What is the process for removing information from Firebase?

I am currently working on a project using Firebase along with AngularJS. The issue I am facing is deleting a randomly generated ID in the Realtime Database.

var todoFirebaseID;
// Insert Firebase
$scope.addFirebase = function() {
    var objects = {
        title: objectTitle.value,
        content: objectContent.value
    }

    var list = $firebaseArray(storageRef);
    list.$add(objects).then(function(storageRef) {
        todoFirebaseID = storageRef.key;

        $scope.addTodo();
    });
}
// Delete Firebase
$scope.removeFirebase = function() {
    var obj = $firebaseObject(storageRef);
    obj.$remove().then(function() {

    });
}

I have attempted to implement this functionality, but the issue is that it deletes all the data in Firebase instead of just the selected data. I am seeking guidance on how to resolve this issue. Can anyone provide a solution?

Answer №1

When you command Firebase to delete the entire database, it will do just that. To only remove a single item, you need to use the $remove() function on that specific item.

The code snippet you provided shows the process of deleting an item:

$scope.removeFirebase = function() {
    var obj = $firebaseObject(storageRef.child(todoFirebaseID));
    obj.$remove();
}

This code is referencing the child item with the todoFirebaseID.

In a practical application, you would set up an event handler for when the user clicks the delete button. This handler would then determine the ID of the item the user wants to delete.
