  @Field(),
  @MinLength(2)

您可以使用方法定义自定义装饰器applyDecorators方法。

applyDecorators方法接受PropertyDecorator作为参数。所以请确保将它们转换为PropertyDecorator.

export const NameField = (options?: FieldOptions) =>
  applyDecorators(
    Field() as PropertyDecorator, // convert to PropertyDecorator
    MinLength(2) as PropertyDecorator // convert to PropertyDecorator
  )
)
