Strange error(s) on windows only
I have some strange behaviour on Windows XP boxes (the same code on Linux doesn''t have the same behaviour). Ruby 1.8.2 and Rails 0.14.2. I have a single inheritance table nodes with a base class Node (acts_as_tree) and some subclasses such as PageNode and FolderNode. If I render the tree in an iframe in a set of iframes it doesn''t work, if I render it stand alone it works

Ferret slow after a while
I''m building a new index from scratch based on a number of documents stored in a database loaded using my Rails env (using Ruby Ferret 0.9x (installed today with Gem) on Windows). At first everything goes nice but after a number of documents it starts to go slower and slower until it grinds to a halt (at least feels like it). Am I doing something wrong? Is there some way to work

Associated child records not created on creation of a parent.
I am trying to create a record with association. Within the create method, I would also like to pre-populate dependent (has_many) records from a template in the database. The child records are <u>mysteriously rolled back </u> if I insert them in a loop. If I try to insert a single child record, it works.I have read the books and tried to google my way out of this but am at a dead

URL based on acts_as_tree using routes
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,

Using Rails to Generate static pages
Hi all, Has anyone ever thought about or implemented a way to use Rails to pull content from a database and actually *generate* static html pages from view templates? I want to throw a bunch of content into a db using rails and then put all my website templates into the views dir and write the files out with the content inside. The funny thing is that the html pages Rails normally outputs to

eager loading parents and children (acts_as_tree)
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

Why doesn''t acts_as_tree support :scope?
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.

counter_cache is not looking for children_count with acts_as_tree
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

Using set_primary_key breaks acts_as_tree with non-integer column
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 --------------------------------------------------------------------------------------

Many-To-Many w/acts_as_tree?
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

acts_as_tree
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

acts_as_family_tree
For a project that I am working on I need to have a family tree. This means that instead of having one parent each item has at most two. As far as I know acts_as_tree only allows one parent_id. Any suggestions on how to make a "acts_as_family_tree" ? Thanks, Mark -- -------------------------------------------------------------------- I am Mark Daggett and I approve this message.

acts_as_tree with Modified Preorder Traversal?
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.
