Hi

I’ve been putting together database scripts that rely on Active Record  
outside of rails - this link was very helpful in getting started:  
[http://ollehost.dk/blog/?p=214](http://ollehost.dk/blog/?p=214)

Now though, I’m having a problem getting this to work with  
betternestedset.

Can anyone tell me how to require these nested methods in an external  
script? These don’t seem to pick them up:

require ‘rubygems’  
require ‘active\_record’

My error is:

C:/MyDevelopment/InstantRails/ruby/lib/ruby/gems/1.8/gems/  
activerecord-1.15.3/lib/active\_record/base.rb:1860:in  
`method_missing': undefined method `move\_to\_child\_of’ for  
#Employeetree:0x9466a28 (NoMethodError)

thanks!  
Andrew
