I don''t understand something. Consider the following example:
1) parent = Node.create
2) child = Node.create
child.move_to_child_of(parent)
So the tree looks now like:
parent (level=0) => this is the only root node
|
child (level=1)
What instance method do I have to call on the child node to go to the
following structure:
parent (level=0) child (level=0) => now there are two root nodes
So both nodes have become root nodes now. It may look like a strange
situation that a child node would become a root node while it''s old
ancestors don''t move inside the tree. I think it''s a bit like
The
Godfather where one of the caporegimes could start their own family if
they served well. It didn''t happen in the movie though... ;-)
Kind regards,
Mark

Hi Krishna, I''ve reinstalled the betternestedset plugin from the latest development version in the /trunk directory. But I can''t find the method move_to_root (not as an instance or class method) you''re referring to. ./script/plugin install --force svn://rubyforge.org/var/svn/betternestedset/trunk A /home/mark/projects/ruby/mlm/trunk/vendor/plugins/betternestedset A /home/mark/projects/ruby/mlm/trunk/vendor/plugins/betternestedset/test ... A /home/mark/projects/ruby/mlm/trunk/vendor/plugins/betternestedset/README Exported revision 52.

[Betternestedset-talk] child node promoting to root node
Hi Mark, Sorry, I just discovered that method is only in the ez-set branch. Try move_to_left_of or move_to_right_of. Note that you cannot presently move nodes to different trees: you can promote a node to be a virtual root in the present tree, but not the root of a new tree. k On 3/26/07, Mark Noten <mark.noten at itfc.be> wrote:> Hi Krishna, > > I''ve reinstalled the betternestedset plugin from the latest development > version in the /trunk directory.
