How to prevent Backbone.Marionette from rendering a view if it's model hasn't been fetched?

Question

In my backbone.Marionette application I have a Model that requires an Id attribute to construct it\'s url. I therefore create the model by passing it an Id, add it to a view

Answer 1

Both answers above work.
Here's yet another way which I prefer to use (feels more backboney).

Bind the view directly to the model
When the model is done being fetched, the function you specify will run. This can be done with models or collections.

var Model = Backbone.Model.extend({});
var model = new Model();
model.fetch();

var View = Marionette.ItemView.extend({
    model:model,
    initialize: function(){
        this.model.bind("sync", this.render, this);// this.render can be replaced
    }                                              // with your own function
});                               

app.region.show(new View);                                           

This also enables you to fetch whenever you want.
