Swift Parse query multiple table and output into PFtableviewcell

Okay, let say I have 2 table in Parse, how do i query both of them and show it into PFtableviewcell?

Table 1: User
Column: username, email, address

Table 2: Request
Column: item_wanted, username

Note: username in Table2 is a "pointer" that point to Table 1 (you must use pointer)

import UIKit

import Parse

import ParseUI

class TableViewController2: PFQueryTableViewController {

override func queryForTable() -> PFQuery {

        var query = PFQuery(className: "Request")

        query.includeKey("username")

        return query

    }

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell {

        

        var cell = tableView.dequeueReusableCellWithIdentifier("Cell") as PFTableViewCell!

        if cell == nil {

            cell = PFTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")

        }

         if let myrequester = object?["username"] as? PFObject

        {

            if let myusername = myrequester["username"] as? String

            {

                   cell.textLabel?.text = myusername

            }

        }

        

     

        

        if let mysubtitle = object?["item_wanted"] as? String 

       {

            cell?.detailTextLabel?.text = mysubtitle

        }

        

        return cell

        

        

    }

}

Key Note 1: You must use query.includeKey("username"), this mean you want Parse to include all the data from the table "User" using the key "username"

Key Note 2: Since it is double layer, you query table "Request" then into table "User" , so you need to access the data double layer

 if let myrequester = object?["username"] as? PFObject

        {

            if let myusername = myrequester["username"] as? String

            {

                   cell.textLabel?.text = myusername

            }

        }

you access the object["username") to get to the table "User" then you need to do it one more time myusername = myrequester["username"] 

hopefully I can help you in anyway, cheers
