I have used delayed_job in a ruby on rails application. As part of that application I have a model Student which is being observed by delayed_job so that a certain action can be taken on update of a Student. But I don't want to call delayed_job on update of certain columns of Student. So basically I want to skip some specific columns of a model in delayed_job.

I have thought of doing that by using some application level flag variables so that delayed_job will only be called when only the flag is reset. But I'll have a problem when multiple instances of the same application process. I mean concurrency issues may arise. So it will not work. I have no idea if there is any way to do that.

why don't you use it manually for some actions? – Rajdeep Singh May 23 '14 at 04:55
Sorry, I don't get your point. Are u suggesting not to use delayed_job? – Joy May 23 '14 at 04:56
No, I'm saying instead of using it on whole model use it manually in controller actions – Rajdeep Singh May 23 '14 at 05:02
