Bug description

We currently have a monorepo with Angular/NestJS that is using Prisma models both in the frontend and backend to coordinate the sharing of DTO information without blowing up the backend/frontend with a bunch of DTO classes.

However, when moving over to testing the new Prisma client generator, we found that non of our relationships are exported off the *Model interface. Instead, we've needed to create additional models interfaces that represent these relationships.

We'd really prefer it if the *Model just included the relationships between the different models in the database (and the Prisma scheme).

Severity

🔹 Minor: Unexpected behavior, but does not block development

Reproduction

Expected vs. Actual Behavior

Expect the Model relationships to be auto-generated by Prisma.

Frequency

Consistently reproducible

Does this occur in development or production?

Only in development (e.g., CLI tools, migrations, Prisma Studio)

Is this a regression?

Yes, this behavior was not present in the prisma-js generator.

Workaround

Using the old generator or creating custom models works.
