push'

What could I be doing wrong?

When setting up the resource correctly, saving should be as simple as calling:

$scope.item[0].$save();

However, it appears that this is not being done. When using query, it typically returns an array. Since you are querying for a single ID, it is more appropriate to use the get method:

$scope.item = Items.get({id:$routeParams.id});
...
// Modify $scope.item as necessary
...
$scope.item.$save();

The easiest way to define a resource is by utilizing the default actions provided by Angular:

.factory('Items', function($resource) {
    return $resource('/angular/angular-seed/app/questions/php/maintext.php');
});

According to the Angular Documentation:

The default set contains these actions:
{ 'get':    {method:'GET'},
  'save':   {method:'POST'},
  'query':  {method:'GET', isArray:true},
  'remove': {method:'DELETE'},
  'delete': {method:'DELETE'} };
