I've been using BNS on my project pretty extensively, it's a 
great plugin, thanks JCM, et al!

 From the maillist archive, it appears there are forks and 
later versions that I can find on Trac? (The only version 
there is 2 years old.)

Sorry for what seems like a dumb question to me, but where
are the latest versions lurking? I have SVN installed, so a 
link to the latest version would be lovely. Thanks! :)

No, see svn for versions, trac misses some updates...
See for instance Krishna enhancements in

Subject: [Betternestedset-talk] multiple trees without a root
Message-ID: <b2d28c010805071221u11be74e3s4f8676bf483093@mail.gmail.com>

Hi,

What would be a better design for this tree. I have Categories of bicycles,
there are a lot more categories than sown. Should I create a root category
as in the Readme file like this. I'll be using these trees for dependent
drop-downs, menus, etc...

Bicycle_Categories
    |
    |_ Road
      |_ Steel
      |_ Titanium
      |_ Carbon Fiber
    |_ Mountain
      |_ Steel
      |_ Aluminum
      |_ Scandium


Or just create independent trees without a main root.

    |_ Road
      |_ Steel
      |_ Titanium
      |_ Carbon Fiber
    |_ Mountain
      |_ Steel
      |_ Aluminum
      |_ Scandium

It always depends. If you NEVER want to show all choices, then
independent trees is probably OK. But I would probably have a single
tree - and then a helper method that lets me get all the first level
children easily. And you may want another helper that would give the
'root' of the subtree, something like 'bike_class' that would return
Road, Mountain, etc.

Subject: [Betternestedset-talk] xml result filtering
Message-ID: <c6fe7cc60805231616y713990b8k53b832396f4f77f7@mail.gmail.com>

in followup to my last email regarding how to use result_to_xml, i was able
to do so, with this syntax:

<%=Match.result_to_xml match.full_set%>

Now, i am wondering how to filter out some of the nodes within my xml. I
only need the id of the match object, not the updated-at and created-at
values that match model includes.

I don't want this:

<match>
    <created-at type="datetime">2008-05-23T16:33:46-06:00</created-at>
 <id type="integer">369</id>
    <updated-at type="datetime">2008-05-23T16:33:46-06:00</updated-at>
    <children>
    </children>
  </match>

I want this:

<match>
 <id type="integer">369</id>
    <children>
    </children>
  </match>



Does this makes sense? i want to trim down my xml result object so that the
object is light weight to go across the wire.


thanks,

jerad

Message-ID: <c12140310805280111i43b48b2aue39afb571938e60c@mail.gmail.com>

Hi all,

I 'm trying to add a node to a tree (tabel has multiple trees).
@node.save
@node.move_to_child_of(1)
# 1 is the id of the parent node

When trying to add the node I get an error:
  SQL (0.000000)   BEGIN

BEGIN

  SQL (0.000000)   Mysql::Error: You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the
right syntax to use near '? ? "root_id IS NULL" : "root_id =
#{root_id}")' at line 1: SELECT max(rgt) AS max_rgt FROM `nodes` WHERE
(root_id.nil? ? "root_id IS NULL" : "root_id = #{root_id}")

  SQL (0.000000)   ROLLBACK

Since I have multiple trees I defined a scope in my node model:
class Node < ActiveRecord::Base
  acts_as_nested_set :scope => :club_id
  has_one :club
  ...


class Club < ActiveRecord::Base
  belongs_to :node
  ...

When I remove this scope I don't get the error.

additional info:
Node table
id-int(11)
club_id-int(11)
parent_id-int(11)
lft-int(11) 			
rgt-int(11) 			
name-varchar(100)

Someone knows what I'm doing wrong?

Regards,
Stijn

Somehow you are getting uninterpreted ruby code in your SQL. I don't
see anything in the code fragments you sent that is setting these
conditions (and then not interpreting them). I would poke around in
the call stack looking for files in your code - or in the
betternestedset plugin to try to find the code fragment above. Then
try to see why it is slapping straight ruby into the SQL query.

I found a simular problem and using up to date code fixed the issue.
