If I have a standard Post resource (model) and in my index action have: # GET /posts # GET /posts.json def index @posts = Post.all render json: @posts end and there's only 1 post in @posts, I get back something like [{"id": 1, "title":"ImaPost"}] but I (think I) want to get back something more like {"posts": ["Post":{"id": 1, "title":"ImaPost"}]} The reason I am trying to do this is because I am follow this tutorial [this video] for using an api with swift for iOS dev, but it's my first time creating an API and its my first time using something like this with swift.
Cites SagittariusA · 2015-08 · Stack Overflow · on “Swift: How to use NSURLSession to query external database?”
I am writing this question because I am in a big difficulty in understanding how to implement a simple basic authentication login with Swift. The first screen of my app is a simple form with text fields (username and password) and a Sign In button. In my LoginViewController.swift file I linked the button to this: @IBAction func doLogin(sender : AnyObject) { } The probem now is that I don't know how to go on. I have a local server in MAMP where there is this file.php querying a database and which works perfectly: <?php $deep=""; require_once($deep."class/config.php"); $sistema = new config($deep); if( isset($_GET["username"]) && isset($_GET["password"]) ) { $username=mysqli_real_escape_string
