custom import

[greatbooms]

Hi, I have a question. I want to print a constant or dynamic message in the message option in class-validator, but I can't do my import statement at the top. Is there any way to solve this?

generator graphqlmodel {
  provider = "prisma-nestjs-graphql"
  output   = "../model/src/lib/@generated"
  reExport = All
  fields_ErrorMessage_from = "@temp/constants" 
  fields_ErrorMessage_defaultImport = "{ ErrorMessage }"
  fields_ErrorMessage_input = true
  fields_ErrorMessage_output = true
  fields_Validator_from = "class-validator"
  fields_Validator_namedImport = true
  fields_Validator_input = true
  fields_Validator_output = true
}

model User {
  /// @Validator.IsNotEmpty()
  /// @Validator.IsString()
  /// @Validator.MaxLength(191)
  id                 String         @id @default(cuid())
  /// @Validator.IsEmail({}, { message: ErrorMessage.MSG_EMAIL_RULES_VIOLATION, }, )
  /// @Validator.IsNotEmpty({ message: ErrorMessage.MSG_NOT_FOUND_EMAIL, } )
  /// @Validator.MaxLength(256)
  email              String?        @unique @db.VarChar(256)
}

import { ErrorMessage } from '@temp/constants';

dto file doesn't have that import

No, it is not possible to have variables/dynamic values in directive comments.

Have you tried people solutions for class-validator?
