I want to implement a unique category tree per user in my system, and I was hoping to use "acts_as_tree" on my category model. It seems as if acts_as_tree makes the assumption that the entire table the model is off of is one large tree. I actually want each user to have their own category trees all stored in the category table so I need it to scope off of the user_id.

So I have the following model class Topic < ActiveRecord::Base belongs_to :topic has_many :topics, :order => :position acts_as_tree :order => :position acts_as_list :scope => :topic_id end that I use for a site''s navigation. Everything (list, create, edit, even the drag&drop sort) works fine, except the destroy function, which the vanilla version def destroy

Hi there, the acts_as_tree API says that I can set a counter cache and that it will automatically increment the "children_count" column. I did that but when I create a new page it asks for a "pages_count" column instead. Here is the relevant part of page.rb model: class Page < ActiveRecord::Base acts_as_tree :order => :position, :counter_cache => true

Any jQuery users out there? I would like to learn more about incorporating jQuery with Rails as the performance seems to be the best of any library I''ve seen and it is great in separating the JScript from the HTML. Any suggestions on where to get started? I''ve read this (http://b.lesseverything.com/2006/12/31/making-jquery-and- prototype-play-nice-in-rails) but was looking into

Guys, I''m having a problem getting acts_as_tree working. It seems from the Agile book (p. 255) that acts_as_tree only supports one-to-one record relations, whereas I need many-to-many support. In other words, looking at the picture at the top of page 256 where where only 1 id is linked to 1 parent_id, I need multiple id''s linked to multiple parent_id''s - for

Hi folks, For my app, I needed to modify acts_as_tree (ActiveRecord::Acts::Tree) such that deleting a node would orphan sub-nodes, rather than deleting them. This is accomplished simply by allowing a :dependent option to the acts_as_tree method so that it can be set to :nullify. For my app, I simply did this by adding a file tree.rb to my lib directory and requiring it in the model. A number

Has anyone extended Rails''s acts_as_tree to use the Modified Preorder Traversal algorithm? This is a really clever trick for optimizing access to trees stored in databases, as described lucidly in this article: http://www.sitepoint.com/article/hierarchical-data-database/2 It adds two integer fields, a "left counter" and "right counter", to each row. By

Using acts_as_tree, is it possible to get information of the depth a tree leaf in relation to the root?

Hi, If I have a db table categories - id - name - parent_id - position is it alright to have the Category model act_as_tree and for each level act_as_list? class Category < ActiveRecord::Base acts_as_tree :order => :position acts_as_list :scope => :parent_id end Thanks, Peter
