解析MongoDB对象（使用Mongoose）时，为什么无法获得item元素？

Question

IndexedTweets.find(searchParameters, function(err, indexedTweetsResults) {
  var chunkSize, count, resultArray, size;
  if (err != null) {
    return console.log("Error!");
  } else {
    size = indexedTweetsResults.length;
    count = 0;
    chunkSize = 100;
    resultArray = [];
    indexedTweetsResults.forEach(function(tweet) {
      console.log(tweet.user);
    });
  }
});

That's my code. My result looks like:

{ text: 'stuff',
  user: 
   { display_name: '...',
     screen_name: '...'},
}

So why can't I get tweet.user ? It just returns undefined .

If you are just getting back a string of JSON from mongo, you'll need to call JSON.parse(). If that's not the case then you should provide more code because it's not clear what the issue is.
