Rails - Feb 2006 - acts as nested set

Hi Railers,

Is the nested set model restricted to only one root?

I''m working on a screencast building a threaded forum and nested set
comes
close but is lacking a few items for this project.

First, all the documentation I can find restricts a nested_set to one root
node, and a threaded forum would have many roots. Also, without a ton of
fancy sql or an ungodly amount of db calls, it doesn''t track the depth.

Is my understanding of nested sets correct?

I created an acts_as_threaded to get around these "limitations" which
performs well for this scenario, just curious if nested_set could also have
been used if I had a better understanding of it.

Thanks

Hi Bob,

I''m currently working with acts_as_nested_set too; I''ve
applied all known
patches on dev.rubyonrails.com, which makes it far more usable. Although
it''s still limited to one root, if you setup a level column, it is able
to track
depth easily.

I''m interested in your approach. Could you post your code somewhere?

Regards,

Fabien
