Morning everyone. I have a question regarding a nested array of references.My GROQ request is like this (see below).

const exhibitionFields = groq`
  _id,
  name,
  dateStart,
  dateEnd,
  "artworks": artworks[]->{..., "artists":artists[]->{name},"image":image.asset->url},
  "curators": curators[]->{name},
  pressRelease,
  description,
  excerpt,
  "slug": slug.current,
`

Just to be sure: Both 
artworks
and 
artists
are references?
Feb 27, 2023, 2:35 PM
Yes they are!

So what you would like is :
artworks: [
   {
      artists: 'John, Steve',
   }
]
Feb 27, 2023, 2:44 PM
Oh no, as a string.
Feb 27, 2023, 2:45 PM
No, I would like to create a new field:
artists: "John, Sylvie, Bruno"
Feb 27, 2023, 2:45 PM
Or an array like the curators:
"artist": [
    {
      "name": "Sylvie"
    },
    {
      "name": "John"
    },
    {
      "name": "Bruno"
    }
  ]
Feb 27, 2023, 2:46 PM
I'm not following you, because it seems you already have an array of artists?
Feb 27, 2023, 2:48 PM
Yes but the array of artists is inside "artworks".I would like a single field which compile all the artists of the artworks
Feb 27, 2023, 2:48 PM
I can have multiple artworks, each artworks can have multiple artists.
Feb 27, 2023, 2:49 PM
Ah, so a list of all artists for an exhibition?
Feb 27, 2023, 2:49 PM
To simplify, my collection request, I would like a single field where I have all the artists of the artworks.
Feb 27, 2023, 2:49 PM
Exactly. I'm sorry if it wasn't clear.
Feb 27, 2023, 2:49 PM
Not sure if this is the best solution but I have an idea.
Feb 27, 2023, 2:52 PM
Give me a second.
Feb 27, 2023, 2:52 PM
Do you mean it will impact performance of the request?
Feb 27, 2023, 2:52 PM
Not by a lot, but I think the correct way to do this is to query all artists that have an art-piece in that exposition.
Feb 27, 2023, 2:53 PM
artists: [_type=='artist' && _id in artworks[]->artist._ref] { name }
Feb 27, 2023, 2:55 PM
Something along these lines.
Feb 27, 2023, 2:55 PM
Basically, I have a main query that pulls out all the info of the exhibition (including artworks)
Feb 27, 2023, 2:55 PM
Does the above code work?
Feb 27, 2023, 2:59 PM
const exhibitionFields = groq`
  _id,
  name,
  dateStart,
  dateEnd,
  "artworks": artworks[]->{..., "artists":artists[]->{name},"image":image.asset->url},
  "curators": curators[]->{name},
  pressRelease,
  description,
  excerpt,
  "slug": slug.current,
  "artists": [_type=='artist' && _id in artworks[]->artists[]._ref] { name }
`
Feb 27, 2023, 2:59 PM
And the replace "artist" with the correct schema name for your project.
Feb 27, 2023, 3:00 PM
Oh my god, I've been a total dunce.
Feb 27, 2023, 3:14 PM
You can simply do this:
"artists": array::join( array::unique(artworks[]->artists[]->name), ", " ),
Feb 27, 2023, 3:14 PM
This automatically prevents duplicates.
Feb 27, 2023, 3:15 PM
This last bit totally works!
Feb 27, 2023, 4:12 PM
Thanks Alex, appreciate it.
Feb 27, 2023, 4:12 PM
Glad to help!
