$resource adds some things to the json string returned from the server?

[Thai]

Hi All,

I'm learning angularjs 1.2.5 and this is what I notice:

html: <button ng-click="testJAXRS()">testing jax-rs with ng-click</button>

js:
var app = angular.module("myApp", ["ngResource"]);
app.controller("Controller", ["$scope", "$resource", function($scope, $resource) {
    $scope.testJaxRS = $resource("${pageContext.request.contextPath}/resource/test-jaxrs/something");

    $scope.testJAXRS = function() {
        var temp = $scope.testJaxRS.get(function() {
            alert(JSON.stringify(temp));
        });
    };
}]);

The json string returned from the server is {"key 1":["value 1 for key1","value 2 for key1"],"xyz":["abc","def","mnp","something"]}, but the alert prints out {"key 1":["value 1 for key1","value 2 for key1"],"xyz":["abc","def","mnp","something"],"$promise":{},"$resolved":true}. Is there any way to not have the "$promise" and "$resolved" keys in the variable temp?

Thanks.

Just curious, but why is this a problem? Also, angular.(to|from)Json handle this case for you by taking out $-prefixed properties.

Thanks, Jeff, for the angular.(to | from)Json. So, if I want to remove all the $-prefixed keys, I have to use something like angular.fromJson(angular.toJson(temp)), right?

This might be a problem if I want to display the content of the variable temp on the screen.

You generally don't need to worry about this. The json filter removes those properties by default (I believe) and your view should know what properties it needs to display so it should never have to worry about those properties.

This is part of the changes to $resource. To remove those, change your resolution code from '.$then()' to '.$promise.then' and you'll get what you used to get.

Even when using '.$promise.then' you will still get the $promise and $resolved properties in 1.2.7. Is there a way to remove them for all resource calls? I don't want to have to write this everywhere:
