Payment

We'll now create the Payment model, which will be very simple.

model Payment {
  id Int @id @default(autoincrement())

  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
}

Let's then create a relation between Order and Payment. An order may or may not have a payment, and a payment always belongs to an order. Therefore, we have a one-to-one relation. Lastly, we want that an order is deleted together with its payment.

So, in the Order model we should have

payment Payment?

And in Payment

order   Order @relation(fields: [orderId], references: [id], onDelete: Cascade)
orderId Int   @unique

Then, let's generate and run its migration

yarn migrate:create create-payment
yarn migrate:run

And now, create the payments resource. Remember to choose no to CRUD entry points.

nest g res domain/payments
