Per-Instance Callbacks
Reported by Tom Lea | August 7th, 2008 @ 06:13 PM | in 2.x
This patch allows callbacks to be hooked up on an individual instance.
class SomeStorage
include ActiveSupport::Callbacks
define_callbacks :before_save, :after_save
def save
run_callbacks(:before_save)
puts "- save"
run_callbacks(:after_save)
end
end
store = SomeStorage.new
store.before_save do |object|
puts "saving..."
end
store.after_save do |object|
puts "saved."
end
store.save
#
# Output:
# saving...
# - save
# saved

Hmm, this clashes with the way AR callbacks work... works for none AR apps using ActiveSupport (where the patch was developed), but not so much for Rails...
Ignore the patch.
