• supervisors
• admins
• volunteers

Description

This controller action has issues with N+1 queries (method call makes an additional method call for each item it finds.)

You can see these in our scout: https://scoutapm.com/shares/e7dee11b-72d2-4e94-b6b2-853908ded0a8

Go through all the methods to ensure all the needed data is preloaded in the first query and no additional calls to the database need to be made.
