class Page < ActiveRecord::Base has_many :lists end class List < ActiveRecord::Base belongs_to :page end ######### controller code, inside action: list = List.find(params[:id]) old_page = list.page list.page = new_page # what is the value of old_page now? old_page now is the same as new_page! what the heck?!? The only thing i can think of is that old_page is getting assigned some kind of proxy object, rather than the Page object itself, and "list.page = new_page" changes only the actual Page obj...

hi book and page is one_to_many relationship.I want to create them in a single form.But when clicking create button,the submitted params for pages are not grouped correctly, i want "book"=>{"new_pages"=>[{"name"=>"", "color"=>""}, {"name"=>"","color"=>""}] but it is "book"=>{"new_pages"=>[{"name"=>""}, {"name"=>"", "col...

Hi all, this series removes most users of the write_one_page API. These helpers internally call ->writepage which we are gradually removing from the kernel. Changes since v2: - more minix error handling fixes Changes since v1: - drop the btrfs changes (queue up in the btrfs tree) - drop the finaly move to jfs (can't be done without the btrfs patches) - fix the existing minix code to

Greetings, after Carsten pitched CMM2 on the kvm mini summit here is a repost of version 5 of the guest page hinting patches. The code is still the same but has been adapted to the latest git level. -- blue skies, Martin. "Reality continues to ruin my life." - Calvin.

After way to many months here is the fifth version of the guest page hinting patches. Compared to version four a few improvements have been added: - Avoid page_host_discards() calls outside of page-states.h - The discard list is now implemented via the page_free_discarded hook and architecture specific code. - PG_state_change page flag has been replaced with architecture specficic
