I tried passing the session id around to the model, and agree that it is very ugly.
I am curious to know how you can best achieve this scenario without passing in the session variable: abort a delayed_job (or other model based) work item when user changes something - this is mainly required because delayed job workers cost money at my host (heroku) and if the user randomly clicks around on the UI, I dont want to be billed for all the spawned jobs that no one cares about anyway.
