[SOLVED] PFQueryTableViewController query pointer to User class and put as username label in table (Swift, Parse)

PFQueryTableViewController query pointer to User class and put as username label in table (Swift, Parse)

I'm making a twitter type app with Parse and Swift language.

Users are able to make posts that are displayed in a PFQueryTableViewController using the queryForTable function. One of the columns in my "Posts" class is a pointer to the "User" class and I want to be able to query this pointer and display the usernames of the users in labels next to their posts in the tableview/timeline.

How do I query this pointer and extract the username from the User class it points to as a string to put in the username label?

here is my code so far:

    override func queryForTable() -> PFQuery {

    let query = PFQuery(className: "Posts")
    query.cachePolicy = .NetworkElseCache
    query.orderByDescending("createdAt")
    return query
}

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

    let cell = tableView.dequeueReusableCellWithIdentifier("postCell", forIndexPath: indexPath) as! ResponseTableViewCell

    cell.usersPostLabel.text = object?.objectForKey("postContent") as? String



    return cell
}

Solution

You may access the user pointer information with:

object?.objectForKey("User")!.objectForKey("username") as? String

Also, make sure you are receiving the User information on your request. So include this when querying:

query.includeKey("User")
