流星：启动和数据加载

Question

Because findOne is returning undefined for some data, I tried to set up a Session variable like this:

Meteor.startup(function(){
  Session.set('drawingsLoaded', false);
})

Deps.autorun(function(){
  Meteor.subscribe('allDrawings', function(){  
    Session.set('drawingsLoaded', true);    
    console.log(Session.get('drawingsLoaded'))
  });

Console logs true. But when I interactively enter

Session.get('drawingsLoaded')

it's returning false.

I have no idea why and so my data is not displaying probably because of this. I am very confused why this is returning false even though I did not set drawingsLoaded anywhere else other than startup

如果这是您的实际代码，则可能在传递给Meteor.startup的回调之前调用传递给订阅的ready callback？
