similar to: Bad values for acts_as_nested_set?

Hi, I''m trying to get act_as_nested_set working, and I''m puzzled. I googled the following http://codefetch.com/cache?url=http://media.pragprog.com/titles/rails/code/r ails-code.tgz <http://codefetch.com/cache?url=http://media.pragprog.com/titles/rails/code/ rails-code.tgz&path=rails-code/ar/acts_as_nested_set.rb&lang=ruby&qy=ruby>

I''m trying to enhance acts_as_nested_set. Well actually I already have, but I''ve done a hack up job of it. I would like to contribute these enhancements back, but I need a little help. I''m a complete newbie to this stuff. The only thing I new before coming into this project was vanilla HTML. So over the course of two weeks I''ve picked up Ruby, Rails, MySQL,

Hello, I am using acts_as_nested_set. My problem is that the columns "lft" and "rgt" get the value 0 if I create a new entity. If I delete an entity I get negative values (-1, -2, -3) - but for all entities. Is there anything missing? Is there any example for "acts_as_nested_set" in the web? -- Posted via http://www.ruby-forum.com/.

Hi All, I've been working on the GlobalISel combiner recently and I'd like to share the plan for how Combine Rules will be defined in GlobalISel and solicit feedback on it. This email ended up rather long so: TL;DR: We're planning to define GlobalISel Combine Rules using MIR syntax with a few bits glued on to interface with the algorithm and escape into C++ when we need to.

Is there a reason why an ext3 root partition cannot be copied to an alternate partition using the "dd" command? The dd is copying the mounted root partition into an alternate partition that is not mounted. The dd returns success, but the fsck on that partition fails with errors as follows: ----------------- fsck 1.37 (21-Mar-2005) /dev/Active_Update/root2: recovering journal

Dear R-help I am wondering if somebody wrote some code to convert an adjacency list model into a nested set model. In principal I want to do the same as John Celko mentioned it here with SQL: http://groups.google.co.uk/groups?hl=en&lr=lang_en&selm=8j0n05%24n31%241 %40nnrp1.deja.com Assume you have a tree structure like this Albert / \ /

Hi, I'm using ext3 filesystems in embedded devices (storage is on 512Mb or 1Gb CF cards). A typical development cycle would see the filesystem created on the desktop PC running linux 2.4 (eg. RedHat 9). The CF card would be installed in the hardware and linux 2.4 (eg. Montavista Pro 3.1, on PPC) would boot from the CF. Recently I tried a linux 2.6 desktop (CentOS) for the same task and

Does anyone know how anaconda partitioning enumerates disk partitions when specified in kickstart? I quickly browsed through the anaconda installer source on github but didn't see the relevant bits. I'm using the centOS 6.10 anaconda installer. Somehow I am ending up with my swap partition on sda1, /boot on sda2, and root on sda3. for $REASONS I want /boot to be the partition #1 (sda1)

Is it possible to put conditions relative to the current instance in has_many''s :conditions? For example, in a forum app: class Post < ActiveRecord::Base belongs_to :topic has_many :self_and_descendants, :class_name => "Post", :order => "lft", :conditions => "topic_id = #{topic_id} AND (lft BETWEEN #{lft} AND #{rgt})" end With the
