similar to: Need for multiple acts_as_list

I''d like to announce acts_as_habtm_list plugin for rails. acts_as_habtm_list is a Ruby on Rails plugin, that can manage ordered lists through a join-table. It is providing almost the same Api as acts_as_list. The position column has to be defined in the join table. You can find additional information at: http://www.inlet-media.de/acts_as_habtm_list/ Install it executing this command

Hi all, I am reading a huge data set(12M rows) that contains family information, Offspring, Parent1 and Parent2 Parent1 and parent2 should be in the first column as an offspring before their offspring information. Their parent information (parent1 and parent2) should be set to zero, if unknown. Also the first column should be unique. Here is my sample data set and desired output. fam

This has me scratching my head: a Person has many Things a Person has many Collections a Collection has many Things ...Things in a Collection are ordered ...Things in a Collection can be related to (created by) any User ...a collection has additional attributes, such as a name etc I am confused about habtm in rails (especially when using acts_as_habtm_list) vs. going the :through route.

I''m having trouble trying to get this to work. How the heck do you get a polymorphic controller to work? Especially integrating it with a view? Let''s say that we have shows, and episodes, then comments. A show has many episodes, an episode has many comments. the route is /shows/1/episodes/1/ Now to add a comment to that episode, how would I do it? Let''s say that the

Hello, Is there any way to test model inheritance in spec? something like.. it { ChildModel.should < ParentModel } thanks.

Hi, How are people specifying models which act_as_list? I''m thinking that it would be possible to check that acts_as_list instance methods have been added to a class using something like this: describe Page, "acts_as_list" do it "should act as a list" do Page.ancestors.should be_include(ActiveRecord::Acts::List::InstanceMethods) end it "should use

Hi, If I have a db table categories - id - name - parent_id - position is it alright to have the Category model act_as_tree and for each level act_as_list? class Category < ActiveRecord::Base acts_as_tree :order => :position acts_as_list :scope => :parent_id end Thanks, Peter

So I seem to be having an issue with trying to install acts_as_list in rails 2.2.2? I have downloaded the files from: http://github.com/rails/acts_as_list/tree/master I have put the files in the vendor/plugins folder the files are as follows: vendor/plugins/acts_as_list/init.rb vendor/plugins/acts_as_list/lib/active_record/acts/list.rb vendor/plugins/acts_as_list/test/list_test.rb

Hi, Thest are two methods:- 1) redirect_to :action => ''list'' 2) render :action => ''list'' what is difference between these two methods?????? Thanks. Prash -- Posted via http://www.ruby-forum.com/.

Since I upgraded to 1.1, I am getting ''ActiveRecord::ReadOnlyRecord'' exceptions when trying to save a specific record. I read up on ActiveRecord::Base.readonly? but I don''t think the condition there (objects pulled in from a certain JOIN type) applies. Here''s my code that is throwing the exception: @company = session[:company] @company.bytes_used =

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

Hello everyone! I''ve noticed, that the book uses double quotes almost everywhere. It is like <%= javascript_include_tag "prototype" %> I''ve checked the "programming ruby, 2ed" book and found that double quotes are most suited when escape sequences and substitutions are required. Isn''t it more semantically correct to write this code like

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

Hi, I have 2 models: User and Article. I have this relationship: * User has many articles (and Article belongs to user) * User has and belongs to many articles (and Article habtm users) But this is tricky because of: current_user.articles ...this can return articles thanks to *has_many* and *has_and_belongs_to* relations. So there''s a collision. How can I ask articles thanks

Hi, I have a has_and_belongs_to relationship between 2 objects, order and product. I''m getting a foreign key violation when trying to delete Order. Is there a special way of deleting orders without deleting products? ("has_many" has :dependant => :delete_all.... does "has_and_belongs_to" have something similar) Trying: Order.delete_all Getting: Mysql::Error:

I''m using act_as_paranoid plugin for most of my models. One of the reasons was that I didn''t want to break references between objects after I "deleted" an object. One of the cases was to know which user modified something even after I deleted the user. My problem now is that I cannot access the user after it was deleted if I use the :has_and_belongs_to :user

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

Hi, [reposting to list, posting via google groups apparently didn''t work] I''m trying to use acts_as_list for the first time. Can anyone confirm the odd behaviour reported here? http://blog.nominet.org.uk/tech/Web/2006/03/06/Using_acts_as_list_in_... i.e. element access and move_higher require an odd indexing scheme to work. I''m personally finding that I
