Best Practices for Error Handling When Updating Bridge Table (Composite IDs)
Wrapping the update in a transaction can ensure that all operations within the transaction scope either complete successfully or roll back together, which is crucial for maintaining database consistency, especially if the update operation depends on multiple steps or includes additional related changes. Using a transaction ensures atomicity. If any part of the update process fails, the transaction will roll back, leaving the database in a consistent state. This is especially useful if there are multiple dependent operations or if future modifications might require additional steps within the update process.

When you generate the Prisma client, you also generate types. Simply import those types:
import type { YourType } from '@prisma/client';
import type { YourType } from '@prisma/client';
I forgot how types are generated from the client 😅

Best Practices for Error Handling When Updating Bridge Table (Composite IDs)
Hi :vmathi: Tt is necessary to verify that the two records comprising its composite ID exist before updating the bridge table. This is to ensure data integrity and to avoid potential errors during the update process. You can do it using something like that:
export async function updateFacilityWorker(
facilityUuid: FacilityWorker["facilityUuid"],
workerUuid: Worker["uuid"],
data: Omit<Prisma.FacilityWorkerUpdateInput, TimestampFields>
): Promise<UpdatedFacilityWorker> {
// Check if the facility and worker exist
const facilityExists = await prisma.facility.findUnique({
where: { uuid: facilityUuid },
});

const workerExists = await prisma.worker.findUnique({
where: { uuid: workerUuid },
});

if (!facilityExists) {
throw new Error(`Facility with UUID ${facilityUuid} does not exist.`);
}

if (!workerExists) {
throw new Error(`Worker with UUID ${workerUuid} does not exist.`);
}

// Proceed with the update inside a transaction
return prisma.$transaction(async (prisma) => {
return prisma.facilityWorker.update({
select: {
facilityUuid: true,
workerUuid: true,
rating: true,
status: true,
},
where: {
facility_worker_id: { facilityUuid, workerUuid },
},
data,
});
});
}
export async function updateFacilityWorker(
facilityUuid: FacilityWorker["facilityUuid"],
workerUuid: Worker["uuid"],
data: Omit<Prisma.FacilityWorkerUpdateInput, TimestampFields>
): Promise<UpdatedFacilityWorker> {
// Check if the facility and worker exist
const facilityExists = await prisma.facility.findUnique({
where: { uuid: facilityUuid },
});

const workerExists = await prisma.worker.findUnique({
where: { uuid: workerUuid },
});

if (!facilityExists) {
throw new Error(`Facility with UUID ${facilityUuid} does not exist.`);
}

if (!workerExists) {
throw new Error(`Worker with UUID ${workerUuid} does not exist.`);
}

// Proceed with the update inside a transaction
return prisma.$transaction(async (prisma) => {
return prisma.facilityWorker.update({
select: {
facilityUuid: true,
workerUuid: true,
rating: true,
status: true,
},
where: {
facility_worker_id: { facilityUuid, workerUuid },
},
data,
});
});
}

how to import prisma client on a client without compromising credentials
Hi :vmathi: You an import Prisma types safely, those are only Typescript types. You just won't import the prisma client at any cost in your client or it will be compromised

How can I use plain object instead of composite types ?
Hi :vmathi: Sorry to hear that! You can try to upgrade to a fixed version, v4.16.2-dev.2, which should fix some issues with composites:
Another option is to try to have explicit type selection by explicitly select the fields you need in your queries:
const user = await prisma.user.find({
select: {
profile: {
select: {
name: true,
},
},
},
});
console.log(user.profile.name);
const user = await prisma.user.find({
select: {
profile: {
select: {
name: true,
},
},
},
});
console.log(user.profile.name);
You can also use Prisma's $extends feature to create custom extensions that simplify access to your nested fields, allowing you to define getter methods to access fields directly without navigating through scalars:
const prisma = new PrismaClient().$extends({
result: {
user: {
profile: {
needs: { profile: true },
compute(user) {
return user.profile.scalars;
},
},
},
},
});
const prisma = new PrismaClient().$extends({
result: {
user: {
profile: {
needs: { profile: true },
compute(user) {
return user.profile.scalars;
},
},
},
},
});
The latest option i would suggest would be to downgrade to v4.15.0 if none of the options above work

How to run safe migrations
Hi :vmathi: First create a new migration:
npx prisma migrate dev --create-only
npx prisma migrate dev --create-only
Then add your migration to the new created file. If you want to set a default value for the new field for existing records, you can add an UPDATE SQL command before the ALTER TABLE command that adds the new field. For example, if you're adding a businessId field to the hairstyle table and want to set a default value of NULL for existing records, you could add:
UPDATE hairstyle SET businessId = NULL;
UPDATE hairstyle SET businessId = NULL;
If you want to remove records that do not have corresponding references, you can add a DELETE SQL command. For example:
DELETE FROM hairstyle WHERE businessId IS NULL;
DELETE FROM hairstyle WHERE businessId IS NULL;
Whenever you're ready, run your new migration:
npx prisma migrate dev
npx prisma migrate dev

Well, if you're using Mongo, it should be an object. If you delete the parent object, it should delete everything
