Mongoose Schema 未正确转换数据答案

【问题描述】：

所以，我有一个架构：

import mongoose from 'mongoose';
import cuid from 'cuid';
import timestamps from 'mongoose-timestamp';
import validators from 'mongoose-validators';

const Schema = mongoose.Schema;

const userSchema = new Schema({
  auth0id: { type: 'String', required: true },
  cuid: { type: 'String', default: cuid(), required: true },
  dateAdded: { type: 'Date', default: Date.now, required: true },
  email: { type: 'String', required: true, validate: validators.isEmail() },
  avatarURL: { type: 'String', required: true, validate: validators.isURL() },
  username: { type: 'String' },
  accessLevel: { type: 'Number', required: true },
  entities: [{ type: 'String', required: true }],
  preferredEntity: { type: 'String', required: true },
  tab_access: [{
    entityid: { type: 'String', required: true },
    tabs: [{ type: 'String' }],
  }],
  departments: [{
    entitytid: { type: 'String', required: true },
    deptid: { type: 'String', required: true },
  }],
});

userSchema.plugin(timestamps);

export default mongoose.model('User', userSchema);

我已经处理了一些数据：

{
    email: 'client.a@thejump.tech',
    username: 'Fred Bloggs',
    accessLevel: 5,
    entities: ['cit98hg1j000578jcffur7c6h'],
    auth0id: 'auth0|57ff79140dd70f9616b80a9d',
    avatarURL: 'https://s.gravatar.com/avatar/2dfc6cb16eea798886af841e7b1ee8ab?s=480&r=pg&d=https%3A%2F%2Fcdn.auth0.com%2Favatars%2Ffb.png',
    preferredEntity: 'cit98hg1j000578jcffur7c6h',
    departments: [{
        entityid: 'cit98hg1j000578jcffur7c6h',
        deptid: 'cit98hg1j000572jcffur7c6h'
    }],
    tabAccess: [{
        entityid: 'cit98hg1j000578jcffur7c6h',
        tabs: []
    }]
}

当我创建一个新模型时：

const mongoUser = new User(userData);

...数据不一样（注意，此时未保存）：

{
    email: 'client.a@thejump.tech',
    username: 'Fred Bloggs',
    accessLevel: 5,
    auth0id: 'auth0|57ff79140dd70f9616b80a9d',
    avatarURL: 'https://s.gravatar.com/avatar/2dfc6cb16eea798886af841e7b1ee8ab?s=480&r=pg&d=https%3A%2F%2Fcdn.auth0.com%2Favatars%2Ffb.png',
    preferredEntity: 'cit98hg1j000578jcffur7c6h',
    _id: 57 ff791473da244be87f0489,
    departments: [{
        deptid: 'cit98hg1j000572jcffur7c6h',
        _id: 57 ff791473da244be87f048a
    }],
    tab_access: [],
    entities: ['cit98hg1j000578jcffur7c6h'],
    dateAdded: Thu Oct 13 2016 13: 07: 48 GMT + 0100(BST),
    cuid: 'ciu8aq0430000k7jck2zsi5zm'
}

当它出现故障时：

擦除tab_access 数据
从部门中删除 entityid 并将其替换为 _id

有人知道为什么吗？任何帮助将不胜感激...

所以，为了清楚起见，我的路由处理程序如下所示：

export function addUser(req, res) {
  const sentUser = req.body.user;
  console.log('sentUser', sentUser);
  const newUser = {
    connection: process.env.AUTH0_DB_CONNECTION,
    password: process.env.AUTH0_DEFAULT_PASSWORD,
    username: sentUser.username,
    nickname: sentUser.username,
    email: sentUser.email,
    email_verified: false,
    app_metadata: {
      accessLevel: sentUser.accessLevel,
    },
  };
  console.log('newUser', newUser);
  management.createUser(newUser).then(user => {
    console.log('user returned on auth0 creation: ', user);
    const storedUser = { ...req.body.user };
    console.log('storedUser pre', storedUser);
    storedUser.auth0id = user.user_id;
    storedUser.avatarURL = user.picture;
    storedUser.preferredEntity = storedUser.entities[0].entityid;
    storedUser.departments = storedUser.entities.map((ent) => {
      return {
        entityid: ent.entityid,
        deptid: ent.deptid,
      };
    });
    storedUser.tabAccess = storedUser.entities.map((ent) => {
      return {
        entityid: ent.entityid,
        tabs: [],
      };
    });
    storedUser.entities = storedUser.entities.map((ent) => {
      return ent.entityid;
    });
    console.log('storedUser post', storedUser);
    const mongoUser = new User(storedUser);
    console.log('mongoUser', mongoUser);
    mongoUser.save((err, saved) => {
      if (err) {
        console.log('problem saving', err);
        return res.status(500).send(err);
      }
      return res.status(201).send({ user: saved });
    });
  }).catch(err => {
    console.log('problem saving to Auth0')
    return res.status(500).send(err);
  });
}

其中management 是 auto0 管理客户端。我重新排列数据以制作storedUser，然后通过在new User(storedUser) 中传递该数据来制作新模型并尝试保存模型。在保存模型之前，我注销了已生成的内容并看到了上述问题。

我展示的两个对象是它产生的storedUser(post) 和mongoUser。

【问题讨论】：

您可以编辑问题并添加您执行的查询以插入文档吗？
@Svabael 在这个阶段我还没有将它保存到 mongo。我做mongoUser.save() 下一个...
mongoUser.save 会将文档保存在 mongo 中
只是数组没有保存吗？

【解决方案1】：

原因是键名错误：

departments: [{
    entitytid: // change it in schema to "entityid"

注意“entitytid”的拼写。它应该是“entityid”。

第二，tab_access and tabAccess。您在架构中有 tab_access，但您在创建对象时传递了 tabAccess。

在创建“storedUser”时更正此密钥。

【讨论】：

谢谢@Sachin，对不起，这是一件很基本的事情。 :(

【解决方案2】：

我有一种感觉，但不能 100% 确定，您必须像这样定义架构：

import mongoose from 'mongoose';
import cuid from 'cuid';
import timestamps from 'mongoose-timestamp';
import validators from 'mongoose-validators';

const Schema = mongoose.Schema;

const tabAccessSchema = new Schema({
  entityid: { type: 'String', required: true },
  tabs: [{ type: 'String' }],
});

const departmentsSchema = new Schema({
  entitytid: { type: 'String', required: true },
  deptid: { type: 'String', required: true },
});

const userSchema = new Schema({
  auth0id: { type: 'String', required: true },
  cuid: { type: 'String', default: cuid(), required: true },
  dateAdded: { type: 'Date', default: Date.now, required: true },
  email: { type: 'String', required: true, validate: validators.isEmail() },
  avatarURL: { type: 'String', required: true, validate: validators.isURL() },
  username: { type: 'String' },
  accessLevel: { type: 'Number', required: true },
  entities: [{ type: 'String', required: true }],
  preferredEntity: { type: 'String', required: true },
  tab_access: [tabAccessSchema],
  departments: [departmentsSchema],
});

userSchema.plugin(timestamps);

export default mongoose.model('User', userSchema);
