未处理的拒绝SequelizeEagerLoadingError：用户未与userPatientAssociation关联

Question

我有两个模型，但我不知道为什么会出现以下错误：

  

Unhandled rejection SequelizeEagerLoadingError: user is not associated to userPatientAssociation

第一个模型是user，第二个模型是userPatintAssociation。

不包括第三种模型patient。我不知道我是否想念什么。

我尝试了关联，但是抛出此错误。

user模型：

const { sequelize, Sequelize, Model } = require('../config/db');
const userPatientAssociation = require('../models/userPatientAssociation');

class User extends Model { }
User.init({
  id: {
    type: Sequelize.INTEGER,
    primaryKey: true,
    autoIncrement: true,
    validate: {
      isNumeric: true,
    },
  },
  practiceId: {
    type: Sequelize.STRING,
    allowNull: true,
    field: 'practice_id',
    unique: true,
  },
  username: {
    type: Sequelize.STRING,
    allowNull: false,
    field: 'username',
    unique: true,
  },
  token: {
    type: Sequelize.STRING,
    field: 'token',
  },

  refreshToken: {
    type: Sequelize.STRING,
    field: 'refresh_token',
  },
  name: {
    type: Sequelize.STRING,
    allowNull: false,
    field: 'name',
  },
  email: {
    type: Sequelize.STRING,
    allowNull: false,
    field: 'email',
  },
  mobileNo: {
    type: Sequelize.STRING,
    allowNull: false,
    field: 'mobile_no',
  },
  password: {
    type: Sequelize.STRING,
    allowNull: false,
    field: 'password',
  },
  createdAt: {
    type: Sequelize.DATE,
    field: 'created_at',
  },
},
  {
    sequelize,
    modelName: 'user',

  });

module.exports = User;

association模型：

const user = require('../models/user');
const patient = require('../models/patient');
const { sequelize, Sequelize, Model } = require('../config/db');

class UserPatientAssociation extends Model {}
UserPatientAssociation.init({
  id: {
    type: Sequelize.INTEGER,
    primaryKey: true,
    autoIncrement: true,
    validate: {
      isNumeric: true,
    },
  },
  userId: {
    type: Sequelize.INTEGER,
    field: 'user_id',
    validate: {
      isNumeric: true,
    },
    references: {
      model: user,
      key: 'id',
    },

  },
  previousUserId: {
    type: Sequelize.INTEGER,
    field: 'previous_user_id',
    validate: {
      isNumeric: true,
    },
    references: {
      model: user,
      key: 'id',
    },
  },
  patientId: {
    type: Sequelize.INTEGER,
    field: 'patient_id',
    references: {
      model: patient,
      key: 'id',
    },
  },
}, 
{
  sequelize,
  modelName: 'userPatientAssociation',
});

module.exports = UserPatientAssociation;
