mysql - 通过 sequelize.query() 插入原始查询时不会触发 Hook

Question

我有以下用于 MySQL 数据库的 Employee 模型:

var bcrypt = require('bcrypt');

module.exports = (sequelize, DataTypes) => {
    const Employee = sequelize.define(
        "Employee",
        {
            username: DataTypes.STRING,
            password: DataTypes.STRING,
        }, {}
    );
    return Employee;
};

通过 raw queries 读取包含 10,000 多名员工的 .sql 文件来完成数据库播种。 :

sequelize.query(mySeedingSqlFileHere);

问题是 SQL 文件中的密码是纯文本，我想使用 bcrypt在插入数据库之前对它们进行哈希处理。我以前从未做过批量插入，所以我正在研究 Sequelize docs for adding a hook to the Employee model ，像这样:

hooks: {
  beforeBulkCreate: (employees, options) => {
    for (employee in employees) {
      if (employee.password) {
        employee.password = await bcrypt.hash(employee.password, 10);
      }
     }
  }
}

这不起作用，因为我在重新播种后仍然获得纯文本值 - 我应该寻找另一种方式吗？我正在调查 sequelize capitalize name before saving in database - instance hook

在您使用模型的函数进行数据库操作之前，您的 Hook 不会被调用，因此如果您正在运行原始查询， Hook 将永远不会被触发，

Reason : You can write anything inside your raw query , select/insert/update/delete anything , how does sequelize.js know that it has to fire the hooks. This is only possible when you use methods like

Model.create();
Model.bulkCreate();
Model.update();
Model.destroy;

And as per DOC raw query doesn't have hooks option to add. And for MODEL queries you can check that it has option to enable/disable hook.
