Hi,
You could try to do it like this...
Use a hashmap instead of a vector in the atom:
(def room-list (atom {}))
Insert rooms using a hashmap for the user-id's:
(swap! room-list assoc "67890" {:user-list {"id-3" {:name "name-3"}}})
You can now find a user in a room like this:
(get-in @room-list ["67890" :user-list "id-3"])
To remove a user from a room you can use:
(swap! room-list update-in ["67890" :user-list] dissoc "id-3")
Good luck!
