无法填充 PostgreSQL Table 在 Feathers-Sequelize 中使用一对一关联

Question

我有两个 table：Users 和 Accounts。一个用户有一个帐户，反之亦然。这是我的两个模型：

用户模型

const Sequelize = require('sequelize');
const DataTypes = Sequelize.DataTypes;

module.exports = function (app) {
  const sequelizeClient = app.get('sequelizeClient');
  const user = sequelizeClient.define('users', {

   // omitting the definition for brevity
  });


  user.associate = function (models) {

    user.hasOne(models.accounts);

    // I could get things to work when I made it a one to many
    // but that's not what I want.
    // user.hasMany(models.accounts, { foreignKey: 'user_id' });
  };

  return user;
};

账户模型

const Sequelize = require('sequelize');
const DataTypes = Sequelize.DataTypes;

module.exports = function (app) {
  const sequelizeClient = app.get('sequelizeClient');
  const account = sequelizeClient.define('accounts', {

    // omitting the definition for brevity

  });

  account.associate = function (models) {

    account.belongsTo(models.users, {foreignKey: 'user_id'});

    // I can't get groups and roles working either but that's
    // another question...
    account.belongsToMany(models.groups, {
      through: 'accountsingroups',
      foreignKey: 'accountid'
    });
    account.belongsToMany(models.roles, {
      through: 'accountsinroles',
      foreignKey: 'accountid'
    });
  };

  return account;
};

从这些模型中我得到一个 Users table 和一个 Accounts table 有一个额外的列称为 user_id.

我有一系列 before create 钩子：hashPassword、hashSecurityQuestions 和 relateAccount。前两个工作完美。第三个是我遇到问题的地方。这是我的 relateAccount 钩子：

relateAccount before create hook

module.exports = function (options = {}) {
  return function (context) {
    const AccountModel = context.app.services.accounts.Model;
    context.params.sequelize = {
      include: [{ model: AccountModel }]
    };
  };
};

通过上述设置，我可以使用 Postman 将新用户插入 Users table，但 Accounts table 仍然是空的。这是一个邮递员请求示例：

{
    "username": "doctordonna",
    "firstname": "Donna",
    "lastname": "Noble",
    "email": "besttempinchiswick@tardis.com",
    "password": "ood1!",
    "accounts":
        {
            "questiononeid": "1a3ccccb-42ff-4553-9e54-824022414f50",
            "questiononeanswer": "100 words per minute",
            "questiontwoid": "6f9b0a38-0b1f-46dd-8726-2c9ff3566686",
            "questiontwoanswer": "Adipose Industries",
            "questionthreeid": "95c7f66f-63ef-48b2-b2b4-d73d383077e8",
            "questionthreeanswer": "Vesuvius",
            "questionfourid": "ff94887b-6015-4b84-8259-4801b2b404a3",
            "questionfouranswer": "Time Vortex",
            "isapproved": true,
            "lastactivitydate": null,
            "lastlogindate": null,
            "lastpasswordchangeddate": null,
            "isonline": false,
            "islockedout": false,
            "lastlockedoutdate": null,
            "failedpasswordattemptcount": 0,
            "failedpasswordattemptwindowstart": null,
            "isdeactivated": false,
            "deactivated_at": null
        }

}

就像我上面说的，当我将我的关联更改为 一对多 时，它工作得很好，但是，我希望它是 一对一。如果我从 User Model 中删除 user.hasOne(models.accounts); 我会收到一条错误消息 error: SequelizeEagerLoadingError: accounts is not associated to users!

显然我做错了什么，我想我不理解我在 Sequelize 文档和 Feathers 文档中阅读的内容。

呃。这对我来说是一个非常愚蠢的错误。

根据我的要求，我需要将 accounts 设为单数 - account。所以我的请求应该是这样的：

{
    "username": "doctordonna",
    "firstname": "Donna",
    "lastname": "Noble",
    "email": "besttempinchiswick@tardis.com",
    "password": "ood1!",
    "account":
        {
            "questiononeid": "1a3ccccb-42ff-4553-9e54-824022414f50",
            "questiononeanswer": "100 words per minute",
            "questiontwoid": "6f9b0a38-0b1f-46dd-8726-2c9ff3566686",
            "questiontwoanswer": "Adipose Industries",
            "questionthreeid": "95c7f66f-63ef-48b2-b2b4-d73d383077e8",
            "questionthreeanswer": "Vesuvius",
            "questionfourid": "ff94887b-6015-4b84-8259-4801b2b404a3",
            "questionfouranswer": "Time Vortex",
            "isapproved": true,
            "lastactivitydate": null,
            "lastlogindate": null,
            "lastpasswordchangeddate": null,
            "isonline": false,
            "islockedout": false,
            "lastlockedoutdate": null,
            "failedpasswordattemptcount": 0,
            "failedpasswordattemptwindowstart": null,
            "isdeactivated": false,
            "deactivated_at": null
        }

}
