嵌套子文档猫鼬...这可能吗

Question

http://mongoosejs.com/docs/subdocs.html

我正在使用上面的链接将孩子的数据“推送”给父母..

我可以将孙子的数据推送给孩子和父母吗？

代码

newPatient.EmergencyContacts.push({
     emContact_Name: emContact_Name,
     emContact_Relation: emContact_Name,
})

newPatient.EmergencyContacts.emContact_Address.push({
     emContact_AddressType: emContact_AddressType,
     emContact_AddressLine1: emContact_AddressLine1,
     emContact_AddressLine2: emContact_AddressLine2,
     emContact_City: emContact_City,
     emContact_Town: emContact_Town,
     emContact_Village: emContact_Village,
     emContact_PolicStation: emContact_PolicStation,
     emContact_District: emContact_District,
     emContact_State: emContact_State,
     emContact_PinCode: emContact_PinCode
});

newPatient.EmergencyContacts.emContact_Info.push({
     emContact_phone: emContact_phone,
     emContact_email: emContact_email
});

架构

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


var emContactInfoSchema = new Schema({
      emContact_Phone: String,
      emContact_Email: String,
});

var emContactAddressSchema = new Schema({
      emContact_AddressType: String,
      emContact_AddressLine1: String,
      emContact_AddressLine2: String,
      emContact_City: String,
      emContact_Town: String,
      emContact_Village: String,
      emContact_PolicStation: String,
      emContact_District: String,
      emContact_State: String,
      emContact_PinCode: Number,
});


var emContactSchema = new Schema({
      emContact_Name: String,
      emContact_Relation: String,
      emContact_Address: [emContactAddressSchema],
      emContact_Info: [emContactInfoSchema],
});

var patientAddressSchema = new Schema({ 
      Patient_addressType: String,
      Patient_addressLine1: String,
      Patient_addressLine2: String,
      Patient_city: String,
      Patient_town: String,
      Patient_village: String,
      Patient_policeStation: String,
      Patient_district: String,
      Patient_state: String,
      Patient_pinCode: Number,
      Patient_countryCode: String,
});

var patientContactInfoSchema = new Schema({
      Patient_phoneType: String,
      Patient_phoneNumber: String,
      Patient_emailType: String,
      Patient_email: String,
});

var patientSchema = new Schema({
    // patient  info
    Patient_UHID: { type: String, required: true, index: { unique: true } } , // Univesal Health Indentifier - Aadhar in our case
    Patient_altUHID: { type: String, required: false, trim: true, index: { unique: false } },  //  As per institution or vendor's specifications
    Patient_fName: String,
    Patient_mName: String,
    Patient_lName: String,
    Patient_dob: Date,
    Patient_age: Number,
    Patient_gender: String,
    Patient_occupation: String,

    Patient_Addresses : [patientAddressSchema],

    Patient_ContactInfo: [patientContactInfoSchema],

    Patient_insuranceStatus: String,
    Patient_allergyStatus: String,

    // Emergency Contact  info
    EmergencyContacts: [emContactSchema],
});

var patient = mongoose.model('patient', patientSchema);
module.exports = {
    Patient: patient
}

所以我想知道这是怎么可能的。任何方向都将不胜感激

Answer 1

是的，这是可能的！这就是文档数据库允许您做的事情。

根据您的架构，患者架构有一系列紧急联系人 所以newPatient.EmergencyContacts.emContact_Address 和newPatient.EmergencyContacts.emContact_Info 会给你错误，因为 newPatient.EmergencyContacts 是一个数组。

因此，您无法访问 EmergencyContacts 数组的 emContact_Address 和 emContact_Info 属性，这肯定会为您提供undefined

虽然您可以通过 EmergencyContacts 上的索引访问它：

 newPatient.EmergencyContacts[0].emContact_Address.push({
                                            emContact_AddressType: emContact_AddressType,
                                            emContact_AddressLine1: emContact_AddressLine1,
                                            emContact_AddressLine2: emContact_AddressLine2,
                                            emContact_City: emContact_City,
                                            emContact_Town: emContact_Town,
                                            emContact_Village: emContact_Village,
                                            emContact_PolicStation: emContact_PolicStation,
                                            emContact_District: emContact_District,
                                            emContact_State: emContact_State,
                                            emContact_PinCode: emContact_PinCode
                                          });
      newPatient.EmergencyContacts[0].emContact_Info.push({
                                                emContact_phone: emContact_phone,
                                                emContact_email: emContact_email

   });

希望对你有帮助！！

建议： 1）请让其他用户可以阅读您的问题。

2)您可以重构您的架构设计，请参考其他 mongoose/mongodb 函数，例如 update,$push,$elemMatch 的组合 等以减少您的代码长度

快乐编码:)

架构
