Custom imports

[apss-pohl]

Hi,

it would be nice to be able to configure custom imports.
When you want to use a function for the "class-validator" right now you can`t import it automated. In this example i need to import the "createValidationError" function.

model customer {
  /// @Validator.MaxLength(3, {message: createValidationError('form_string_max', ['max'])})
  number               BigInt    @db.UnsignedBigInt
}

Will be missing

import { createValidationError } from '@m/common/utils/validation-helper';

In the generated input files.

A workaround is to create a dummy field decorator:

model customer {
  /// @CustomValidation.dummy()
  /// @Validator.MinLength(3, { message: CustomValidation.createError('form_string_min', ['min'])})
  number               BigInt    @db.UnsignedBigInt
}

Added to generator section:

    fields_CustomValidation_from = "@m/common/utils/validation-helper"
    fields_CustomValidation_input = true
    fields_CustomValidation_output = false

Will result in the wanted import:

import * as CustomValidation from '@m/common/utils/validation-helper';

But clearly rather ugly solution

It would be great if having some solutions for this, like triple slash to add custom imports...

Hello, sorry to tag you here.
Could we please have your input on this issue? I plan to combine the nestjs-i18n library for validation messages. Importing it after code generation defeat the whole purpose.

Thanks again for your hard work
