    <p>I hope you can help me. I'm trying to fetch datas from my database with mysql and backbone. The thing is that I can create a « user », and I can get all of them. But when I try to make :</p> <pre><code>var user = new User({id: 10}); </code></pre> <p>I always have this type of result, wichever the given id :</p> <pre><code>Object {id: "10", nom: "", age: "", prenom: ""} </code></pre> <p>But I get a response from my server:</p> <pre><code>[{"id":"10","nom":"test","prenom":"test","age":"12"}] </code></pre> <p>So, the GET request is executed, and return something not saved in the « user » variable.</p> <p>For more explanations, here is my script</p> <pre><code>// The model var User = Backbone.Model.extend({ defaults: { id:"", nom:"", age:"", prenom:"" }, url: function(){ if (this.isNew()){ return "./users.php"; } else { return "./users.php?id=" + this.id; } } }); // The collection var Users = Backbone.Collection.extend({ models:"user", url:"./users.php" }); // The view var EditUser = Backbone.View.extend({ el: ".page", render: function(options) { var that = this if (options.id) { var user = new User({id: options.id}); console.log(user.toJSON()); user.fetch({ success: function(user){ var template = _.template($('#edit-user-template').html(), {user: user}); that.$el.html(template); } }) } else { var template = _.template($('#edit-user-template').html(), {user:null}); this.$el.html(template); } }, events: { 'submit .edit-user-form' : 'saveUser', }, saveUser: function(ev){ data = $(ev.currentTarget).serializeObject(); var user = new User(); user.save(data, { success: function(user) { router.navigate('', {trigger:true}) } }); return false; } }); </code></pre> <p>And my users.php</p> <pre><code>&lt;?php $request_method = strtolower($_SERVER['REQUEST_METHOD']); switch($_SERVER['REQUEST_METHOD']){ case 'POST': save(); break; case 'GET': fetch(); break; case 'PUT': save(); break; case 'DELETE': // delete item destroy(); break; } function fetch() { $pdo=new PDO("mysql:dbname=nomade;host=localhost","",""); $sql = "SELECT * FROM users"; if (isset($_GET['id'])) $sql .= " WHERE id =".$_GET['id']; $statement=$pdo-&gt;prepare($sql); $statement-&gt;execute(); $results=$statement-&gt;fetchAll(PDO::FETCH_ASSOC); echo json_encode($results); } function save() { $pdo=new PDO("mysql:dbname=nomade;host=localhost","",""); $data = json_decode(file_get_contents('php://input')); $nom = $data-&gt;{'nom'}; $prenom = $data-&gt;{'prenom'}; $age = $data-&gt;{'age'}; $statement=$pdo-&gt;prepare("INSERT INTO users (prenom, nom, age) VALUES ('".$nom."','".$prenom."',$age)"); $statement-&gt;execute(); $results=$statement-&gt;fetchAll(PDO::FETCH_ASSOC); echo json_encode($results); } ?&gt; </code></pre> <p><strong>EDIT</strong> When I make a</p> <pre><code>var user = new User({id: options.id}); user.fetch({ success: function(user){ console.log(user.attributes[0]); // var template = _.template($('#edit-user-template').html(), {}); // that.$el.html(template); } }); </code></pre> <p>I get this :</p> <pre><code> Object {id: "5", nom: "dsfsdfqds", prenom: "qsdfqsdf", age: "12"} </code></pre> <p>Why ? </p>

    1. COLooks like your PHP is returning an array rather than just a single `User` record. Maybe `fetchObject` would be a better choice?

    3. COWhat does nothing? Your question isn't clear to me then. What is returned when you call fetchObject and return the results of that to your client?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
