我在弄清楚为什么我的承诺是不解析我希望它的方式有些问题。我使用的离子/ UI的路由。

I'm having some problems figuring out why my promise isn't resolving the way I would expect it to. I'm using Ionic/ui-routing.

我的服务：

return {
    all: function () {
        $localForage.getItem('foo').then(function (bar) {
            return bar;
        });
    }
};

当我登录的数据来安慰，我看到localForage从IndexedDB的回报对象。

When I log data to console, I see the objects that localForage returns from indexeddb.

我apps.js：

.state('tab.foo', {
    url: '/foo',
    views: {
        'tab-foo': {
            templateUrl: 'templates/tab-foo.html',
            controller: 'fooCtrl as foo'
        }
    },
    resolve: {
        getData: function (Service) {
            return Service.all();
        }
    }
})

在我的富控制器：

this.foo = getData;

当我这样做，富控制器是不确定的，任何想法，为什么？当loggig安慰我可以看到该服务由apps.js叫，我可以看到，因为我看到在控制台中的数据就得到解决。使用UI路由器我希望它不会加载该视图/控制器，直到一切都解决了。

When I do this, foo in the controller is undefined, any ideas why? When loggig to console I can see that the service is called by apps.js, I can see that it is resolved because I see the data in the console. Using ui-router I would expect it wouldn't load the view/controller until everything is resolved.

我用下面为灵感，只是没了$ Q服务。的http://odeto$c$c.com/blogs/scott/archive/2014/05/20/using-resolve-in-angularjs-routes.aspx

I used the following as inspiration, only without the $q service. http://odetocode.com/blogs/scott/archive/2014/05/20/using-resolve-in-angularjs-routes.aspx

推荐答案

有一个工作示例的。因为控制器将作为富，我们应该做的是这样的：

There is a working example. Because controller will be available as foo, we should do it like this:

控制器assignement到某些属性 myData的

The controller assignement into some property myData

.controller('fooCtrl', function($scope, getData) {
  this.myData = getData;
})

模板调用将同时包含，控制器（富），并将其属性myData的

The template call would contain both, controller (foo) and its property myData

resolved stuff:
<pre>{{foo.myData | json}}</pre>
