Ember cannot find find () method on model

Ember cannot find the methods findAll()and find()that I implemented in my Property model. Here are the errors I get:

TypeError: App.Property.findAll is not a function

and

Error: assertion failed: Expected App.Property to implement `find` for use in 'root.property' `deserialize`. Please implement the `find` method or overwrite `deserialize`.

My router is configured as follows:

App.Router = Ember.Router.extend({
    showProperty: Ember.Route.transitionTo('property'),
    root: Ember.Route.extend({
        home: Ember.Route.extend({
            route: '/',
            connectOutlets: function(router) {
                router.get('applicationController').connectOutlet('home', App.Property.findAll());
            }
        }),
        property: Ember.Route.extend({
            route: '/property/:property_id',
            connectOutlets: function(router, property) {
                router.get('applicationController').connectOutlet('property', property);
            },
        }),
    })
});

And here is my model:

App.Property = Ember.Object.extend({
    id: null,
    address: null,
    address_2: null,
    city: null,
    state: null,
    zip_code: null,
    created_at: new Date(0),
    updated_at: new Date(0),
    find: function() {
        // ...
    },
    findAll: function() {
        // ...
    }
});

What am I doing wrong? Should these methods follow the ownership model or should they go somewhere else? Should I override the method deserialize()instead of using find()? But even if I use this workaround findAll(), it still won’t work, and I still get this first error.

Thanks for any help.
