How to use upsert with Prisma? - database

Question

I'm trying to either update or create a record in my Profile table. I'm using Prisma to define the schema and it looks like this:
model Profile {
id String #id #default(cuid())
username String?
about String?
url String?
company String?
userId String
user User #relation(fields: [userId], references: [id])
}
I'm calling the upsert function like this:
const createOrUpdateProfile = await prisma.profile.upsert({
where: { id: id },
update: {
username: username,
about: about,
url: url,
company: company,
},
create: {
username: username,
about: about,
url: url,
company: company,
user: { connect: { id: userId } },
},
});
I'm getting userId from session:
const userId = session.user.id;
I'm getting id, username, about, url, and company from:
//Passed on from await fetch in the form
const { id, username, about, url, company } = req.body;
The issue I'm having is, whenever I'm trying to provide the id, as in where: { id: id }, and it is not already in the database, it doesn't create a new record.
If the id is not in the database, and I do a console.log(id), it gets back as undefined.
If I manually add a record in Profile and connect the user, it updates the record when calling the upsert function.
Can you help me spot what I'm doing wrong?

Answer 1

If I understand your question correctly, the request body may optionally contain an id or be undefined. If the id is present in the request, you want to update the corresponding record. If it isn't, you want to create a new record.
upsert functionality requires a unique identifier that can be used by the database to check whether there is a matching record. The database will then decide what to do. However with an undefined value, prisma cannot work.
You could use a key that will not exist in the database in case the value of id is undefined to make upsert insert the record in this case.
await prisma.profile.upsert({
where: { id: id || '' },
// ...
});
Or you could differentiate the cases and treat them appropriately:
if (id) {
await prisma.profile.update({
where: { id },
data: {
username,
about,
// ...
},
});
} else {
await prisma.profile.create({
data: {
username,
about,
// ...
},
});
}
You might want to think about the case that there is an id given in the body, but it does exist in the database. Do you want the update to fail and reply with an error? Or do you want the database to silently insert? Then use upsert instead of update above.
