Javascript 结合流星收集

这个问题与此有关

简言之，我正在尝试构建一个新闻提要，很像Facebook的无限滚动功能。在这个新闻提要中，我想根据发布的日期显示来自不同集合的帖子。我有一个部分正常工作的代码（见下文），但问题是，因为我已将

限制设置为3，刷新后，网站将为每个收藏提供3篇文章，而不是任何收藏的3篇最新文章

我想这是因为我出版这些收藏的方式，或者是我订阅它们的方式。代码如下：

publish.js

Meteor.publish('newsfeed', function(limit){
  data = [
    Status.find({}, {limit:limit, sort: {createdAt:-1}}),
    Story.find({}, {limit:limit, sort: {createdAt:-1}}),
    Lesson.find({}, {limit:limit, sort: {createdAt:-1}}),
    Images.find(),
    Documents.find()
  ];
  return data;
});

newsfeed_increment = 3;
Session.setDefault('newsfeedLimit', newsfeed_increment);
Deps.autorun(function(){
  Meteor.subscribe('newsfeed', Session.get('newsfeedLimit'));
});

Template.statusBox.helpers({
  //Merging few collections into one template helper: https://stackoverflow.com/questions/21296712/merging-collections-in-meteor
  newsfeedList: function(){
    var hza = Status.find().fetch()
      .concat(Story.find().fetch())
      .concat(Lesson.find().fetch());
      var sortie = _.sortBy(hza, function(doc) { return doc.createdAt; });
      var ietros = sortie.reverse();
      return ietros;
...
});

Template.statusBox.helpers({
  newsfeedList: function(){
    var limit = Session.get('newsfeedLimit');
    var hza = Status.find({limit:limit, sort: {createdAt:-1}).fetch()
      .concat(Story.find({limit:limit, sort: {createdAt:-1}).fetch())
      .concat(Lesson.find({limit:limit, sort: {createdAt:-1}).fetch());
    var sortie = _.sortBy(hza, function(doc) { return doc.createdAt; });
    var ietros = sortie.reverse();
   return ietros;
   ...
});

statusBox.js

Meteor.publish('newsfeed', function(limit){
  data = [
    Status.find({}, {limit:limit, sort: {createdAt:-1}}),
    Story.find({}, {limit:limit, sort: {createdAt:-1}}),
    Lesson.find({}, {limit:limit, sort: {createdAt:-1}}),
    Images.find(),
    Documents.find()
  ];
  return data;
});

newsfeed_increment = 3;
Session.setDefault('newsfeedLimit', newsfeed_increment);
Deps.autorun(function(){
  Meteor.subscribe('newsfeed', Session.get('newsfeedLimit'));
});

Template.statusBox.helpers({
  //Merging few collections into one template helper: https://stackoverflow.com/questions/21296712/merging-collections-in-meteor
  newsfeedList: function(){
    var hza = Status.find().fetch()
      .concat(Story.find().fetch())
      .concat(Lesson.find().fetch());
      var sortie = _.sortBy(hza, function(doc) { return doc.createdAt; });
      var ietros = sortie.reverse();
      return ietros;
...
});

Template.statusBox.helpers({
  newsfeedList: function(){
    var limit = Session.get('newsfeedLimit');
    var hza = Status.find({limit:limit, sort: {createdAt:-1}).fetch()
      .concat(Story.find({limit:limit, sort: {createdAt:-1}).fetch())
      .concat(Lesson.find({limit:limit, sort: {createdAt:-1}).fetch());
    var sortie = _.sortBy(hza, function(doc) { return doc.createdAt; });
    var ietros = sortie.reverse();
   return ietros;
   ...
});

有什么想法吗？
您也应该在客户端（即，在

statusBox.js

Meteor.publish('newsfeed', function(limit){
  data = [
    Status.find({}, {limit:limit, sort: {createdAt:-1}}),
    Story.find({}, {limit:limit, sort: {createdAt:-1}}),
    Lesson.find({}, {limit:limit, sort: {createdAt:-1}}),
    Images.find(),
    Documents.find()
  ];
  return data;
});

newsfeed_increment = 3;
Session.setDefault('newsfeedLimit', newsfeed_increment);
Deps.autorun(function(){
  Meteor.subscribe('newsfeed', Session.get('newsfeedLimit'));
});

Template.statusBox.helpers({
  //Merging few collections into one template helper: https://stackoverflow.com/questions/21296712/merging-collections-in-meteor
  newsfeedList: function(){
    var hza = Status.find().fetch()
      .concat(Story.find().fetch())
      .concat(Lesson.find().fetch());
      var sortie = _.sortBy(hza, function(doc) { return doc.createdAt; });
      var ietros = sortie.reverse();
      return ietros;
...
});

Template.statusBox.helpers({
  newsfeedList: function(){
    var limit = Session.get('newsfeedLimit');
    var hza = Status.find({limit:limit, sort: {createdAt:-1}).fetch()
      .concat(Story.find({limit:limit, sort: {createdAt:-1}).fetch())
      .concat(Lesson.find({limit:limit, sort: {createdAt:-1}).fetch());
    var sortie = _.sortBy(hza, function(doc) { return doc.createdAt; });
    var ietros = sortie.reverse();
   return ietros;
   ...
});
