I can use the following to add an object to my Firebase data store:
var uniqueId = {
name: "a name",
location: "new york"
}
$scope.myItems.$add(uniqueId).then(function(firebaseId){
// do something on success
}, function(){
// do something if call fails
});
The above will add an object into my data store and if the add is successful, an ID generated by Firebase is returned. The object I just added is saved under this key.
Is there a way for me to specify what the key name is when I add to my data store?
Take the following URL for example.
https://myapp.firebaseio.com/users/
Let's say we want to create a user with a key of 1 as a child at this location. Our URL would look like this.
https://myapp.firebaseio.com/users/1
To create a user using AngularFire we can create a reference at the users node and call $child(1) to create a reference to that location.
var usersRef = new Firebase('https://myapp.firebaseio.com/users');
var userRef = new Firebase('https://myapp.firebaseio.com/user/1');
$scope.users = $firebase(usersRef);
// these are the same
$scope.userOne = $firebase(userRef);
$scope.userOne = $scope.users.$child(1);
Then we can use $set
to store the value of the user at that location.
var usersRef = new Firebase('https://myapp.firebaseio.com/users');
$scope.users = $firebase(usersRef);
$scope.users.$child(1).set({
first: 'Vincent',
last: 'Van Gough',
ears: 1
});
In your case it would be:
var uniqueId = {
id: 1,
name: "a name",
location: "new york"
};
$scope.myItems.$child(uniqueId.id).$set(uniqueId);
Remember that using $set
will destroy any previous data at that location. To non-destructively update the values use $update
.
