Need to work with notification class Task < ActiveRecord::Base

attach_notification(:assign_to_me, [:assign_id]) do |task, current_user|
    if task.user == current_user
        notify task.user
    end
end

end

Changes render support

1. For create the changes are shown in one sentance

2. For update each changes are shown in seperate sentence

   Translation keys:
       -> nil to value
       -> value to another value
       -> value to nil

3. For fields ends with _id, the model has to respond with a readable name

4. Any changes can be notifuied to users.

5. Notification and the history will render the same partial or use the same translation key.

Sample translation file

en:

auditlog:
  Default:
    created: %{model} created
  Task:
    created: Task created
    assigned_to_id:
      cleared: Unassigned from %{assigned_to_was}
      changed: Assigned from %{assigned_to_was} to %{assigned_to_now}
      set: Assigned to %{assigned_to_now}
