one-to-many

I might be asking something simple or have to change my model but I thought I'd ask cause I've been stuck for a while. I have an images table

export const images = pgTable('images', {
  id: text('id')
    .$defaultFn(() => `image_${nanoid()}`)
    .primaryKey(),
  label: text('label'),
  url: text('url'),
  resourceId: text('resource_id'),
  resourceType: text('resource_type'),
  createdAt: timestamp('created_at').defaultNow().notNull(),
});

export const images = pgTable('images', {
  id: text('id')
    .$defaultFn(() => `image_${nanoid()}`)
    .primaryKey(),
  label: text('label'),
  url: text('url'),
  resourceId: text('resource_id'),
  resourceType: text('resource_type'),
  createdAt: timestamp('created_at').defaultNow().notNull(),
});

you can see I have a resourceId and a resourceType because I have different things that can have relations to images. I know I could create a table inbetween but I thought I'd try there, where I'm stuck is on setting up the relation. All the documentation shows

many(images)

many(images)

But when I run it I get an error on the resource I'm doing the with as "There is not enough information to infer the relation" Any suggestions?

You have to set up the relation on both sides In the table that has the images you set up a many(images) In the images table, you set up the one(whatever_table_name_uses_images)

And try to add a relation name (the same) on both sides as well. Like many(images, { relationName: "resources.image" }) or something like that
