Tracking model changes in after_commit :on => :create callback

Is there a way to track changes to model on after_commit when a record is created? I have tried using dirty module and was able to track changes when the record was updated, but when record is created changes are not recorded.

You can't use the rails changed? method, as it will always return false. To track changes after the transaction is committed, use the previous_changes method. It will return a hash with attribute name as key. You can can then check if your attribute_name is in the hash:

after_commit :foo

def foo
 if previous_changes[attribute_name]
   #do your task
 end
end
