Paranoia is a re-implementation of [acts\_as\_paranoid](http://github.com/technoweenie/acts_as_paranoid) for Rails 3, using much, much, much less code.

You would use either plugin / gem if you wished that when you called `destroy` on an Active Record object that it didn't actually destroy it, but just "hid" the record. 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.

If you wish to actually destroy an object you may call `really_destroy!`. If you wish to actually destroy an object you may call `really_destroy!`.
If a record has `has_many` associations defined AND those associations have `dependent: :destroy` set on them, then they will also be soft-deleted if ``acts_as_paranoid`` is set, otherwise the normal destroy will be called.
