# mongoid-paranoia [![Build Status](https://travis-ci.org/haihappen/mongoid-paranoia.png)](https://travis-ci.org/haihappen/mongoid-paranoia)

**Important:** This gem is an extraction of [Mongoid::Paranoia](http://mongoid.github.io/en/mongoid/docs/extras.html#paranoia) from the official [mongoid](http://mongoid.org) gem.
Since Mongoid::Paranoia was removed in the `4.0.0` release of Mongoid, this gem re-enables the functionality of paranoid documents.

**Please submit only bug and security fixes**. Neither I will accept new features nor changes to existing APIs.

**Attention:** There are two similarly named gems out there: `mongoid-paranoia` and `mongoid_paranoia`

* `mongoid-paranoia`'s (this one) goal is to stay API compatible, which comes at the cost of (breaking) API changes to be rejected. If you're updating a Mongoid 3.x app to Mongoid 4+ and you depend on `Mongoid::Paranoia` this gem is recommended for continuity.

* However if your code is working and you want new features, for example a `*_restore` callback, you should head over to @simi's `mongoid_paranoia` gem at https://github.com/simi/mongoid_paranoia. He is doing a great job there and is willing to accept your PRs ;)

There may be times when you don't want documents to actually get deleted from the database, but "flagged" as deleted. Mongoid provides a Paranoia module to give you just that.

## Installation

In your Gemfile:

```ruby
gem 'mongoid-paranoia'
```

## Usage

```ruby
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.
```

The documents that have been "flagged" as deleted (soft deleted) can be accessed at any time by calling the deleted class method on the class.

```ruby
Person.deleted # Returns documents that have been "flagged" as deleted.
```
