node.js - Sequelize 错误 : cannot find property "startYear" of undefined

Question

我正在使用 sequelize cli 并为每个生成的模型生成每个迁移文件，我正在尝试使用单个迁移文件生成所有表，因为它们相互依赖，但我不断收到此错误

找不到未定义的属性 startYear

另外，我需要一个关于如何使用 sequelize cli 在 sequelize 中更改模型的教程。

在 validate 参数中使用 options 函数:

{
  validate: {
    endYearIsAtLeastStartYear() {
      if (this.endYear < this.startYear) {
        throw new Error('End year must be equal to or higher than start year')
      }
    }
}
