Mongoid::Paranoia enables a "soft delete" of Mongoid documents.
Instead of being removed from the database, paranoid docs are flagged
with a deleted_at timestamp and are ignored from queries by default.
The Mongoid::Paranoia functionality was originally supported in Mongoid
itself, but was dropped from version 4.0 onwards. This gem was extracted
from the Mongoid 3.0.0-stable branch.
Caution: This repo/gem mongoid_paranoia (underscored) is different than mongoid-paranoia (hyphenated). The goal of mongoid-paranoia (hyphenated) is to stay API compatible and it only accepts security fixes.
- The current release is compatible with Mongoid 7.3 and later, and Ruby 2.7 and later.
- Earlier Mongoid and Ruby versions are supported on earlier releases.
Add this line to your application's Gemfile:
gem 'mongoid_paranoia'class Person
include Mongoid::Document
include Mongoid::Paranoia
end
person.delete # Sets the deleted_at field to the current time, ignoring callbacks.
person.delete! # Permanently deletes the document, ignoring callbacks.
person.destroy # Sets the deleted_at field to the current time, firing callbacks.
person.destroy! # Permanently deletes the document, firing callbacks.
person.restore # Brings the "deleted" document back to life.
person.restore(:recursive => true) # Brings "deleted" associated documents back to life recursivelyThe documents that have been "flagged" as deleted (soft deleted) can be accessed at any time by calling the deleted class method on the class.
Person.deleted # Returns documents that have been "flagged" as deleted.You can also access all documents (both deleted and non-deleted) at any time by using the unscoped class method:
Person.unscoped.all # Returns all documents, both deleted and non-deletedYou can also configure the paranoid field naming on a global basis. Within the context of a Rails app this is done via an initializer.
# config/initializers/mongoid_paranoid.rb
Mongoid::Paranoia.configure do |c|
c.paranoid_field = :myFieldName
endvalidates :title, uniqueness: { conditions: -> { where(deleted_at: nil) } }before_restore, after_restore and around_restore callbacks are added to your model. They work similarly to the before_destroy, after_destroy and around_destroy callbacks.
before_remove, after_remove and around_remove are added to your model. They are called when record is deleted permanently .
