Getting seemingly incorrect relation error

  parentProductSetTemplate: one(productSetTemplates, {
    fields: [productSets.parentProductSetTemplateId],
    references: [productSetTemplates.id],

    fields: [productSets.productSetTemplateId],
    references: [productSetTemplates.id]

Error: There are multiple relations between "productSets" and "ProductSetTemplate". Please specify relation name

Shouldnt this be sufficient for relation names? If not, i dont see how i could even add one? my schema was working with prisma so i dont think i need to add another FK

I guess it should be enough to only add one relationName the way you have it I think that drizzle just shorcuts to an error as soon as it sees several relatiions with a lower number of relation names You can just add the relation name to the other relation just to satisfy drizzle

how would i do that without an additional foreign key productSet: one(productSets) in order to add a relation name i also need fields and references

productSet: one(productSets, {
  references: [productSets.productSetTemplateId],
  fields: [productSetTemplates.id],
  relationName: "myRelationName"
}),

productSet: one(productSets, {
  references: [productSets.productSetTemplateId],
  fields: [productSetTemplates.id],
  relationName: "myRelationName"
}),

Just the opposite to the other side of the relation? I not completely sure, but it seems to me that that should work
