This is MVC, right?

Where do models go?

There's no set place for models, so you can put them whereever you want. For example, you can embed logic in your controllers (/app/js/controllers.js) or, even better, create services as explained in the Angular docs here. Services are in /app/js/services.js

Let's make a service.

I like to see things fail first, so we'll start from the other end.

Bind the view

In /app/partials/partial1.html, add

card: {{ card | json }}}

This will print out the card as JSON. Refresh and nothing happens. Cool, I guess. This is because the card object doesn't exist in $scope for this controller.

Update the controller

We need to add card to the $scope. In the MyCtrl1 controller, add

$scope.card = { fake: 'card' };

Refresh to see this placeholder appear in our view.

Inject a service

We could create our "model" here, but, as described above, we're going to opt for using a service. This way, we can use it all over the place, not just in this controller.

• Add 'cardService' to the list of myApp.controllers dependencies.
• Add cardService to the arguments in the function.
• Swap { face: 'card' } out for cardService.

You should end up with something like this.

  .controller('MyCtrl1', [
    // dependencies
    '$scope',
    'cardService', 
    
    function ($scope, cardService) {
      $scope.card = cardService;
    }
  ])

Refresh and you'll see Angular complain.

Unknown provider: cardServiceProvider <- cardService

Create the service

In /app/js/services.js, add a definition for our service. We do this with the service method. Yeah, it's not what you would normally think of as a service, it's just what Angular uses to define dependencies.

.service(
  // service name
  'cardService',

  // provider function, responsible for creating instances
  function () {
    return { isCard: true };
  }
)

Now when we view our page, we see the data from our service, injected into our model, and plugged into the view.

How do I create useful models - constructors, prototypes, etc?
