小编Set*_*upX的帖子

按照http://getbootstrap.com/components/#media上的说明,我复制了代码:

<div class="container">
<div class="media">
      <a class="media-left media-bottom" href="#">

      <div class="media-body">
        <h4 class="media-heading">Bottom aligned media</h4>

为什么mongoose在这个剧本中根本不起作用

  var child_process = require('child_process');
  // Load required packages
  child_process.exec("mongo test --eval 'db.users.drop();'", function(err){
  var mongoose = require('mongoose');

  console.log(mongoose.version);
  mongoose.connect('mongodb://localhost:27017/test');
  // Define our user schema

  var json = {};
  json.phone = { type: String, required: true, unique: true};
  var UserSchema = new mongoose.Schema(json);
  var Model = mongoose.model('user', UserSchema);

  var jp = new Model({ phone: "123456"});
  mongoose.connection.on('open', function(){
    console.log(jp);
    jp.save(function(err){
      console.log(err);
      var jp2 = new Model({ phone: "123456"});
      console.log(jp2);
      jp2.save(function(err){
        console.log(err);
        process.exit();
      });
    })
  });
});

我很困惑,结果就像

3.8.20
{ phone: '123456', …
