Question

Intento llevar un nuevo registro a mi Firebase. Pero cada vez que recibo un error de consola como este:

$scope.contacts.$add is not a function

Aquí está mi código:

app.controller(''contactsCtrl'',[''$scope'',''$firebaseObject'',function($scope,$firebaseObject){

 var ref = new Firebase("https://<database_details>.firebaseio.com/contacts");

 $scope.contacts = $firebaseObject(ref)

 $scope.addContact = function(){

     $scope.contacts.$add({
        name: $scope.name,
        address: $scope.address,
        telephone: $scope.telephone,
        company: $scope.company,
        email: $scope.email
        }).then(function(ref){

        var id = ref.key();
        console.log(''contact added with Id: '' + id);


    });

        }; 
  }]);

Answer 1

Debería usar $firebaseArray lugar de $firebaseObject

app.controller(''contactsCtrl'',''$scope'',''$firebaseArray'',function($scope,$firebaseArray){
 var ref = new Firebase("https://<database_details>.firebaseio.com/contacts");
 $scope.contacts = $firebaseArray(ref)
 $scope.addContact = function(){
     $scope.contacts.$add({
        name: $scope.name,
        address: $scope.address,
        telephone: $scope.telephone,
        company: $scope.company,
        email: $scope.email
        }).then(function(ref){
        var id = ref.key();
        console.log(''contact added with Id: '' + id);
    });
   }; 
  }]);
