Gem Version Build Status

Lite::Archive is a library for archiving (soft-delete) database records.

NOTE: If you are coming from ActiveArchive, please read the port section.

Installation

And then execute:

$ bundle

Or install it yourself as:

$ gem install lite-archive

Table of Contents

Configurations

rails g lite:archive:install will generate the following file: ../config/initalizers/lite_archive.rb

Lite::Archive.configure do |config|
  config.all_records_archivable = false
  config.sync_updated_at = true
end

Usage

An archived_at column must be added to tables where you do not want records destroyed. If the table does not have this column, records will be destroy instead of archived.

class AddArchivedAtColumn < ActiveRecord::Migration
  def change
    create_table :table_name do |t|
      t.timestamp                # Adds archived_at automatically (if all_records_archivable is set to true)
      t.timestamp archive: true  # Adds archived_at timestamp
      t.timestamp archive: false # Does NOT add archived_at timestamp
    end

    add_timestamp :table_name

    add_column :table_name, :archived_at, :datetime # Manual column (null constraint must be false)
  end
end

user.archive        #=> Archives the User record and its dependents
