BTW, if you found this in production code, I'd highly recommend KILLING IT WITH FIRE and using something like will_paginate if at all possible - this is the quite-ancient original pagination code included with Rails (stripped out to the classic_pagination plugin in 1.2.4!) and is immensely inefficient. The Rails version of your code really doesn't matter; I just got will_paginate up and running on an old 1.2.3 app without any major issues. --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
