How do you do exception management with delayed job?

My application needs to parse a user-generated CSV file. And, once uploaded, the application wil开发者_开发问答l queue it in delayed job to be processed. My question is, how do you usually handle the exceptions that might happen during the content parsing stage? Do you store all the error messages in exception-objects before display it to user?

Thank you.

As the job is delayed, I would like to give all the errors in the CSV file at once. So that users do not end up iterating multiple times (fixing 1 error at a time).

One thing you can do is store all errors in a DB (in an suitable object). This would also enable to you analyze what kind of errors users are generally having and help them in reducing those.
