Navigating JSON responses in Angular: A comprehensive guide

I am currently working with the following controller:

function EntryCtrl($scope, Restangular){
 console.log("*** EntryCtrl");
 $scope.roles= Restangular.all("roles").getList();
 console.log("*** EntryCtrl: " +  JSON.stringify($scope.roles));
}

After running this code, the console output displays:

*** EntryCtrl: {"restangularCollection":true} 

However, when I use a rest browser plugin to make the same rest call, the response is:

[
 {
     "name": "dev"
 }
]

I am struggling to find a way for Angular to process the response in the same way as the rest browser plugin does. My main objective is to extract and display the role name, "dev", using Angular. I would like to implement an Angular page that uses "ng-show" on a link based on the role name. Here's an example of how I want to achieve this:

<a href="" ng-show="roles.contains('')>Foo</a>

Answer №1

Give it a shot with

$scope.roles= Restangular.all("roles").getList().$object;

Check out more information on this in the documentation

Performs a GET request to /accounts Initially returns an empty array, but populates it with data from the server response You can then utilize this array within your template

$scope.accounts = Restangular.all('accounts').getList().$object;

Answer №2

When referring to the documentation:

The method Restangular utilizes promises, stepping away from automatically populating objects like $resource

To obtain the server's response, the .then callback must be used in the following manner:

Restangular.all("roles").getList().then(function(response){
    $scope.roles = response;
});

Additionally, within your template:

<li ng-repeat="role in roles">{{role.name}}</li>
