import { ArrayMaxSize, ArrayMinSize, IsArray, IsBoolean, IsString, ValidateNested } from "class-validator";
import { Transform, Type } from "class-transformer";

class CreateAnswerDto {
  @IsBoolean()
  readonly isTrue: string;

  @IsString()
  title: string;

  @IsString()
  description: string;
}

const transformAnswers = answers => {
  return JSON.parse(answers.value);
};

export class CreateQuestionDto {
  @Transform(transformAnswers, { toClassOnly: true })
  @IsArray()
  @ArrayMinSize(4)
  @ArrayMaxSize(4)
  @ValidateNested({ each: true })
  @Type(() => CreateAnswerDto)
  readonly answers: CreateAnswerDto[];

  @IsString()
  readonly title: string;
}

所以我有相同的代码，并且我想验证答案中的每个对象字段，但此代码不起作用。如果我发送了错误的数据，则此验证会跳过它。我怎样才能正确验证我的答案？

谢谢你的帮助！
