javascript - 如何在 sequelize 迁移中使用 insert()？

Question

我想在 Sequelize 迁移中使用 insert() 只创建一行。我看过 bulkInsert() 的示例，但不想使用批量。我们有这个函数来只创建一行:

insert(instance, tableName, values, options)

但是我不明白param里的instance是什么？我正在使用 bulkInsert 因为它不要求实例参数。如果您可以在我下面编写的代码中添加插入，那就太好了。迁移库:https://github.com/sequelize/sequelize/blob/master/lib/query-interface.js

//Code for insertion using bulkInsert
module.exports = {
  up: queryInterface => {
    queryInterface.describeTable("Platforms").then(attributes => {
      return queryInterface.bulkInsert("Platforms", [
        {
          id: 6,
          display_name: "Booking.com",
          code: "booking.com"
        }
      ]);
    });
  },
  down: queryInterface => {
    return queryInterface.bulkDelete("Platforms", {
      id: 6
    });
  }
};

  import Platform from '../models/Platform';
  module.exports = {
  up: queryInterface => {
    queryInterface.describeTable("Platforms").then(attributes => {
      return queryInterface.insert(Platform, "Platforms", [
        {
          id: 6,
          display_name: "Booking.com",
          code: "booking.com"
        }
      ]);
    });
  },
  down: queryInterface => {
    return queryInterface.bulkDelete("Platforms", {
      id: 6
    });
  }
};

此处的实例是您使用 sequilize 定义的模型实例。
