[FEAT] @tsed/prisma should create classes for prisma type definitions

[aksharp12]

Information

• Version: 7.2.3
• Packages:
• @prisma/client: 4.5.0

prisma schema.prisma files allow the definition of type which can provide type safety for su-objects in a model. When using the @tsed/prisma generator, there is an exception that is thrown stating that there was an exception trying to access a property of name which is undefined.

The exception occurs here and here. The issue is that tsed only checks for models and no other objects that are supported by prisma

Example

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["interactiveTransactions"]
}
datasource db {
  provider = "mongodb"
  url      = env("DATABASE_URL")
}
generator tsed {
  provider = "tsed-prisma"
  output   = "../node_modules/prisma"
}
model User {
  /// @TsED.Groups("!creation")
  id        String   @id @default(auto()) @map("_id") @db.ObjectId
  /// @TsED.Email()
  email     String   @unique
  info      Info
  /// @TsED.Groups("!creation")
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
}
type Info {
  firstName String
  lastName  String
}

Acceptance criteria

• running prisma generate, while using the @tsed/prisma generator and having types outside of just model in the schema.prisma, should successfully generate the correct classes and models.

Hello @aksharp12

Thank you for the PR ;)

I think the Type should be an interface and not a class. right ?

See you
Romain

Not a problem at all, @Romakita!

Yes, I would think that an interface would be enough. There is no need for a repository to be generated either since types are referenced in models for prisma

[Romakita]

Finally, the generator will generate a class. It's better to have class for the json-mapper and there is no extra code to support it :)
