FAQ

What is Prisma Schema Diagram for?

Convert Prisma model blocks into an ER-style schema diagram.

Demo: visualize Prisma models for review

Prisma models contain fields, relations, indexes, and enum choices. A diagram helps teams inspect domain shape before migrations are generated.

  • Check @relation fields and foreign keys together.
  • Review @@unique and @@index near the model they protect.
  • Use the diagram to explain model relationships to frontend and product teams.
model User {
  id Int @id @default(autoincrement())
  email String @unique
  posts Post[]
}
model Post {
  id Int @id
  author User @relation(fields: [authorId], references: [id])
  authorId Int
}

Migration checklist: diagrams do not replace Prisma migrate

The visual preview helps explain schema intent, but migration safety still depends on generated SQL, existing data, and rollout strategy.

  • Review required field additions against existing rows.
  • Check relation deletes and cascade behavior.
  • Compare the diagram with migration SQL before production rollout.
npx prisma migrate diff
npx prisma migrate dev
npx prisma generate

Limites et dépannage

Si l'aperçu échoue, réduisez l'entrée au plus petit exemple complet, validez la syntaxe puis réajoutez les sections.

Considérez l'aperçu comme une surface de revue, pas comme une source de vérité. Les résultats critiques doivent être validés.
