Test project for groq quries

Getting Started

There are two categoryFilters in the postCollection schema: categoryFilter and categoryFilterOld. The old one works, the new does not.

For the old one, a categoryFilter in postCollection could only have a reference to a single category. For the new one, the categoryFilter is an array of references to category.

To test, replace the groq for fetching 'posts' in groq/getPageQuery.

# this is the new filter that does not work.
'posts': *[_type == "post" && category._ref in ^.categoryFilter[]._ref]

# this is the old filter that works.
'posts': *[_type == "post" && category._ref == ^.categoryFilterOld._ref]
