Update value in Parse.com - swift

Question

I am trying to update a value in my Parse.com table named: "currentUploaded".
This is my query from Parse.com code:
http://pastebin.com/Jr0EcJuy
Parse.com “currentUploads” class: http://i.stack.imgur.com/E8tND.png
This is the button i want to do the update value(as it is now, it create a new row in another class, but i just want to increase the "reportedCount" of the selected item instead:
#IBAction func reportContentAction(sender: AnyObject) {
let buttonPosition = sender.convertPoint(CGPointZero, toView: self.collectionView)
let indexPath = self.collectionView.indexPathForItemAtPoint(buttonPosition)
////
println(indexPath?.item)
////
let post = self.arrayOfDetails[indexPath!.item]
var alertMessage = NSString(format:"*User: %#\r *Text: %#\r *Created at %#", post.username, post.text, post.CreatedAt)
var reportAlert = UIAlertController(title: "Report Content", message:alertMessage as String, preferredStyle: UIAlertControllerStyle.Alert)
reportAlert.addAction(UIAlertAction(title: "Yes", style: .Default, handler: { (action: UIAlertAction!) in
println("Handle Report Logic here")
var currentUploads = PFObject(className: "banned")
currentUploads["username"] = post.username
currentUploads["imageText"] = post.text
currentUploads["imageFile"] = post.image
currentUploads["identifierForVendor"] = post.deviceID
currentUploads["flaggedBy"] = PFUser.currentUser()?.username
currentUploads["flaggedByUUID"] = UIDevice.currentDevice().identifierForVendor.UUIDString
currentUploads.saveInBackgroundWithBlock({ (success: Bool, error: NSError?) -> Void in
if error == nil{
//**Success saving, now save image.**//
currentUploads.saveInBackgroundWithBlock({ (success: Bool, error: NSError?) -> Void in
if error == nil{
// Take user home
print("Data uploaded")
// Show UIAlertView
let alert = UIAlertView()
alert.title = "Message"
alert.message = "You report has been sent. Thank you for your support."
alert.addButtonWithTitle("Close")
alert.show()
}
else{
print(error)
}
})
}
else{
print(error)
}
})
}))
reportAlert.addAction(UIAlertAction(title: "Cancel", style: .Default, handler: { (action: UIAlertAction!) in
println("Handle Cancel Logic here")
}))
presentViewController(reportAlert, animated: true, completion: nil)
}
I have also tried using this code when the user click yes on the popup, but it doesn't work:
reportAlert.addAction(UIAlertAction(title: "Yes", style: .Default, handler: { (action: UIAlertAction!) in
println("Handle Report Logic here")
var query = PFQuery(className: "currentUploads")
query.whereKey("imageFile", equalTo: post.image)
query.getFirstObjectInBackgroundWithBlock {
(myObject: PFObject?, error: NSError?) -> Void in
if (error != nil){
println(error)
//
}
else{
query.setValue("1", forKey: "reportedCount")
}
}
}))
Please, can someone show me how it should be correct? Have been struggling on this for many many hours now..

Answer 1

a small example
let someQuery = PFQuery(className: "banned")
someQuery.getObjectInBackgroundWithId(someclass.objectId) {
(updatedObject: PFObject?, error: NSError?) -> Void in
if error != nil {
print(error)
} else if let updatedObject = updatedObject {
updatedObject["NameOfTheFieldYouWantToChange"] = newValue
updatedObject.saveInBackground()
}
}
someclass.objectId — it's just an objectId value for the raw you want to update. I don't know where you are storing it.
"NameOfTheFieldYouWantToChange" — name of the field you want to change :)
newValue — new value for this field.
P.S. Also it seems that you are trying to put your Parse code to your ViewController class. Compiler won't care so it will work, but it's not a good practice. It would be much more simpler for you to put all these database operations to different class (MVC pattern).
