acts_as_active¶ ↑

This plugin override the default behavior of ActiveRecord#destroy method to set an active attribute to false instead of delete the record. The plugin also add a default_scope to hide the inactived records. This plugin assumes the table has a active boolean field, with default to true.

This plugin is HEAVLY influencied by acts_as_paranoid

Instalation¶ ↑

This plugin depends of default_scope, introduced in Rails 2.3. If you use Rails 2.1 or 2.2, install default_scope as a plugin:

script/plugin install git://github.com/duncanbeevers/default_scope.git

After, install this plugin:

script/plugin install git://github.com/fernandoluizao/acts_as_active.git

Example¶ ↑

create_table :users do |t|
  t.string :name
  t.string :last_name
  t.boolean :active, :null => false, :default => true
end

class User
  acts_as_active
end

User.first.destroy
UPDATE users SET active = 'f' WHERE id = 1

User.first.destroy! #call the original destroy
DELETE FROM users WHERE id = 1

User.all
SELECT * FROM users WHERE active = 't'

User.all :conditions => {:name => "joe"}
SELECT * FROM users WHERE (name = 'joe') AND (active = 't')

User.find_with_inactive :conditions => {:name => "joe"}
SELECT * FROM users WHERE (name = 'joe')
