Hello, I am using acts_as_nested_set. My problem is that the columns "lft" and "rgt" get the value 0 if I create a new entity. If I delete an entity I get negative values (-1, -2, -3) - but for all entities. Is there anything missing? Is there any example for "acts_as_nested_set" in the web? -- Posted via http://www.ruby-forum.com/.

Hello, I have a tree structure that needs to be converted into a nested set. A great deal of work has already been done on the tree items, so maintaining the integrity of the id''s is mandatory. However I need the ability to access entire branches of the tree, which is what Nested set does. Does anyone have any suggestions on how to efficiently transfer the tree to the nested set and

I''m currently using acts_as_tree to display threaded Comments on my forums-like site. It''s waaay too slow to display a page with 1,000 comments, as it''s issuing a TON of selects.

R gurus, Every so often(*) someone asks how to suppress scientific notation in printing, so I thought I'd give it a shot, but I need some help. The formatting decision is made(**) on line 286 of src/main/format.c : if (mF <= *m) { /* IFF it needs less space : "F" (Fixpoint) format */ where mF is the number of characters for "normal" printing and *m is the number

Of course this fails down eventually and does require at least a partial table rewrite (and you''d prob want to do a multiple of more than 10 on the entries to begin with), but it would certainly cut down the probs.
