我们可以将游标设置为会话变量吗？ [英] Can we set cursor as a session variable?

问题描述

我试图将光标设置为会话变量，看起来它不起作用。

任何人都有这个想法？

我的代码：

  Meteor.call（'apiresult'，函数（e，结果）
 {
 console.log（result）; 
 Session.set（object，result）
}）; 
 
 //获取变量
 var abc = Session.get（object）; 
返回abc.skimlinksProductAPI.numFound; 
  

看起来无法正常工作

解决方案

游标可以实际存储在 Session ...中。打开（ sort ， fields 等）而不是对象。

I tried to set a cursor as a session variable looks like it is not working.

Anyone has idea about it ??

My Code:

 Meteor.call('apiresult',function(e,result)
    {                                               
    console.log(result);
    Session.set("object",result)                                                                                                        
    }); 

//getting variable
 var abc=Session.get("object");
return abc.skimlinksProductAPI.numFound;        

looks like it's not working

解决方案

Cursors can actually be stored in Session... sometimes. open the leaderboard app and try this in the browser console:

> Session.set('mycursor', Players.find());
undefined
> Session.get('mycursor')
LocalCollection.Cursor {collection: LocalCollection, selector_f: function, sort_f: null, skip: undefined, limit: undefined…}
> Session.get('mycursor').fetch()
[Object, Object, Object, Object, Object]

Now download the code of the leaderboard example app, use the latest Meteor, and do the same thing in the browser console. You might get:

The moral of the story seems to be, don't store cursors in session variables. Store the Minimongo selector and options (sort, fields etc.) instead as objects.
