Trying to validate that an array value only contains certain elements.



The "focus" key, should only contain any or both of the following: "movement", "strength".



So I tried sending this: 



{

  "focus": ["movement"]

}


... and the security rules: 



 "$id": {

    "focus" : {

        ".validate": "newData.hasChild('movement') || newData.hasChild('strength') || newData.hasChildren(['strength', 'movement'])"

    }

}


But get "Simulated update denied" and cannot understand why.



Thanks in advance

          Full-time equivalent From Wikipedia, the free encyclopedia Jump to navigation Jump to search Full-time equivalent ( FTE ) or whole time equivalent ( WTE ) is a unit that indicates the workload of an employed person (or student) in a way that makes workloads or class loads comparable [1] across various contexts. FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load.
