Best Practices for Updating Nested Relations in Prisma with NestJS and SQL Server
Hello! I'm working on a project using NestJS, Prisma, and SQL Server, and I need help with updating a complex model with many relations. Here’s the context:
I have the following models with relationships:
Models in Prisma Schema:
Question:
How can I efficiently update these models in a single query or within a transaction? The update should handle creating, deleting, and updating nested related objects. I currently do not have services or controllers for the related models, but I can create them if necessary.
Thank you for any guidance!
