Paranoia is a re-implementation of acts_as_paranoid for Rails 5, 6, and 7, using much, much, much less code.

Paranoia does this by setting a deleted_at field to the current time when you destroy a record, and hides it by scoping all queries on your model to only include records which do not have a deleted_at field.
