是否有可能在$ rootScope变量使用getReactively？ [英] is it possible to use getReactively on $rootScope variables?

问题描述

我有，我想因此如果用户是注销和登录不同的用户，在UI用户的比分改变为更新基于用户界面的情况。我想过做它的方式是看 $ rootScope.currentUser 。

I have a case that I want to update the ui based on the user so if a user was log-out and log-in as different user, a score of the user in the ui is changed. The way I thought about doing it is by looking at $rootScope.currentUser.

这是我的测试中好像有某种访问$ rootScope，但它是没有得到用户的改变而更新（除非我有我的code错误）。这里是有关code：

from my testing it seems like there is some kind of access to the $rootScope, but it is not getting updated on user change (unless I have a bug in my code). here is the relevant code:

$meteor.autorun($scope, function() {
            if (null !== $rootScope.currentUser) {
                $scope.userForScore = $scope.$meteorObject(Userinfo, {user_id: $scope.getReactively('currentUser')._id});//$rootScope.currentUser._id
            }
        });

    $scope.userScore = function(){
        if ($scope.userForScore === undefined || $scope.userForScore.score === undefined) {
            return 1;
        }
        return $scope.userForScore.score;
    };

用户信息 - 我是在服务器上创建的集合

Userinfo - is a collection I created in the server.

推荐答案

是的，它是可能的，它的工作原理完全一样，你做到了。

Yes it is possible and it works exactly like you did it.

您的问题是无关getReactively，我创建了一个拉请求您的回购来解决它：

Your problem was unrelated to getReactively, I've created a pull request to your repo to fix it: https://github.com/Urigo/angular-meteor/issues/415#issuecomment-113925910
