Question

我（尝试）使用mongoose，express和node构建API系统。现在我有两个模式：用户和事件。

用户架构：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var userSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true,
    unique: true
  },
  profileImage: {
    data: Buffer,
    contentType: String
  },
  isAdmin: {
    type: Boolean,
    'default': false
  },
  bio: {
    type: String,
    'default': ''
  }
});

mongoose.model('User', userSchema);

事件架构：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var userSchema = mongoose.model('User').schema;

var eventSchema = new Schema({
  title: {
    type: String,
    required: true
  },
  date: {
    type: Date,
    'default': Date.now
  },
  place: {
    type: String,
    required: true
  },
  distance: {
    type: String,
    'default': '-1'
  },
  eventType: {
    type: Number,
    'default': 2 /* 0 = Asfalto, 1 = Trail, 2 = Otros */
  },
  attenders: [userSchema],
  comment: {
    type: String,
    'default': ''
  }
});

mongoose.model('Event', eventSchema);

然后我定义了一个控制器来管理某个端点上的POST请求。在我的控制器上，我只检查事件请求中的“标题”和“位置”字段，如下所示：

if (!req.body.title) {
    response.sendJSON(res, 400, null, {"message": "title param is needed"});
    return;
  }

  if (!req.body.place) {
    response.sendJSON(res, 400, null, {"message": "place param is needed"});
    return;
  }

  Events
    .create({
      title: req.body.title,      
      place: req.body.place
    }, function(err, event) {
      if (err) {
        response.sendJSON(res, 400, null, err);
      } else {
        response.sendJSON(res, 201, event, null);
      }
    });
};

所以我发送请求，使用'标题'：'示例标题'，'地点'：'西班牙'作为身体参数。

第一个请求成功创建了新事件，但是nexts请求显示了这个错误：

"status": 400,
    "error": {
        "code": 11000,
        "index": 0,
        "errmsg": "E11000 duplicate key error index: som-passatge.events.$attenders.email_1 dup key: { : null }",
        "op": {
            "title": "Título de evento 22",
            "place": "Valencia",
            "_id": "56cc905d496141587dc47caf",
            "comment": "",
            "attenders": [],
            "eventType": 2,
            "distance": "-1",
            "date": "2016-02-23T17:01:17.650Z",
            "__v": 0
        }
    },
    "response": null

我不知道我做错了什么......

使用Mongoose的MongoDB：E11000重复键错误索引
