Mixin

🔋 ZModel vs Prisma Schema

Mixin is a ZModel concept and don't exist in PSL.

info

Mixin was previously known as "abstract inheritance" in ZenStack v2. It's renamed and changed to use the with keyword to distinguish from polymorphic model inheritance.

Very often you'll find many of your models share quite a few common fields. It's tedious and error-prone to repeat them. As a rescue, you can put those fields into custom types, and "mix-in" them into your models.

Before:

model User {
    id        String @id
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
    email     String @unique
}

After:

type BaseFieldsMixin {
    id        String   @id
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
}

model User with BaseFieldsMixin {
    email String @unique
}

A model can use multiple mixins as long as their field names don't conflict.

Mixins don't exist at the database level. The fields defined in the mixin types are conceptually inlined into the models that use them.
