如何撇清angularFire绑定的对象？ [英] How to disassociate angularFire bound object?

问题描述

我用我的应用程序AngularJS和火力地堡。我绑定的对象是在同步的火力点：

I am using AngularJS and FireBase in my application. I bound an object to be in sync with FireBase:

$scope.winnerPromise = angularFire(travelBidsFirebaseRef + "/user/" + $scope.auction.winnerUserId, $scope, 'winner', {});

现在我想撇清$ scope.winner，这意味着我希望它在火力地堡DB保持安全的，但我不希望我的范围变量'赢家'用它了同步。我怎么做？我看到angularfire.js解除关联（）finction但我不知道怎样才能使用它。任何想法？

Now I want to disassociate $scope.winner, meaning I want it to stay safe in the FireBase DB, but I don't want my scope variable 'winner' to be synchronized with it anymore. How do I do that? I saw disassociate() finction in angularfire.js but I don't see how I can use it. Any ideas?

推荐答案

解除关联函数传递给你当的承诺得到解决。我想如下方式使用它

The disassociate function is passed to you when the promise is resolved. I'd use it as follows:

var ref = travelBidsFirebaseRef.child("user/" + $scope.auction.winnerUserId);
var promise = angularFire(ref, $scope, "winner", {});
promise.then(function(disassociate) {
  // Do some work...
  disassociate(); // Don't synchronize $scope.winner anymore.
});

希望这有助于！
