警报已插入但未显示

Question

我正在处理一个未读的消息计数器，并收集警报和消息。

现在问题是控制台日志显示警报附加到消息，但计数器没有显示。在console3e中键入Alerts.find().count();得0。

模板计数器+点击清除提醒

//helper 
   alertCount: function(){
      return Alerts.find({ userId: Meteor.userId(), read: false }).count();
   }
//event 
   'click .enterRoom': function() {
      Meteor.call('markAlertsAsRead', { roomId: this._id }); 
   }

提交消息时附加提醒

  'submit form': function(e, template) {  
      e.preventDefault();
      var message = template.find('input').value;  
      var roomId = this._id; 
      var messageId = Messages.insert ({ 
         roomId    : Router.current().params._id, 
         msg       : message,
         userId    : Meteor.user()._id,
      });
      template.find('input').value = '';
      createMessageAlert(messageId, roomId, message);

      var insertedMessage = Messages.findOne(messageId);
      console.log(insertedMessage + messageId); //logs msg + alert 
   }

alert.js集合中的

Meteor.methods({
   markAlertsAsRead: function(options){ 
      check(options, Object);
      Alerts.update({ roomId: options.roomId }, { $set:{ read: true } }, { multi: true });
   } 
});

createMessageAlert = function(messageId, roomId, message){
      if ( message.user !== Meteor.userId() ){     
         Alerts.insert({
            userId        : message.userId,
            roomId        : Router.current().params._id,
            messageId     : messageId, 
            read          : false
         }, function(error, result){
               if( error ) 
                    console.log( error );
               if( result ) 
                    console.log( 'alert attached, alertId: ' + result );
                    //returns an alertId in my case
         });
         console.log('alert#: ' + Alerts.find().count()); //returns 0
      }
};
