Any idea how i can query and open up the reference to carousels?


 title: 'Sidemoduler',
      name: 'modules',
      type: 'array',
      description: 'test',
      of: [
        { type: 'icons'},
        { type: 'reference',
          title: 'Carousel',
          name: 'carousel',
            to: [{ type: 'carousels' }]
          }
      ],

all i get with this query :

 *[_type == 'page']{
 modules[]{
   _type=="carousel" =&gt; {...}
    }
    }

is :

_key:3931b8414f42
_ref:ad5572b5-104d-4ffd-a6f4-a5058f2392f4
_type:carousel

user F

. Could you please try changing that

_type

line in your query to this?

_type=="reference" =&gt; @-&gt;

thanks alot! So what does the @-> actually do? open all refs?

You can think of

a bit like

this

, so it’s saying “for anything that’s a reference type, dereference it.”

Throughout the docs you’ll tend to see the dereference operator (

-&gt;

) following some property, such as here , but in this case we can’t really do that because what “this” is, changes.

is the thing that’s currently in scope, and when it’s of the “reference” type, it gets applied. You might write the same thing as:

select(
  _type == 'reference' =&gt; @-&gt;,
  @
)
