How to Expand a Reference on the Object Level

6 replies
Last updated: Jan 11, 2023
Hello all, does anyone know why 
*[_type == 'hos_chapter' && references(@->_id)][0].slug.current
wouldn't work? I've tried 
references(^._id)
too but no joy. Full code...

"relHos": relHos[]{
      "id": @->_id,
      "title": @->title,
      "status": @->meta.status,
      "slug": @->slug.current,
      @->_type == 'hos' => {
        "chapter": *[_type == 'hos_chapter' && references(@->_id)][0].slug.current
      },
    },

chapter
is returning 
null

Also, just to confirm, hardcoding a relevant id does return the chapter, so its something to do with the 
@->
or 
^.
that's causing the issue.

It’ll probably be more performant if you expand the reference on the object level:
relHos[]->{
  _id,
  title,
  "status": meta.status,
  _type == "hos" => {
    "chapter":  *[_type == "hos_chapter" && references(^._id)]
    
  }
}
I’d think in this case that 
^._id
should work for you, however you may have to go up another level (
^.^._id
) because of the conditional.

Thanks

- I did actually implement that technique afterwards, not sure why I had it like that initially. And thanks, all sorted and working now 😊

Maybe changed things around when you were debugging? I’ve done that before! 🙂
