Prisma 更新与 WHERE 属性中的关系

Question

Given these schemas:

model awayinfo {
PlayerID   Int        @id
IsAway     Boolean
playerinfo playerinfo @relation(fields: [PlayerID], references: [ID])
}
    
model playerinfo {
name       String    @db.VarChar(15)
ID         Int       @id @unique @default(autoincrement())
awayinfo   awayinfo?
}

How would I create a prisma SQL update for the awayinfo table if the only identifier I have would be the Name of a player and not the ID?

what I tried:

I try to pass something into the WHERE part as seen below:

const result = await prisma.awayinfo.update({
    where: {
      PlayerID: {
        name: name
      }
  },
    data: {
      IsAway: true,
    }
  });

but it always gives me the Error:

Invalid `prisma.awayinfo.update()` invocation: 

Argument PlayerID: Got invalid value
{
  name: 'Dummy'

}
on prisma.updateOneawayinfo. Provided Json, expected Int.

I got pretty desperate and even tried wonky selects like this one

 const result = await prisma.awayinfo.update({
    where: {
      PlayerID: {
      playerinfo: {
        Where: {
        name: name
      },
      select: {ID: true},
    }}
  }, .....

but obviously this would not work aswell. I wonder what I am missing here and I cannot find any example of a condition within the WHERE clause in the prisma documentation

Answer 1

There are two issues here, the first is in your Prisma schema/data model and the second is in your query.

Making name unique

Firstly, if you want to uniquely identify a record in the playerinfo table with just the name property, this property must be unique . Otherwise, it's not possible for your database (and Prisma) to know which player info record to update in case there are multiple records with the same name property.

Update your schema accordingly:

model playerinfo {
  name     String    @unique @db.VarChar(15)
  ID       Int       @id @unique @default(autoincrement())
  awayinfo awayinfo?
}

Rewriting the update query

Since the where condition in your update references a property playerinfo model, that is where you should begin your query. Here's what it looks like:

const data = await prisma.playerinfo.update({
    where: {
        name: name
    }, 
    data: {
        awayinfo: {
            update: {
                IsAway: true
            }
        }
    }
})
