Returning relationships without the related object about jsonapi HOT 2 OPEN

I'm trying to figure the same thing out at the moment, this is fairly old so unsure if this is still a problem for you but you could provide the links by implementing JSONAPIRelationshipLinks as shown in the examples:

func (blog Blog) JSONAPIRelationshipLinks(relation string) *jsonapi.Links {
	if relation == "posts" {
		return &jsonapi.Links{
			"related": fmt.Sprintf("https://example.com/blogs/%d/posts", blog.ID),
		}
	}
	if relation == "current_post" {
		return &jsonapi.Links{
			"related": fmt.Sprintf("https://example.com/blogs/%d/current_post", blog.ID),
		}
	}
	return nil
}

this won't give you the data field though (id/type) as you like, but should still comply with the spec as I understand it as it states it must include at-least one: http://jsonapi.org/format/#document-resource-object-relationships so the links should be enough to satisfy it and give the consumer a location to find it or the hint that it might be able to be specified with the include param.

Ideally I'd also like to include the id and type as well, but don't see a way of doing that currently.

I suppose the solution, if you have e.g. a one-to-many relationship is to create a struct named after the relationship, which implements the JSONAPILinks method which returns the self and related links, it should then only contain the primary,<name_of_relationship> and should be filled out by separate db calls which fetch only the relationship IDs.

This library sells it self on the fact that you shouldn't create glue structs though, so there should be an proposal to get this behavior built into the tags etc. Nevertheless, you still have to built some code that only fetches the IDs of a specific relationship.

EDIT: never mind, that doesn't work either. It puts the links object inside of the data.
