Conditional values in GROQ queries
Only return a value when a condition is fulfilled
The query
*[
_type == "article"
&& (
!defined(image.altText)
|| (
count(body[_type == 'image' && !defined(altText)]) > 0
)
)
] | order(publishedAt desc) {
_id,
title,
// Condition 1 - document level
!defined(image.altText) => {
'image': image.asset,
},
// Condition 2 - inside portable text
count(body[_type == 'image' && !defined(altText)]) > 0 => {
"bodyImage": body[_type == 'image']
},
}Let's assume you want to check which images in your documents have an altText set. These image fields are either on the first document level or in the body field (portable text) as a custom block of type image. To get all documents with images without an altText you can use conditional value fetching in your query.
You can setup conditions using this logic in GROQ:
CONDITION => { VALUES_YOU_WANT},

What to do when Studio crashes due to conflicts in dependency versions?
If you install plugins or other packages with conflicting (peer) dependencies, you can use this useful workaround to unblock yourself.

Use the validation status of a document in your custom document actions
When creating custom document actions, it can be necessary to check, wether all validation rules are full-filled.

Create a new reference document with parameterised initial Values
If you want to make it possible to use parameterised initialValue templates in reference fields, this is how!

Create a copy of an object and change a key-value pair
Sometimes you need to change only one key-value-pair in your data, this is how you can do it in 2 lines
