ZenStack — Schema Modeling (ZModel)

ZModel is ZenStack's schema language — a superset of Prisma's schema. The schema lives at zenstack/schema.zmodel by default. For access policies/validation use zenstack-access-control; for queries use zenstack-querying.

After editing the schema:

zen check      # only validate the schema for syntax/semantic errors (use --schema <file> for a non-default path)
zen generate   # regenerate the database client — also validates the schema as it compiles

Run zen check when you just want to confirm the schema is valid; run zen generate when you want to regenerate the client (the normal step after a schema change).

Strings accept both single and double quotes. Every valid Prisma schema is valid ZModel, so existing Prisma knowledge transfers directly — the sections below cover both the basics and the additions ZModel layers on top.
