relations to the same table

Is this not possible to do?

export const CompaniesRelations = relations(Companies, ({ many, one }) => ({
  clients: many(Companies),
  parentCompany: one(Companies, {
    fields: [Companies.parentCompanyId],
    references: [Companies.id],
  }),
  websites: many(Websites),
}));

export const CompaniesRelations = relations(Companies, ({ many, one }) => ({
  clients: many(Companies),
  parentCompany: one(Companies, {
    fields: [Companies.parentCompanyId],
    references: [Companies.id],
  }),
  websites: many(Websites),
}));

I get an error when rinning the studio: Error: There are multiple relations between "__public__.Companies" and "companies". Please specify relation name this error disappears if i remove the self referential relations

Hey! Is this relationship described in your schema?

hey. no, it's not, but that has never been a problem

Where did you get this relation from then?

it just "is"

You need to specify relationName when you define multiple relations between the same two tables https://orm.drizzle.team/docs/rqb#disambiguating-relations
