Question

为什么在查询内部查询更改时通知不会触发？当我把这个代码放在一个帮助器中时，它只能用于那个助手模板。

Tracker.autorun(function () {
  Meteor.subscribe('theNotificationStatus');
  Meteor.subscribe('theNotificationSubscriptions');

  var currentUserID = Meteor.userId();
  var usersEventIds =  Subscriptions.find({userID: currentUserID}, {"eventID": 1});
  var userCategorys = Subscriptions.find({userID: currentUserID}, {"category": 1});
  var arrayEvents = [];
  var arrayCategory =[];

  usersEventIds.forEach(function (collection) {
    arrayEvents.push(collection.eventID);
  });

  userCategorys.forEach(function (collection) {
    arrayCategory.push(collection.category);
  });


  //All of the status's the user should be notified for based on what eventID and categories he/she is subscribed to.
  var query = Status.find({ $and: [ { eventID: { $in: arrayEvents  } } , { category: { $in: arrayCategory } }, { createdBy: { $ne: currentUserID } } ] }, {sort: {date: -1} } );

  var handle = query.observe({
    added: function (id, fields) {
      sAlert.success('New Notifications', {timeout: '6000'});
    },
  });

  // After five seconds, stop keeping the count.
  setTimeout(function () {handle.stop();}, 5000);

});

如果您使用React，将这些日志放入String user = getArguments().getString("user");或Template.someTemplate.onCreated时会得到什么日志？

componentWillMount
