如何在sequelize迁移中使用insert()？

Question

我只想在 Sequelize 迁移中创建一行insert()。我已经看过示例，bulkInsert()但不想使用批量。我们用这个函数只创建一行：

insert(instance, tableName, values, options)

但我不明白参数中的实例是什么？我使用它是bulkInsert因为它不询问实例参数。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
    });
  }
};

这里的实例是您使用 sequilize 定义的模型实例。
