Question

迁移模型后，我将启动节点开发服务器。我怎么会遇到两个错误：

在我的模型中声明多个ENUM数据类型时出现TypeError和And Error。

我尝试更改其他ENUM字段的类型，如果只有一个ENUM字段，则它起作用，但如果有多个，则不起作用。我不知道如何处理Sequelize camelize()库中sequelize实用程序功能的类型错误。

A:\Portal_project\customer-portal\Server\node_modules\sequelize\lib\utils.js:94
  return str.trim().replace(/[-_\s]+(.)?/g, (match, c) => c.toUpperCase());

TypeError：无法读取未定义的属性“ toUpperCase” 在str.trim.replace（A：\ Portal_project \ customer-portal \ Server \ node_modules \ sequelize \ lib \ utils.js：94：61）在String.replace（）在Object.camelize（A：\ Portal_project \ customer-portal \ Server \ node_modules \ sequelize \ lib \ utils.js：94：21）在新的HasOne（A：\ Portal_project \ customer-portal \ Server \ node_modules \ sequelize \ lib \ associations \ has-one.js：43：31）在功能。（A：\ Portal_project \ customer-portal \ Server \ node_modules \ sequelize \ lib \ associations \ mixin.js：105：25）在Function.Employee.associate（A：\ Portal_project \ customer-portal \ Server \ db \ models \ employee.js：58：14）在Object.keys.forEach.modelName（A：\ Portal_project \ customer-portal \ Server \ db \ models \ index.js：30：19）在Array.forEach（）在对象。（A：\ Portal_project \ customer-portal \ Server \ db \ models \ index.js：28：17）在Module._compile（内部/模块/cjs/loader.js:689:30）在Object.Module._extensions..js（内部/模块/cjs/loader.js:700:10）在Module.load（internal / modules / cjs / loader.js：599：32）在tryModuleLoad（内部/模块/cjs/loader.js:538:12）在Function.Module._load（内部/模块/cjs/loader.js:530:3）在Module.require（internal / modules / cjs / loader.js：637：17）在要求时（内部/模块/cjs/helpers.js:22:18）在对象。（A：\ Portal_project \ customer-portal \ Server \ api \ controllers \ customerController.js：1：78）在Module._compile（内部/模块/cjs/loader.js:689:30）在Object.Module._extensions..js（内部/模块/cjs/loader.js:700:10）在Module.load（internal / modules / cjs / loader.js：599：32）在tryModuleLoad（内部/模块/cjs/loader.js:538:12）在Function.Module._load（internal / modules / cjs / loader.js：530：3）

我希望所有sequelize迁移都能正常工作，并且我的开发服务器也将启动。但我一直收到此类型错误。

这是我的员工模型

'use strict';

module.exports = (sequelize, DataTypes) => {
  const Employee = sequelize.define('Employee', {
    employee_name: DataTypes.STRING,
    employee_id: DataTypes.STRING,
    role: {
      type: DataTypes.ENUM,
      values: ['employee','super employee','admin', 'super admin']
    },
    email_address: DataTypes.STRING,
    id_type: DataTypes.STRING,
    id_number: DataTypes.STRING,
    id_expiry_date: DataTypes.DATEONLY,
    date_of_birth: DataTypes.DATEONLY,
    nationality: DataTypes.STRING,

    },
    date_of_employment: DataTypes.DATE,
    employment_type: {
      type: DataTypes.ENUM,
      values: ['full tme', 'contract']
    },
    date_of_contract_termination: DataTypes.DATE,
    form_of_id: DataTypes.STRING,

    salary_amount: DataTypes.DOUBLE,
    spouse_name: DataTypes.STRING,
    spouse_phone_number: DataTypes.STRING,
    spouse_address: DataTypes.STRING,
    next_of_kin_name: DataTypes.STRING,
    next_of_kin_phone_number: DataTypes.STRING,
    next_of_kin_address: DataTypes.STRING

  }, {
    underscored: true,
  });

  Employee.associate = function(models) {
    // associations can be defined here
    Employee.hasOne(models.IDCardRequest, {
      as: 'employee_id_request'
    })
  };

  Employee.removeAttribute('id');

  return Employee;
};

和迁移文件

'use strict';

另请参阅属于员工的CardRequest模型


'use strict';
module.exports = (sequelize, DataTypes) => {
  const IDCardRequest = sequelize.define('IDCardRequest', {
    card_request_status: DataTypes.ENUM('pending', 'processed'),
    card_renewal_status: DataTypes.ENUM('pending', 'processed')
  }, {
    underscored: true
  });

  IDCardRequest.associate = function(models) {
    // associations can be defined here
    IDCardRequest.BelongsTo(models.Employee,{
      foreignKey: 'employee_id',
      targetKey: 'employee_id',
      onDelete: 'CASCADE'
    })
  };
  IDCardRequest.removeAttribute('id');
  return IDCardRequest;
};

Answer 1

尝试将ENUM声明更新为此：

role: {
        allowNull: false,
        type: Sequelize.ENUM('employee','super employee','admin', 'super admin'),
      }

Answer 2

我通过在模型上指定主键解决了该错误

employee_id: {
  type: DataTypes.INTEGER,
  primaryKey: true,
}

看起来好像是在定义关联但未在模型上指定主键时发生的。

对于OP来说可能为时已晚，但希望这对其他人有帮助。
