我試圖將「類」中的對象設置爲「學校」中的對象。當我這樣做,我得到這個錯誤:將分析指針設置爲PFUser以外的類
invalid type for key school, expected *Schools, but got string (Code: 111, Version: 1.12.0)
我知道錯誤是說,它預計類的指針,「學校」,但它有一個字符串代替。這裏是我的代碼:
let schoolObjectIdQuery = PFQuery(className:"Schools")
schoolObjectIdQuery.whereKey("school_name", equalTo: "\(PFUser.currentUser()!.objectForKey("school_name")!)")
let query = PFQuery.orQueryWithSubqueries([schoolObjectIdQuery])
query.findObjectsInBackgroundWithBlock({ (results: [PFObject]?, error: NSError?) -> Void in
if let objects = results {
for object in objects {
let schoolObjectId = object.objectId!
//////////////////
let classInfo = PFObject(className: "Classes")
classInfo.setObject(className!, forKey: "class_name")
classInfo.setObject(teacherName!, forKey: "teacher_name")
classInfo["school"] = schoolObjectId
classInfo.saveInBackgroundWithBlock({ (success:Bool, error:NSError?) -> Void in
if error != nil {
spinningActivity.hideAnimated(true)
self.displayAlert("Error", message: error!.localizedDescription)
print(error?.localizedDescription)
}
else if success {
spinningActivity.hideAnimated(true)
self.dismissViewControllerAnimated(true, completion: nil)
}
else {
self.displayAlert("Something Went Wrong", message: "Please try again")
}
})
}
}
})
上面的代碼查詢正確的「學校」對象的OBJECTID數據,然後設置到另一個類,「類」,爲此,我需要的OBJECTID從「學校」目的。 *我知道我的錯誤處理還沒有正確設置
如果我用classInfo["school"] = PFUser.currentUser()
替換classInfo["school"] = schoolObjectId
指針發送到Parse沒有問題。我如何在類「Schools」中將指針設置爲「school_name」作爲指針而不是字符串?
在此先感謝您的幫助!
謝謝!這正是我發佈後想到的。我稍後再嘗試一下,並將其標記爲正確的答案 –
