Display all the tags (and their category) of a single recipe.

Last updated: Feb 10, 2021
My project is a recipe-app in React and I want to display all the tags (and their category) of a single recipe.I just can’t figure out how to write the schema’s.
When I inspect the document of the recipe, I only get _key and _ref.
What did I do wrong?

Hi Pieter, this is correct - the 
_key
is to give each array item a unique identifier and the 
_ref
is the ID of the referenced document. To show these references in your React app, you will need to use the dereferencing operator 
->
to join them in your query.
For example, if you're using GROQ:

*[_type == "recipe"]{
  ...,
  thetags[]->{
    ...,
    category->
  }
}
