AngularFire / Firebase - How Do You Delete Key That is More Than One Level Deep? -

i have synced object initialized this:

var sync = $firebase(ref); var syncobject = sync.$asobject(); syncobject.$bindto($scope, 'data'); 

the synced object has following structure:

{     levelone: {         leveltwo: {             valueone: 1             valuetwo: 2         }     } } 

i remove 1 of values $remove(), not able delete other entire object method.

the following delete entire object:

syncobject.$remove('levelone.leveltwo.valueone'); 

i not want use $save() overwrite entire synced object.

is there anyway remove nested key $remove()?

there no way drill through multiple layers $remove() function. ended using vanilla firebase js library methods delete.

var ref = new firebase(myfirebaseurl); // child() method (from vanilla js library) allows target keys  // more 1 level deep ref.child('levelone/leveltwo/valueone').remove(); var sync = $firebase(ref); 

you can chain child() function off of original js firebase class object , run remove() method off of (notice remove() method , not $remove() method).
