Validation Rule that checks on attributes of related object

Question

I am struggling with the syntax for validation rules. I get the picture and I understand what all examples are doing, but I do not see how I can properly validate the an attribute for a linked asset.

E.g. we have business terms that translate to other languages. The language is indicated with a code in an attribute. Does somebody have an example/code snippet on how I could check that the assets that are linked do not have the same language code?

This is a great topic for a coaching session.

Here’s my 5min attempt at what it could look like.

rule {
  given {
    assetLanguages = relations['language']?.collect{it.name}
    otherLanguages = relations['translation']?.collect{ it.relations['language']?.collect{it.name}}.flatten().toSet()
  }
  then {
    isAny(assetLanguages, { otherLanguages?.contains(it)})
  }
}
