Nested types

[unkindypie]

Feature request: add support for nested DTOs/arrays of nested DTOs.

For example, we have this DTO:

 class RegisterUserDto {
  @ApiProperty()
  @IsEmail()
  email: string;

  @ApiProperty()
  @IsString()
  firstName: string;

  @ApiProperty()
  @IsString()
  lastName: string;

  @ApiProperty({ nullable: true })
  @IsString({ each: true })
  expertiseKeywords?: string[];

  @ApiProperty({ type: [CreateCredentialDocument], nullable: true })
  @ValidateNested({ each: true })
  @Type(() => CreateCredentialDocument)
  credentialDocuments?: CreateCredentialDocument[];
}

Then we will try to call route that takes this DTO with the following from data:

Server will get this object:

{ email: 'qwdwd@qwdq.com', firstName: 'eqwdfewf', lastName: 'qwdwedf', birthDate: '2021-06-28T14:41:28.251Z', bio: 'ewfewf', location: 'wefewfewf', jobTitle: 'wefweewf', linkedInProfileUrl: 'qdqwdqwdqwd', expertiseKeywords: [ 'lalala' ], 'credentialDocuments[0].documentTypeId': '1' }

As you can see, array of primitives works correctly while array of objects just creates string keys.

Hi, the problem is that the request you are sending via postman is not correct.
Use credentialDocuments[0][documentTypeId] instead of credentialDocuments[0].documentTypeId

It works, thank you. I should have tried it.
