From 6366f2e61f14ee83856e7cdabaab21550b3eb910 Mon Sep 17 00:00:00 2001 From: Martin Janse van Rensburg Date: Mon, 6 Jul 2026 18:17:07 +0200 Subject: [PATCH] blog: refresh Prisma Schema Language post, answer-first + verified on 7.8 Shortlist #5 (32k impressions, 0.34% CTR): the core fix is the meta and intro. metaDescription was "An article discussing..." with zero answer content; now an answer-first definition. Intro rewritten as a standalone definition block for extraction. Corrections verified on Prisma ORM 7.8.0 against a live database: - The Customer/Order sample was invalid PSL: it failed prisma validate with "missing an opposite relation field" (relations require both sides). Added the orders back-relation; validated. - All other schema samples and the findMany query verified via validate, db push, generate, and live queries including the implicit many-to-many. Also: dead /docs/orm/tools/prisma-cli link repointed to the CLI reference, dead quickstart-prismaPostgres CTA repointed to the current Prisma Postgres quickstart, added multi-file schema note (GA since 6.7.0, prisma.config.ts directory in v7) linking the refreshed multi-file post, and added the Prisma Next section per refresh policy, framed as the data contract carrying PSL's ideas forward. Slug, author, publish date unchanged; updatedAt bumped.
