Nested admin saves vs relational schema
Le problème
Project case studies include slides, challenges, screenshots, and translations—naive form posts dropped nested arrays on partial saves.
Comment je l'ai résolu
Server Actions merge nested payloads server-side with explicit delete-and-recreate for child collections inside Prisma transactions.
await prisma.$transaction(async (tx) => {
await tx.projectSlide.deleteMany({ where: { projectId } })
await tx.project.update({
where: { id: projectId },
data: { slides: { create: slides } },
})
})
revalidateTag('projects')
