Hi, has anyone successfully used the acts_as_threaded plugin with postgresql? I''m using rails 1.0 and ruby 1.8.4 on linux. Following the screencast on http://www.railtie.net/articles/2006/02/05/rails-acts_as_threaded-plugin , I got to where we''re ready to create our first post, having made the changes to controllers/posts_controller.rb, views/posts/_form.rhtml,

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 wrap my caffeine soaked brain around has_many :through following along at: http://rails.techno-weenie.net/tip/2005/12/23/teaching_your_blog_model_new_tricks_with_has_many_through I think my models are a little more complex than what fits this narrative. I have a directory of members, each member can belong to multiple categories. The category table references itself

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,

I''m currently using acts_as_tree to display threaded Comments on my forums-like site. It''s waaay too slow to display a page with 1,000 comments, as it''s issuing a TON of selects. I''m pretty sure I want to convert to the nested set model, using acts_as_nested_set or acts_as_threaded. This should give me the performance I''m looking for. The problem,

I am creating forum application which needs usage of acts_as_list or acts_as_tree or acts_as_nested_set. I am unable to decide among these. please could some one recommend from their experience? -- Posted via http://www.ruby-forum.com/.

I moved from acts_as_tree to acts_as_nested_set because I need the all_children method. I''ve seen an alternative way to add this method to acts_as_tree here: http://www.chuckvose.com/articles/2006/05/24/recursive-children But I''d prefer to use the more efficient way of acts_as_nested_set (and not to have to revert to my old code). Anyway, here''s my issue: if I

Hi everybody, I'm mirroring some websites with rsync (daemon on the source), and I noticed in the destination host some error messages 'send_files failed to open filenames', Actually, the concerned files are deleted on the source host, but I would like to ask : * why does rsync say these (in which phase) ? * is these messages harmful or not ? Here below my rsync command and some

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 / \ /

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

Hi, I''m trying to use counter caching in a tree structure (in this case Bob Silva''s threaded list). This is the definition: class Folder < ActiveRecord::Base acts_as_threaded has_many :files end I would like each parent to have the total count of all the childrens member. So when inserting a new file I update the file_count following the parent_id through all the

The recent refactoring didn't work properly for new smart pools, so I've cleaned jup the parameter handling for the various pool 'create' actions.

Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

Don't assume every disk <Item> has a <Parent> field. For floppy disks this is not the case.

hello guys, I have following structure of the table, where I store items of tree: | id | int(11) | NO | PRI | NULL | auto_increment | | user_id | int(11) | YES | | NULL | | | parent_id | int(11) | YES | | NULL | | | lft | int(11) | YES | | NULL | | | rgt | int(11) | YES

I just switched from using the standard "id" column into using my own primary key and generating my own unique id for each record. But, this breaks acts_as_tree. Because my new primary key is not an integer, it breaks the SQL query as follows: StatementInvalid in PagesController#create --------------------------------------------------------------------------------------

Here''s a request string which has a value I want to pull out from the category array - parent_id. Parameters: {"category"=>{"name"=>"Condiments", "parent_id"=>"1"}, "commit"=>"Create"} How do I reference that subelement in the receiving script? I''ve tried params[:parent_id]

I need an ordered (sortable tree) and I just was thinking if somehting like this is possible: class Item< ActiveRecord::Base acts_as_tree :order => "position" acts_as_list :scope => ''parent_id = #{self.id}'' end For my understanding mixing of two acts_as should be p?ssible, at least in this case, right? Unfortunatly the :scope is not working, I am not

Man my app is causing me so much grief lately. Okay let''s say I have: class Discussion has_many :posts end class Post belongs_to :discussion acts_as_tree end Then let''s say I grab a discussion object and try to eager load all of its posts: discussion = Discussion.find(:first, :include => [:posts]) Seems simple enough and it grabs an entire tree of posts. However:

Hi, I''m using the latest gem version of rails under MacOS Tiger. I was trying to use acts_as_tree as described in the rails book. So I have something like: class Category < ActiveRecord::Base acts_as_tree :order => "title" end create table categories ( id int not null auto_increment, title
