How to resolve deserialization error in delayed job?

Question

I am trying to use DelayedJob and the job is failing, giving the following error in the database:

{Delayed::DeserializationError
/Library/Ruby/Gems/1.8/gems/delayed_j         


        

Answer 1

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.
