Explicit soft deletion for ActiveRecord via deleted_at and default scope + callbacks.
Not overwriting destroy or delete.
Install
gem install soft_deletion
Or
rails plugin install git://github.com/grosser/soft_deletion.git
Usage
# mix into any model ...
class User < ActiveRecord::Base
include SoftDeletion
after_soft_delete :send_deletion_emails # Rails 2 + 3
set_callback :soft_delete, :after, :prepare_emails # Rails 3
has_many :products
end
# soft delete them including all dependencies that are marked as :destroy, :delete_all, :nullify
user = User.first
user.products.count == 10
user.soft_delete!
user.deleted? # true
# use special with_deleted scope to find them ...
user.reload # ActiveRecord::RecordNotFound
User.with_deleted do
user.reload # there it is ...
user.products.count == 0
end
# soft undelete them all
user.soft_undelete!
user.products.count == 10
TODO
- Rails 3 from with inspiration from https://github.com/JackDanger/permanent_records/blob/master/lib/permanent_records.rb
- maybe stuff from https://github.com/smoku/soft_delete
