流星：模板级别的条件订阅

Question

我在具有不同数据参数但使用相同发布的其他路由中重用相同的模板...

如果我进行正常的发布/订阅，数据将按预期发布。但是当我像下面那样进行有条件的发布/订阅时，我无法订阅数据。控制台日志返回空数组,,,

server/publication.js

Meteor.publish('ACStats', function(cId, uId) {
    var selectors = {cId:cId, uId:uId};
    var options = {
        fields: {qId:0}
    };
    return ACStats.find(selectors,options);
});

client/onCreated

Template.channelList.onCreated(function() {
  this.disable = new ReactiveVar('');
  if (FlowRouter.getRouteName() === 'profile') {
    var self = this;
    self.autorun(function() {
      var penName = FlowRouter.getParam('penName');
      var u = Meteor.users.findOne({slugName:penName});
      if (u) {var uId = u._id;}
      Meteor.subscribe('ACStats', null, uId);
    });
  } else{
    var self = this;
    self.autorun(function() {
      var channelName = FlowRouter.getParam('channel');
      var c = Channels.findOne({title:channelName});
      if (c) {var cId = c._id;}
      Meteor.subscribe('ACStats', cId, null);
    });
  }
});

控制台

ACStats.find().fetch() //return empty array

有人发现我的错误..??

非常感谢……

你可以发表两篇文章：

Meteor.publish ('ACStatsChannels', cId, function() {
});
Meteor.publish ('ACStatsUsers', uId, function() {
})

然后像这样订阅：

Template.channelList.onCreated(function() {
   this.disable = new ReactiveVar('');
   var self = this;
   self.autorun(function() {
      if (FlowRouter.getRouteName() === 'profile') {
          var penName = FlowRouter.getParam('penName');
          self.subscribe('ACStatsUsers', penName);
      } else {
          var channelName = FlowRouter.getParam('channel');
          self.subscribe('ACStatsChannels', channelName);
    }
  });
});
