Activejob fails deserializing an object
rails-activejob, ruby-on-rails, sidekiq
Solution
Sidekiq is so fast that it executes your job before the database has committed the transaction. Use `after_commit` to create the job.
Problem
To test that my mails are being sent I'm running `heroku run rails c -a my_app`. Then I enqueue the job and it is enqueued fine. However, when I go to Redis and see queued jobs the job is not there. Instead, it is on "retry". This is what I see: `{"retry":true,"queue":"default","class":"ActiveJob::QueueAdapters::SidekiqAdapter::JobWrapper","args":[{"job_class":"SendMailJob","job_id":"4b4ba46f-94d7-45cd-b923-ec1678c73076","queue_name":"default","arguments":["any_help",{"_aj_globalid":"gid://gemfeedapi/User/546641393834330002000000"}]}],"jid":"f89235d7ab19f605ed0461a1","enqueued_at":1424175756.9351726,"error_message":"Error while trying to deserialize arguments: \nProblem:\n Document(s) not found for class User with id(s) 546641393834330002000000.\nSummary:\n When calling User.find with an id or array of ids, each parameter must match a document in the database or this error will be raised.

I've tried to add `after_create` callback (Mongoid) but doesn't make any difference. Any idea on what is happening? Thanks.
