Meteor 发布未定义或发布函数只能返回一个游标或游标数组

问题描述

当我使用 findOne 时，我的 Meteor 发布有一些有线问题，但它可以工作，但使用 find 却没有，而使用 findOne 时出现光标错误.

Having some wired issues with my Meteor publish when I have findOne it works but with find it does not and with findOne I get a cursor error.

这是我的代码

Meteor.publish('organizations', function() {
    var user = Meteor.users.findOne(this.userId);
    if(!user) return '';
     var debugTest = Organizations.findOne(user.organizationId);
      console.log(debugTest._id);
    //return Organizations.findOne({_id: user.organizationId});
});

为此我未定义

如果我执行以下操作

Meteor.publish('organizations', function() {
  var user = Meteor.users.findOne(this.userId);
  if(!user) return '';
  console.log(user.organizationId);
  var debugTest = Organizations.findOne(user.organizationId);
  console.log(debugTest._id);
  //return Organizations.findOne({_id: user.organizationId});
});

我取回了两个 ID，但返回时出现以下错误

I get back both ID's but with the return I get the following error

错误来自子 KLnQphHTXmQcjEi2D 的异常错误:发布函数只能返回一个游标或游标数组

The errorException from sub KLnQphHTXmQcjEi2D Error: Publish function can only return a Cursor or an array of Cursors

推荐答案

findOne 不返回 Mongo 游标.它返回一个 Mongo 文档.如果您希望它起作用，请尝试更改为使用 return Organizations.find({_id: user.organizationId}); 代替.这将返回一个单独的文档游标，这是发布调用所期望的.

findOne does not return a Mongo cursor. It returns a Mongo document. If you want this to work, try changing to using return Organizations.find({_id: user.organizationId}); instead. That will return a single document cursor which is what the publish call expects.
