Question

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

insert(instance, tableName, values, options)

但我不明白param中的实例是什么？我正在使用bulkInsert，因为它没有要求实例param。如果您可以在我下面编写的代码中添加插入，那将是很棒的。迁移lib：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。
