Delayed::DeserializationError in rails 3

[romaluca]

Hi i'm using delayed job gem for my site. In rails 2.3.8 i had no problems, but when i pass to rails 3 the process starts but in the delayed_jobs table of db i receive this error:

{Delayed::DeserializationError

Thanks!

Same here. The majority of my jobs run fine. I have one in particular which throws the Deserialization error. The job that works is going against an AR model which has been saved. The job that fails is working on an unsaved AR model object. The AR model is the same in both jobs.

I believe this occurs when you run a job against an unsaved or deleted AR object since the deserialization for AR loads the record by id. An exception should probably be thrown if you attempt to delay a method on an unsaved AR object.
