问题描述
const EventSchema = new Schema({ dates: [Number], reason: {type: String,required: true }, userId: Schema.Types.ObjectId, type: {type: String,required: true }});
const CalendarSchema = new Schema({ date: {type: Number,index: { unique: true} }, events: [EventSchema]});
在mongoose张这样嵌入子文档应该是没问题的吧？可我在插入子文档的时候报错了
.post(({ body }, res, next) => { const event = new Event(body); event.save().then(savedEvent => { let promises = []; for (date of body.dates) {promises.push(Calendar.update({date}, { $push: savedEvent._doc})); } return Promise.all(promises);}).then(() => res.end()).catch(next);})
错误:The field ’_id’ must be an array but is of type OID in document {_id: ObjectId(’57c5a02c8890a02814771df1’)}
是我哪里写错了吗？
问题解答
回答1：写法是不是不太对啊,文档上是这样用的var personSchema = Schema({ _id : Number, name : String, age : Number, stories : [{ type: Schema.Types.ObjectId, ref: ’Story’ }]});var storySchema = Schema({ _creator : { type: Number, ref: ’Person’ }, title : String, fans : [{ type: Number, ref: ’Person’ }]});
