What happened?

I am trying to reproduce the example of the documentation : https://docs.adminjs.co/basics/features/relations

I have this prisma model :

generator client {
    provider = "prisma-client-js"
}

datasource db {
    provider = "postgresql"
    url      = env("DATABASE_URL")
}

model Organization {
    id      Int      @id @default(autoincrement())
    name    String
    persons Person[]
}

model Person {
    id             Int          @id @default(autoincrement())
    name           String
    email          String
    organization   Organization @relation(fields: [organizationId], references: [id])
    organizationId Int
}

and these two definitions for AdminJS :

export const createPersonResource = () => ({
  resource: {
    model: getModelByName('Person'),
    client: prisma,
  },
  features: [targetRelationSettingsFeature()],
});

export const createOrganizationResource = () => ({
  resource: {
    model: getModelByName('Organization'),
    client: prisma,
  },
  features: [
    owningRelationSettingsFeature({
      componentLoader,
      licenseKey: process.env.ADMINJS_LICENSE_KEY,
      relations: {
        persons: {
          type: RelationType.OneToMany,
          target: {
            joinKey: 'organizationId',
            resourceId: 'Person',
          },
        },
      },
    }),
  ],
});

When i open a detail page of an Organization, i have this error in the terminal (log output below)

Relevant code that's giving you issues

In the convertFilter function, if i log the filters i got this :

{
  organizationId: { path: 'organizationId', property: null, value: '2' }
}

Additional informations : same bug with TypeOrm, but fixed adding @column around organizationId inside Person class entity.

Just checked this in a test project and it'd worked for me when I used organization instead of organizationId for joinKey. Looks like @adminjs/prisma uses relation fields instead of FKs to query relationships.

Thanks a lot! It's definitely works!
