Tips on extracting attributes from a Backbone model utilizing the Django authentication backend API

In a current project, I am utilizing the Django auth backend, Django REST framework API, and Backbone.

var User = Backbone.Model.extend({
  urlRoot: host + 'api/users/'
});

// django auth response
var isAuthenticated = {{ request.user.is_authenticated|yesno:"true,false" }};
if (isAuthenticated){
  var userID = {{ request.user.id }}; // django user id
  console.log(userID); // verifying value
  var currentUser = new User({id: userID});
  currentUser.fetch();
  var username = currentUser.get('username');
  console.log(currentUser); // verifying value

Result displayed in console.log(currentUser)

attributes: Object
    email: "y****@*****m"
    first_name: ""
    id: 1
    is_staff: true
    last_name: ""
    url: "http://127.0.0.1:8000/api/users/1/"
    username: "yorsant"

How do you interpret the attributes:Object?

Answer №1

According to the insights shared by Eric, the fetch function operates asynchronously.

The reason you can see the data in the console is because when you explored the object, it allowed enough time for the API request and response cycle to be completed.

In the Chrome developer tools console, a reference to the logged object is retained. When the user interacts with it (like collapsing the object with a click), an exclamation mark ! appears next to the object indicating that:

The value below was evaluated just now.

The Model fetch function in Backbone provides various options such as a success callback that can be passed.

currentUser.fetch({
    success: function() {
        console.log("username:", currentUser.get('username'));
    }
});

Understanding this, within a Backbone view, you have the option of utilizing Backbone's events to ascertain when the attributes are ready for use.

var View = Backbone.View.extend({
    initialize: function() {
        this.listenTo(this.model, 'sync', this.render);
        this.model.fetch();
    },

    // This method is invoked when the model's sync event is triggered, signifying
    // that the model's attributes are available.
    render: function() {
        this.$el.html(this.template(this.model.toJSON()));
        return this;
    }
});

"sync"

(model_or_collection, response, options)
— triggers when a model or collection has successfully synchronized with the server.
