I’ve struggled with this for too long now. I haven’t been able to piece together the documentation for querying a many-to-many relationship for the records of one collection that have no relations through the “joins” collection.
I have songs, tags, and song_tags. I want to get all the songs that haven’t been tagged.
I think what I want to do is query for all the songs with an index, and then do a
Difference of that and all the song ids present in the
all_song_tags index. I’m still struggling to find the right FQL syntax for that mapping.
I’m also using the
@relation resolver in GraphQL, if that makes a difference.
