Javascript 使用Angular Meteor、PublishComposite和Collection助手的无限摘要循环错误

我正试图通过以下两个软件包获得angular meteor的相关数据：

流星收集助手： 流星发布组合：

我的设置如下所示：

// persistent instance cache
this.teamsMap = [];

this.helpers({
    teams() {
        const members = People.find({}).fetch();

        members.forEach(member => {
            this.teamsMap[member._id] = member.teams.map(team => Teams.findOne(team));
        });
    }
});

model/groups.js

server/groups.js

client/matches/controller/scores.ng.js

client/matches/views/scores.ng.html

发布/订阅部分工作正常，我可以通过控制台获取所有组和相关用户，但只要添加“user in group.usersByScore（）”，我就会发现很多错误：

感谢您的帮助。

发生这种情况的原因是

usersByScore（）

每次调用函数时都返回一个新的对象实例。因此，摘要循环认为对象在不断更新，并放弃以避免被卡住

目前，我一直在解决同一个问题，所以我还不知道如何解决它

---

编辑：对这个问题进行了相当广泛的研究后，我不得不得出结论，如果不对角流星进行重大修改，这是不可能实现的。

我也有类似的问题。ng repeat循环中集合文档的集合帮助器调用导致摘要循环

在我的情况下，我收集了多个团队中每个人的人员（人员文档上的团队ID数组）

在对这个问题进行调查后，我得出了与@mpkorstanje类似的结论。最后，我发现自己在客户端应用程序中实现了一个AngularMeteor助手，并放弃了本例中的收集助手

我的angular meteor助手实现如下所示：

// persistent instance cache
this.teamsMap = [];

this.helpers({
    teams() {
        const members = People.find({}).fetch();

        members.forEach(member => {
            this.teamsMap[member._id] = member.teams.map(team => Teams.findOne(team));
        });
    }
});

以及控制器功能，用于访问视图中人员的团队：

getTeams(member) {
    return this.teamsMap[member._id];
}

通过这个实现，反应性和视图绑定可以按预期工作，我没有得到摘要循环。不幸的是，它有一种令人讨厌的味道。希望它能帮助别人解决问题

angular.module('tippo').config(['$urlRouterProvider', '$stateProvider', '$locationProvider',
    function($urlRouterProvider, $stateProvider, $locationProvider){
        $locationProvider.html5Mode(true);

        $stateProvider.state('scores', {
            url: '/scores',
            templateUrl: 'client/matches/views/scores.ng.html',
            controller: 'ScoresController',
            resolve: {
                'subscribe': ['$meteor', function($meteor) {
                    return $meteor.subscribe('groupsWithUsers');
                }],
                "currentUser": ["$meteor", function($meteor){
                    return $meteor.requireUser();
                }]
            }
        });
    }
]);
