Here''s my issue: running ruby -I test test/unit/something_test.rb for each of my unit tests works perfectly. However, running rake test:units brings errors in all of them - some object becomes nil for some reason. Why might this be happening? Specifics: the object that is successfully not nil when I run the unit tests one-by-one but becomes nil when I do rake test:units is defined like

...dered list of ids back to the server after every change, but acts_as_list is designed to deal with diff-like changes, rather than reordering the whole list from scratch. My quick and dirty solution is to @thing_ids = params[:things] @thing_ids.each do |thing_id| Thing.find(thing_id).move_to_bottom end But that''s rather inefficient, and quite slow when you''re ordering large lists. Any better ideas? Tyler

How do I manage multiple lists? This is what I need. Sometimes an item needs to be moved from one list to another. class Item < ActiveRecord::Base belongs_to :group acts_as_list :scope => :group end class Group < ActiveRecord::Base has_many :items, :order => "position" end Now, sometimes, I may need to change an item from one group to another. But when I do that,

only just found the script.aculo.us site. brilliant. much respect. wondered if anyone can point me in the right direction on this drag and drop list re-ordering type thing, i''ve read through what I can but to be honest it''s gone right over my head! How do I get the new order that has been established via dragging list elements around and store them in a database. I figured an

right now i''m adding an item to my ''list'' but i''m unsure how to move it to a certain spot in the list. specifically i want to put it at the bottom of the list. i assumed that if i did something like parent.children << new_child then the ''position'' field in the child table would be given some sensible default by rails but instead

I need an ordered (sortable tree) and I just was thinking if somehting like this is possible: class Item< ActiveRecord::Base acts_as_tree :order => "position" acts_as_list :scope => ''parent_id = #{self.id}'' end For my understanding mixing of two acts_as should be p?ssible, at least in this case, right? Unfortunatly the :scope is not working, I am not
