meteor：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出版物的其他路径中重复使用相同模板...

如果我正常 pub/sub，数据将按预期发布。但是当我像下面这样有条件地 pub/sub 时，我无法订阅数据。控制台日志 return 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....

您可以发表两次：

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

然后这样订阅：

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);
    }
  });
});
