Understanding the use of the _translations query in internationalisation plugin readme

4 replies
Last updated: Jul 6, 2023
I do see this query inside the document internationalisation plugin readme, but I don’t get the _translations query. Why should I use that, if I already get all translations when adding language == $language

// All `lesson` documents of a single language
*[_type == "lesson" && language == $language]{
  title,
  slug,
  language,
  // Get the translations metadata
  // And resolve the `value` reference field in each array item
  "_translations": *[_type == "translation.metadata" && references(^._id)].translations[].value->{
    title,
    slug,
    language
  },
}

The language param is getting you a single translation. The 
_translations
projection is getting all other translations’ title, slug, and language.

That is not how I see it is working. Whenever I use 
*[_type == "lesson" && language == $language]
it will returns me the fully translated document since it created a separate document for each language. This is how the plugin works right now. So this is where my confusion comes from.

Could you clarify this? Sorry for pinging you.

All is working btw, but the docs seems a bit strange to me.

I am struggling with this as well.
Still about to figure out how correctly call the correct translation for a dataset that has a separate language-field (like lesson) rather than a 'staged approach' via the document-internationalization-array plugin (e.g. 'course'). How to practically pass through the $language param into the groq query to only show the lessons in a specific language instead of obtaining runtime errors due to $language.
