I did the following to get Acts as Versioned working:
In application.rb
def self.active_scaffold_controller_for(klass)
# return the correct controller for the versions
begin
if klass.to_s =~ /^.*::Version$/
return klass.to_s.gsub(/::Version
$/,'VersionController').constantize
else
super(klass)
end
rescue => exception
super(klass)
end
end
In my DeviceController:
config.nested.add_link("History", [:versions])
Then I have a device_version_controller.rb:
class DeviceVersionController < ApplicationController
active_scaffold "device/version" do |config|
end
end
You can also do some fancy diff highlighting by updating the
column_class method in the AS lib/helpers/view_helpers.rb. My code
for this is out of date, so I'll leave this up to you to figure out.
