Acts_as_tree help

Hi all…
I created a table having a tree structure using acts_as_tree. Now I
need to access all the parents, grandparents etc upto the root of a
particular node. Also
all the children upto leaf node.
I used particular_node_id.children() method to access the immediate
children
and particular_node_id.ancestors() to access the immediate parents of a
node.

Please help me to find all the parents upto root and all the children
upto leaf of a particular node.

Thanks
Regards
Suneeta

I used this code to get all the ancestors for a given node:

def ancestors(list=[])
if parent.nil?
list << parent
else
list << parent
parent.ancestors(list)
end
list.compact
end

You should use act_as_nested_set or better_nested_set. They are
better optimized for this, and it has built-in methods to accomplish
what you are asking for.
