* A new module (ActiveSupport::Autoload) is provide that extends
autoloading with new behavior.
* All autoloads in modules that have extended ActiveSupport::Autoload
will be eagerly required in threadsafe environments
* Autoloads can optionally leave off the path if the path is the same
as full_constant_name.underscore
* It is possible to specify that a group of autoloads live under an
additional path. For instance, all of ActionDispatch's middlewares
are ActionDispatch::MiddlewareName, but they live under
"action_dispatch/middlewares/middleware_name"
* It is possible to specify that a group of autoloads are all found
at the same path. For instance, a number of exceptions might all
be declared there.
* One consequence of this is that testing-related constants are not
autoloaded. To get the testing helpers for a given component,
require "component_name/test_case". For instance, "action_controller/test_case".
* test_help.rb, which is automatically required by a Rails application's
test helper, requires the test_case.rb for all active components, so
this change will not be disruptive in existing or new applications.
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.delivery_method = ActionMailer::DeliveryMethod::Smtp
we could equally set our own custom object
as long as it provides the instance method :perform_delivery(mail)
eg.
class MySmsDeliveryMethod
def perform_delivery(mail)
Sms.send(mail['to'], mail['body'])
end
end
MySmsMailer.delivery_method = MySmsDeliveryMethod.new
