Hi There! I''d like some feedback before I try to implement some funky rails routes based on an acts_as_tree model. I have a Page model that acts_as_tree. I''d like the URLs to look something like this: http://localhost/about-us/staff/jeff or, another example... http://localhost/what-we-do/products/our-great-cms/features/faqs/ So, as many sub-nodes the user creates,

hi, im using acts_as_tree and im not sure on how to group find-result. x = find.almost_all <p> <% for y in @x.ancestors.reverse %> <%= link_to h(y.title), page %> &gt; <% end %> </p> gives me a nice "breadcrum". but how is it possible to group the list lets say by the 1level or second level? thx -- You received this message because you are

I''ve got an acts_as_tree structure which I want to be able to represent in the URL, with one field identified as the url component. In other words, if I''ve got this: def self.up create_table :nodes do |t| t.column :parent_id, :integer t.column :tag, :string end end and class Node < ActiveRecord::Base acts_as_tree end and what I want the urls to be is something

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.

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

I am struggling with how to do eager loading of an acts_as_tree model. If the model Stuff acts_as_tree I know I can do this to get children as well: Stuff.find(:all, :include => :children) But what if the model I am including is the one that acts_as_tree? For example, say Picture belongs_to Category. Category acts_as_tree and I want to get all pictures that are members of a category that

Hi, I''m trying to implement a very simple acts_as_tree search in my index html. I am able to show the parents, with no issue, but the children will not show. I have something like this for the parent, which displays fine: <% for group in Group.roots %> <td> <tr> <a href="#" onclick="Effect.BlindDown(''show_<%=

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

i have acts_as_tree installed as plugin under rails 2.0.2 and also its defined in class TreeItems, but when i put this in my view <ul class="tree_level1" id="cars">Furniture <% TreeItem.root.category.children do |cat_children| %> <li><a class="list_item" href="#"><%=h cat_children.name %></a></ li> <%

Hello all, I''m having trouble using acts_as_list with acts_as_tree to order the "children". I''ve found a few old posts on the web that seem to indicate that this once worked. class Whatever < ActiveRecord::Base acts_as_tree :order => :position acts_as_list :scope => :parent_id Although the ''position'' field is being populated, it appears

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

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

Hello people on rails, I am developing a web interface for a database that has hierarchical data. I want the user to be able to browse the tree (~1300 nodes) and activate/deactivate and showing/hiding groups of nodes (like selecting one node selects all the children and the leafs). So I have a tree of objects (ActiveRecord acts_as_tree). Because I need the tree to be persistent and I

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 --------------------------------------------------------------------------------------

Hello Railslist, I want to draw a simple single-table Acts_as_tree model. I''ve read some articles about it and read the API docs, and now I''ve got this running: in controller I have: --- def index @pages = Page.find(:all) end --- in the model for Page I have ofcourse: --- acts_as_tree :order => "position" --- in the helper I have; --- def

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

I''m sure this is really obvious but I''m feeling my way here with rails (and Ruby) and have tried a couple of things without success. So, can anyone tell me the best way to reverse order the retuen list of ancestors. In the controller I have: @ancestors = @category.ancestors which returns an array starting at the parent and ending with the root. When I then loop through the

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
