I have this User vertex and friends edge. I know two of the users who are friends and one of them wants to unfriend the other. How am I supposed to delete that edge between given vertexes?
So far running both DELETE EDGE FROM :player1 TO :player2 WHERE @class = "friends" and DELETE EDGE FROM :player2 TO :player1 WHERE @class = "friends" (with proper params ofc.) to make sure it's deleted works fine for me but that doesn't feel elegant enough.
You should be able to do it in a single query:
DELETE EDGE friends FROM [:player1, :player2] TO [:player1, :player2]
In case you also have edges from a vertex to itself (eg. from player1 to player1) and you don't want to delete them, you can add a condition:
DELETE EDGE friends FROM [:player1, :player2] TO [:player1, :player2]
WHERE out <> in
