我有这个Mongoose Schema.

var mongoose = require ('mongoose')
  , dev      = require ('../db').dev ();

var schema = new mongoose.Schema ({
  date: {
    type: Date,
    default: Date.now
  },
  company: {
    type: mongoose.Schema.Types.ObjectId,
    ref: 'Company'
  },
  questionnaire: {
    type: mongoose.Schema.Types.ObjectId,
    ref: 'Questionnaire'
  }
});

module.exports = dev.model ('Survey', schema);

我只想查找具有特定公司ID的调查.我怎么做？我试过(使用我的Express处理程序):

app.get ('/survey', function (req, res) {
  Survey.find ({ company: req.query.company }).populate ('questionnaire').exec (function (err, surveys) {
    return res.json (surveys);
  });
});
