# The warning about not setting whodunnit
After upgrading to PaperTrail 5, you see this warning:
> user_for_paper_trail is present, but whodunnit has not been set. PaperTrail no
> longer adds the set_paper_trail_whodunnit before_action for you. Please add this
> before_action to your ApplicationController to continue recording whodunnit.
## You want to track whodunnit
Add the set_paper_trail_whodunnit before_action to your ApplicationController.

See the PaperTrail readme for an example (https://git.io/vrsbt).
## You don't want to track whodunnit
If you no longer want to track whodunnit, you may disable this
warning by overriding user_for_paper_trail to return nil.
```
# in application_controller.rb
def user_for_paper_trail
nil # disable whodunnit tracking
end
```
## You just want the warning to go away
To disable this warning for any other reason, use `skip_after_action`.
```
skip_after_action :warn_about_not_setting_whodunnit
```
