ios - parse.com wherekey doesnotmatchkey in query 不过滤对象

Question

I have Parse classes Doctor->name,clinic,address... Patients-> name,phone... Appointments-> Doctor,patient,Date

我正在尝试运行子查询以返回在特定日期没有任何预约的医生的记录

    let queryDoctor = PFQuery(className: Doctor.parseClassName())
    let queryAppointment = PFQuery(className:Bookings.parseClassName())
    queryDoctor.whereKey("objectId", doesNotMatchKey:"Doctor.objectId", inQuery: queryAppointment)
    queryDoctor.findObjectsInBackgroundWithBlock 
    {
        (results: [PFObject]?, error: NSError?) -> Void in
        print(results)
    }

但查询似乎没有考虑PFQuery 的wherekey 方法就返回了所有医生的记录。任何建议？

使用:

queryDoctor.getObjectInBackgroundWithId(etc...

希望对你有帮助
