Not sure yet.
I’ve added a simple tree via ActiveScaffold then tried to get back data.
With this code all_children method returns nil, children method returns all fine…
1 2 3 4 5 6 7 8 9 | roots = Help.roots roots.each do |r| @s += r.level.to_s + ' | ' + r.name + ' | ' + r.children_count.to_s childset = r.all_children childset.each do |ch| @s += ch.name end end |
Then I found that BetterNestedSet cannot handle multiple roots in a table unless there is a new column added to the schema. In plus ActiveScaffold cannot simply move a children to another parent as simple as in acts_as_tree.
Later I’ve found that the official plugin page is deprecated (so RadRails installed automatically an older version of the plugin) , and you should look for the right version at RubyForge instead.
After all these, spending 1 day with BetterNestedSet and found heavier to use & less documented than the simple acts_as_tree I switched back to the plain old solution.
