Meteor collection.insert 回调问题 [英] Meteor collection.insert callback issues

问题描述

根据 Meteor 文档....

According to the Meteor documentation....

collection.insert(doc, [callback])

回调函数

可选.如果存在，调用时将错误对象作为第一个参数，_id 作为第二个参数.

Optional. If present, called with an error object as the first argument and the _id as the second.

...然后再下来...

...then later down...

在服务器上，如果您不提供回调，则插入块直到数据库确认写入，或者在出现问题时抛出异常.如果您确实提供了回调，则插入立即返回.插入完成(或失败)后，将使用错误和结果参数调用回调，与方法相同.

On the server, if you don't provide a callback, then insert blocks until the database acknowledges the write, or throws an exception if something went wrong. If you do provide a callback, insert returns immediately. Once the insert completes (or fails), the callback is called with error and result arguments, same as for methods.

它是错误和 _id 还是错误和结果?我确实有 Meteor.methods 正确触发回调，但有错误，结果可用于范围.

Which is it, error and _id or error and result? I do have Meteor.methods that are firing their callbacks correctly with error, result available to the scope.

我只是无法让回调在 collection.insert(doc, [callback]) 上正常工作

I just can't get the callback to work correctly on a collection.insert(doc, [callback])

无论如何我都无法通过回调来注册任何东西?

Either way I can't get my callback to register anything?

function insertPost(args) {
  this.unblock;
  if(args) { 
    post_text = args.text.slice(0,140);
    var ts = Date.now();  
    Posts.insert({
      post: post_text,
      created: ts
    }, function(error, _id){
      // or try function(error, result) and still get nothing 
      // console.log('result: ' + result);
      console.log('error: ' + error);
      console.log('_id: ' + _id); //this._id doesn't work either
    });

  }
  return;
}

我做错了什么?我从凌晨 2 点开始编码......下午 6 点我的时区......我很模糊，所以我可能(可能)遗漏了一些很明显的东西.

What am I doing wrong? I have been up since 2 am coding...6 pm my time zone...I am blurry, so I might (probably) be missing something quite obvious.

推荐答案

这是一个错误，已在下一个版本中修复.现在，如果您向 insert 提供回调，它将使用 error 和 result 参数调用，其中 result是新文档的 ID，如果有错误，则为 null.

This was a bug, fixed in the next release. Now, if you provide a callback to insert, it will be called with error and result arguments, where result is the ID of the new document, or null if there's an error.
