Betternestedset talk - Apr 2008 - move_to_child_of in after_save Callback

I''m trying to include a move_to_child_of in an after_save callback, but
no
matter how I do it, it seems to error out. Specifically, I''ve got a
attribute named bns_parent_id in my model (and associated field in the
table). I choose to create this field because I''ve been told that BNS
does
like it when you try to mess with it''s reserved fields (parent_id, lft,
and
rgt). I have a field for bns_parent_id in my view (but not for parent_id).
The I have the following in my model:


  def after_save(record)  
    record.move_to_child_of record.bns_parent_id  
  end

I''ve tried multiple permutations of this callback, but they all seem to
error out. Does anyone have any idea how to make this work? (By the way, it
would be great if this or a similar type of functionality was incorporated
into BetterNestedSet.)

you may want to take a look at ez_set (one of the branches in the same
svn repository). it does all the moving for you.
