The way I write my DelayedJob classes would be in this format.
I bet that it's not delayed job at all. Maybe the code itself is failing, not the job enqueue/dequeue. Try checking heroku logs and see if it's failing for some reason.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
