流星 collections 刷新时不加载

meteor collections don't load on refresh

出于某种奇怪的原因,我根本无法在本地重现,meteor 在刷新页面时不会加载任何 collections,但它们在状态与状态之间的转换中工作得很好。我已经向 collection 添加了一个 onready 和 onerror 函数,但它们实际上都没有 运行 刷新。

this previous so question seems to solve the problem. 我无法像他那样解决问题,因为显然 angular 的 ui 路由器不尊重等待和数据。因此,link 对我没有多大用处。几天来我一直在努力解决这个问题,但我一无所获。在此先感谢您的帮助。

我确定我在这里发布的代码太多了,但我宁愿是全面的。

collections/meetings.js

Meetings = new Mongo.Collection('meetings');

Meetings.allow({
  insert: function (userId, doc) {
    return userId && doc.owner === userId;
  },
  update: function (userId, doc, fields, modifier) {
    return userId && doc.owner === userId;
  },
  remove: function (userId, doc) {
    return userId && doc.owner === userId;
  }
});

Meetings.before.insert(function(userId, doc) {
  doc.created_at = new Date().getTime();
  doc.owner = userId;
  doc.private = true;
});

Meetings.before.update(function(userId, doc, fieldNames, modifier, options) {
  modifier.$set = modifier.$set || {};
  modifier.$set.updatedAt = new Date().getTime();
});

publishes/meetings.js

Meteor.publish("meetings", function () {
  return Meetings.find({});
});

meetingController.js

  function meetingCtrl($scope, $location, $reactive, $http) {
    const vm = this;
    vm.me = Meteor.userId();
    vm.lastWeek = moment().add(-1, 'weeks').unix();

    $reactive(vm).attach($scope);

    vm.subscribe('meetings', () => [], {
      onReady: function () { console.log("onReady", arguments); },
      onError: function () { console.log("onError", arguments); }
    });

    vm.helpers({
      meetings: () => Meetings.find(
        {$and: [
          {created_at: {$gte: this.getReactively('lastWeek')}},
          {owner: this.getReactively('me')}
        ]})
    });

index.ng.html

  <div ng-repeat="meeting in vm.meetings" class="meeting">
    {{meeting.name}}
  </div>

router.js

.state('meetings', {
  url: '/meetings',
  controller: 'meetingCtrl',
  controllerAs: 'vm',
  templateUrl: baseUrl + 'meetings/' + template,
  resolve: {
    user: ($auth) => {
      return $auth.requireUser();
    }
  }
})

原来你绝对可以通过路由器解决这个问题,使用以下方法:

    user: ($auth) => {
        ...
    },
    meetings: ['$q', ($q) => {
      var deferred = $q.defer();

      Meteor.subscribe('meetings', {
        onReady: deferred.resolve,
        onStop: deferred.reject
      });

      return deferred.promise;
    }]
