如何在emberjs的嵌套控制器上执行“需求”？

Question

我有以下路由器：

this.resource('foo', {path: '/foo'}, function() {
    this.resource('foo.bar', {path: '/bar'}, function() {
        this.route('wat', {path: '/wat'});
    });
});

我的FooBarWatController是一个单身人士，我需要访问FooBarController的模型。 needs FooBarWatController对FooBarController的访问权限是什么意思？

FooBarWatContoller = Ember.ObjectController.extend({
    needs: ['?'],
    action: {
        something: function() {
            console.log(this.get('controllers.?.model').get('id'));
        }
    }
});

Answer 1

FooBarWatContoller = Ember.ObjectController.extend({
    needs: ['foo/bar'],
    action: {
        something: function() {
            console.log(this.get('controllers.foo/bar.model').get('id'));
        }
    }
});
