[Nitro] many_to_many delete bug

[Robert Mela]

Just for reference -- the other showstopper is in 
http://rubyforge.org/pipermail/nitro-general/2007-November/008957.html

The new issue is delete in a many_to_many relation:

Here's code that triggers it.   I tried p.remove_tag(t1) and p.save! 
before the delete -- still no dice.   Even if that did work it'd be a 
workaround, and unintuitive.

#!/opt/local/bin/ruby
require 'og'
require 'sqlite3'

class Post
attr_accessor :name, String
is Taggable
end

Og.start(
:adapter => 'sqlite',
:name => 'tagtest',
:destroy_schema => true,
:create_schema => true
)
p=Post.new
p.name = 'post1'
t1 = Tag.new
t1.name = 'tag1'

puts "Program inserting tag1"
p.tags <<  t1
puts "Program calling save"
p.save!
puts "Deleting tag"
t1.delete
