...like they''re designed to mesh well. The ajax sortable lists post a complete ordered 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

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

I have a User model and a Thing model. I want to link users with things, so I have a migration that creates a permissions table with user_id and thing_id. The migration works fine and gives me three columns, I assume I need the permission''s ID so that I can delete it in future. Three questions come to mind though, which I have given thought but got nowhere. 1) Does the

Ok, David says on page 241 that sometimes a many-to-many relation with attributes are better implemented as an actual model instead of using HABTM. Well, I''ve got that situation and I can''t figure it out. All of the examples in the book have HABTM examples between 2 different tables, but I want to have a HABTM relation on 1 table with itself. (e.g., if I have a table Things,

I''d like to use :through to create a web of associations like: class Thing < ActiveRecord::Base has_many :child_things, :through => :thing_thing has_many :parent_things, :through => :thing_thing, :some_other_option? end class ThingThing < ActiveRecord::Base belongs_to :thing belongs_to :child_thing, :class_name => ''Thing'', :foreign_key =>

Is there such a thing? I am thinking of an application that has something like this: 1. person has many things - there is a ''persons'' table 2. the things he has are stored in a table that is something like this person_id, thing_table_name, thing_id For example, it may map to person1, books, 23 #Person 1 owns book 23 person1, books, 25 #Person 1 owns book 25

Suppose I have a multiple select form on an initial page called things[], and two target actions. The initial page submits to target action 1, and target view 1 submits to target action 2. When I submit the form on the initial page, I can access that set of values in target action 1 and turn it into an array of objects by doing something like this (assuming that the option values are object ids,

Let''s start with an example: --- class Comment < ActiveRecord::Base end # dummy (to invent a "table namespace") class Review < ActiveRecord::Base end # ... dummy # is "review_comments" in the database class Review::Comment < ActiveRecord::Base belongs_to :thing end class Review::Thing < ActiveRecord::Base has_many :comments, :class_name =>

First off, hi, I''m [obviously] new :O) Please excuse my question as I''m sure it''s been answered, but I can''t find it anywhere. I have a table of categories: id name 1 Foo 2 Bar I have things which belong_to categories: id category_id subject date 1 1 my subject 07/09/2004 and Further classifications which belong_to categories: id category_id name 1 1 More

Hello everbody, doing a #find(:first,an_id) with Rails 1.1.0 I expected that find returns the record which id mathches the given parameter an_id or nil if it couldn''t be found. This behaviour is documented on api.rubyonrails.org. But the find returns the first available object and not nil if an_id is not in the db. Is the doc on rubyonrails.org out of sync?
