Is there a way to provide "sticky" options to ActiveRecord::Base::Find ? I''m thinking something with a use model like: class Function < ActiveRecord::Base sticky :conditions => "lft > 0", :order => "lft ASC" end Where all subsuquent find operations have those options applied. In this case: Function.find(:all) Would actually be equivalent to: Function.find(:all, :conditions => "lft > 0", :order => "lft ASC") And Function....

Anyway, here''s my issue: if I already have a root1 element with lft:1 and rgt:4 (has one child) and add a new root2 (has one child also), it is assigned lft:1 and rgt:4 also!

Is it possible to put conditions relative to the current instance in has_many''s :conditions?

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/.
