I am trying to make an ajax call using $resource and load a datatable upon receiving the data from a server. But when I call a get() then I am getting $promise as undefined. I am using a factory to make the call. Here is my factory :
app.factory('getAllUsers', [ '$resource', function($resource) {
return $resource('URL', {}, {get : {method : 'GET'}});
}]);
And the controller :
app.controller('MyController',function($scope,$location,getAllUsers){
console.log("In controller");
getAllUsers.get().$promise.then(function(data) {
loadDatatable(data);
});
});
ERROR : getAllUsers.get().$promise is undefined
NOTE : I have included ngResource in my app and angular-resource.js in index.html too.
The $resource service doesn't return promises in version 1.0.x; be sure to read the correct version of the docs. By default, http://docs.angularjs.org/api/ is for the 1.2.x series, which is currently unstable. Try this version of the api docs: http://code.angularjs.org/1.0.8/docs/api
Since you are using $resource you can do
getAllUsers.get({},function(data) {
loadDatatable(data);
});
Did you forget to add .json as type of call?
app.factory "User", ["$resource", ($resource) ->
$resource("/users/:id.json", {id: "@id"}, {update: {method: "PUT"}})
]
