Prisma Schema Decorators

Prisma schema decorators allow you to create dto and entities. You can use them with /// comments or by configuring them directly in the Prisma schema file. This guide focuses on class-validator decorators and additional Prisma decorators that can be used for generating DTOs and entities.

Class-validator Decorators

Class-validator decorators are also available for use in Prisma schemas. For a comprehensive list of class-validator decorators, refer to the official class-validator documentation.

Additional Prisma Decorators

• @Ignore: Ignores the decorated property in all generated DTOs and can be used on both models and fields.

• @NoAdd: Ignores the decorated property in the generated create DTO.

• @NoSet: Ignores the decorated property in the generated update DTO.

• @OptAdd: Makes the decorated property optional in the generated create DTO.

• @OptSet: Makes the decorated property optional in the generated update DTO.

• @NoEntity: Excludes the decorated field from the generated entity.

• @RReq: Makes the decorated relation required in the all generated DTO.

• @RAddOnAdd: Makes the additional class for create when create

• @RLnOnAdd: Makes the additional class for connect when create

• @RAddOnSet: Makes the additional class for create when update

• @RLnOnSet: Makes the additional class for connect when update

• Add @RAddOn and @RLnOn for connect or create

All additional Prisma decorators can be used on fields, and the @Ignore decorator can be used on both models and fields.

Configuring Decorators

Decorators can be configured using the configuration file or Prisma schema config or by adding them directly in the schema.

Using /// Comments

model User {
  id    Int    @id @default(autoincrement())
  /// @NoSet @IsEmail()
  email String
}

/// @Ignore
model Ignored {
  id Int @id @default(autoincrement())
}
