From 01b1a8772928fbf31180341356981b95d0581413 Mon Sep 17 00:00:00 2001 From: David Heinemeier Hansson Date: Sun, 29 Jan 2006 00:37:39 +0000 Subject: Added reusable reloading support through the inclusion of the Relodable module that all subclasses of ActiveRecord::Base, ActiveRecord::Observer, ActiveController::Base, and ActionMailer::Base automatically gets [DHH]. Added auto-loading support for classes in modules, so Conductor::Migration will look for conductor/migration.rb and Conductor::Database::Settings will look for conductor/database/settings.rb [Nicholas Seckar]. Refactored extensions to module, class, and object in active support [DHH] git-svn-id: http://svn-commit.rubyonrails.org/rails/trunk@3493 5ecf4fe2-1ee6-0310-87b1-e25e094e27de --- .../lib/active_support/core_ext/class/removal.rb | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 activesupport/lib/active_support/core_ext/class/removal.rb (limited to 'activesupport/lib/active_support/core_ext/class/removal.rb') diff --git a/activesupport/lib/active_support/core_ext/class/removal.rb b/activesupport/lib/active_support/core_ext/class/removal.rb new file mode 100644 index 0000000000..8fc4d728b3 --- /dev/null +++ b/activesupport/lib/active_support/core_ext/class/removal.rb @@ -0,0 +1,21 @@ +class Class #:nodoc: + def remove_subclasses + Object.remove_subclasses_of(self) + end + + def subclasses + Object.subclasses_of(self).map { |o| o.to_s } + end + + def remove_class(klass) + if klass.to_s.include?
