AngularFire $remove item from Array using a variable in Firebase reference does not work

Question

I\'ve been struggling with the following problem:

I\'m trying to delete a \'Post\' item from a Firebase Array with the $remove AngularFire method which I have implemente

Answer 1

The easiest way for me was to use this:

var ref= new Firebase('https://Yourapp.firebaseio.com/YourObjectName');
ref.child(postId).remove(function(error){
    if (error) {
    console.log("Error:", error);
  } else {
    console.log("Removed successfully!");
  }
});

Answer 2

The only way I'm able to remove the item is using a loop on the array we get from firebase.

var ref= new Firebase('https://Yourapp.firebaseio.com/YourObjectName');
var arr_ref=$firebaseArray(ref);
    for(var i=0;i<arr_ref.length;i++){
        if(key==arr_ref[i].$id){
            console.log(arr_ref[i]);
            arr_ref.$remove(i);
        }
    }
