升级到 angularfire 1.2 时，获取 a.ref 不是函数错误

问题描述

以下代码库用于处理 firebase 2.3.1 和 Angularfire 1.1.3

Following codebase used to work with firebase 2.3.1 and Angularfire 1.1.3

Var fb = new firebase("https://database name.firebaseio.com");

var fbObj = $firebaseObject(fb.child("users/" + userId));

我升级到了 firebase3.0 和 Angularfire 1.2.

I upgraded to firebase3.0 and Angularfire 1.2.

结果，上面的代码是这样修改的:

As a result, here is how the above code got modified:

var config = {/* ...  */};
firebase.initializeApp(config);
var fb = firebase.database().ref();

var fbObj = $firebaseObject(fb.child("users/" + userId))

然而上面的代码在实例化fbObj时抛出了错误，例如a.ref is not a function.

The above code however threw error such as a.ref is not a function when instantiating fbObj.

请提出建议.

推荐答案

你不应该将你的 firebase 升级到 3.0，因为 AngularFire 升级到 3.0 还没有完成.

you should not upgrade your firebase to 3.0 because AngularFire upgrade to 3.0 has not been completed.
