similar to: acts_as_list with scope : position update problem?

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,

I''d like to be able to use a has_many :through association and treat the associations as a list but I''m getting this error when I try an use an acts_as_list method: NoMethodError: undefined method `move_to_bottom'' I''m using edge rails r6786. Here are my domain rules: Activities are things students can do. Units consists of a sequenced list of

First, BRAVO for this wonderful plugin: has_many_polymorphs ! Now my problem: 4 models : Collection, Page, Fragment, Belonging (which is the join table): 1 class Collection < ActiveRecord::Base 2 has_many_polymorphs :elements, 3 :through => :belongings, 4 :from => [:pages, :fragments, :collections], 5 :as => :collector, 6 :parent_order =>

Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

I''m trying to figure out a good way to get acts_as_list and the new sortable lists to play nicely together, but they don''t seem 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

Hi R users. sorry for missing example and if question is to general but I am wondering if it is possible to execute subqueries in function sqlQuery (package RODBC) with opened connection with Excel or SQL server 2000. I couldn't find any example of this. And if it is possible what should be a correct syntax for this query: SELECT ct,COUNT(*) as n FROM (SELECT COUNT(*) AS ct FROM children

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

Hello, I''m running a Rails application which must sort and manipulate a lot of data which are loaded in memory. The Rails app runs on 2 mongrel processes. When I first load the app, both are 32Mb in memory. After some days, both are between 200Mb and 300Mb. My question is : is there some kind of garbage collector in Mongrel? I never see the two Mongrel processes memory footprint

Hi, My local server is running CentOS 7. The machine has two NICs and is acting as a gateway. For DHCP and DNS, I'm using Dnsmasq. I have a strange little problem with local hostname resolution. Before going into more details, here's my configuration. [root at nestor:~] # ifconfig enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.2 netmask

I am doing some very very basic unit testing. If I take away the uniqueness validation, the tests pass.

Hello, On my local machine (Mac OS X 10.5.5), I get the following error when I try to run script/server start : "Rails requires RubyGems >= 1.1.1 (you have 1.0.1). Please `gem update --system` and try again." The Rails app was a former 1.2.6 upgraded to 2.1, and it worked fine. I''ve run the rake rails:update command. If I create a new Rails app, it starts with the command

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

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

in a single table inheritance model, rails will automatically set the scope for acts_as_list to the ''type'' field as well as any other scope conditions we provide. Is there a way to disable this? i want to use STI but I want acts_as_list to disregard the class type when getting/setting positions. thanks alan

Hello all, I''m having trouble using acts_as_list with acts_as_tree to order the "children". I''ve found a few old posts on the web that seem to indicate that this once worked. class Whatever < ActiveRecord::Base acts_as_tree :order => :position acts_as_list :scope => :parent_id Although the ''position'' field is being populated, it appears

Here''s what I''m trying to do: class Model < AR::Base acts_as_list :scope => [:key_one_id, :key_two_id, :key_three_id] end with the idea being that there are these three references from this table (one of them being optional) that define the list. I don''t think acts as nested set works in this situation because I''m still just dealing with a single list

I just installed a newer version of Ubuntu and so with it, rails 2.3.2. Now I can''t get acts_as_list working.
