Bad values for acts_as_nested_set?
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

acts_as_tree and traversing parent/child relationships
I am working on an Rails application that uses a pretty complex
category structure through out the site. I have defined a table to
house all the info and a FK to reference parents within the table

id int(11) NOT NULL auto_increment,
name varchar(50) NOT NULL,
parent_id int(11) default NULL,

Converting from acts_as_tree to acts_as_nested_set
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.

This is the final list of the new maintainers of each plugin.

Second I will add a note on each rails/plugin mentioning this repos updates.
So from now on, if someone else is interested in helping/contributing
please send a message to the appropriate repo owner.

Being new to Ruby I''m don''t know what enumerator is best to use for
traversing a tree by depth. I can write one, but before I do I wanted
to know if there is there an enumerator for traversing trees available
that the community recommends?
Thank you,

Converting Acts_As_Tree to Acts_As_Nested_Set
Hello,
I have a tree structure that needs to be converted into a nested set.
A great deal of work has already been done on the tree items, so
maintaining the integrity of the id''s is mandatory. However I need
the ability to access entire branches of the tree, which is what
Nested set does. Does anyone have any suggestions on how to
efficiently transfer the tree to the nested set and

acts_as_tree elegant tree printing
Hi,
I''m working with acts_as_tree to print an unordered list of items:
Root
-- Child
---- Child
I''ve got this working, however I''d like to know if there is a more
elegant fashion that I''m unaware of:
#Takes a parent category and recursivley returns all children
def find_all_subcategories(category)
if category.children.size > 0

acts_as_ordered_tree
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

Is acts as nested set safe in a concurrent environment?
Hi I was wondering if acts_as_nested_set can be used safely with
concurrently updates? The fact that so much of the tree needs to be
rewritten on inserts concerns me. Is anyone actually using it. I
noticed that the status of acts_as_nested_set was unclear at the time
the rails book was written.

but I''ve done a hack up job of it. I would like to contribute these
