similar to: sorting on a habtm relationship

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

Hello, I''m stuck, I''ve got a model Product and would like to add a new model called Category. Furthermore, I want to set up a many2many relationship between the mentioned models. the problem is that I do not know how to set the primary key in the categories_products table. this is what I''ve got in my migration file: create_table :categories do |t| t.column :name,

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.

This may have been asked/answered before - if so, i apologise... I have the following table layout in a habtm relationship: ------------ ----------------------- -------------- | products | ----| categories_products |-----| categories | ------------ ----------------------- -------------- What would be the best way to pull out all the products for a given category? At the

Hi, I am trying to restrict duplicate has_and_belongs_to_many associations. I tried to find support for a association validation for duplicates but couldn''t find anything. I understand I could use :uniq=>true on the model association but this would only prevent it from displaying duplicates, I want to stop duplicate associations being inserted in the first place. I have a vague

I don''t think this needs much explanation. Is what I''m trying to do even possible? class CreateLanguagesProducts < ActiveRecord::Migration create_table languages_products do |t| t.column :language_id, :integer t.column :product_id, :integer t.column :language_position, :integer end end class Language < ActiveRecord::Base acts_as_list :scope =>

The AWDwR book has the following: add_index :categories_products, [:product_id, :category_id] add_index :categories_products, :category_id The first, composite index actually serves two purposes: it creates an index which can be searched on both foreign key columns, and with most databases it also creates an index that enables fast lookup by the product id. The second index then completes

Hi, I am interested in has_and_belongs_to_many with an acts_as_list relationship where the position field is in the join table. I found the following tutorial http://wiki.rubyonrails.org/rails/pages/HowToUseActsAsListWithHasAndBelongsToMany Is there a newer way that is less complicated? What about the :through parameter that I read DHH is writing? Is that a reality yet? Thanks, Peter

hey all. I''m trying to set up a many-to-many relationship with products and categories. I''ve got the product model (product.rb) set up: class Product < ActiveRecord::Base has_and_belongs_to_many :categories end and a similar one for category.rb And I''ve got the tables set up -- products, categories, categories_products But when I load, I get: undefined method

I have a model "Childmodel" that belongs_to two other models "Parent1" and "Parent2". "Parent1" "has_many :childmodels, :order => :positionp1" and "Parent2" "has_many :childmodels, :order => :positionp2". i.e. The child is independently positioned within each of its parents. This works fine and gets me the useful

Hello, I have the usual Categories and Products table scenario, mediated by a Categories_Products join table. When I create a new Product and into a given Category, I notice that my join table is not being populated. Shouldn''t the join Categories_Products table be populated?

Question about the list in general: by default, it''s set up so that replies go to the sender, rather than the list. However, on other lists I usually chat on, replies by default generally go to the list. This seems to encourage more discussion. Would it be a good idea to change that default? Or am I just crazy.

I have 2 tables: products and categories. They are both linked by a habtm association. I have a fixture to import all the data in each table but I dont know how to import the data in the categories_products table since that table has no model, so I cant use that code: f = Fixtures.new(Category.connection, # a database connection "categories", # table name

The DoubleRenderError exception recently introduced is forcing me to go back and rewrite my apps authentication handler. Before I could do a redirect right in the middle of a request. Whatever was happening after that went unnoticed, I assumed it was simply ending the request after the redirect was called, but apparently it was going on and rendering the page. Why can''t a redirect

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 ! There must be something I don''t understand clearly in acts_as_list I have a list of gallery entries (images + text), model is GalleryEntry. I have a field in_exhibition (boolean) I want the list to be sorted with a scope on in_exhibition : from 1 to N for every record having in_exhibition = false and 1 to N for every record having in_exhibition = true When I use acts_as_list

I am trying to install acts_as_list in a rails 2.2.2 project but when I try the following: ruby script/plugin install acts_as_list I get: Plugin not found: ["acts_as_list"] I had to download the acts_as_list plugin from the github because it isn''t included in Rails 2.2.2. The files are in my vendor/plugins/acts_as_list folder so I have: lib/active_record/acts/list.rb

All, I had been working on a project that was using STI to a very high degree. It also was using a HABTM table that had a couple extra attributes. It seems that with 1.1 push_with_attributes is deprecated and I am having a bit of trouble moving things to using has_many :through The original schema I had worked like this : create_table "nodes" do |t| t.column "title",

Hi, I am trying to perform a query with ActiveRecord that I want to put into a Rails application later. For now I just wrote it within a plain old Ruby script for easier testing. I am working with an existing database so I had to map some foreign keys myself. As you can see from the models below, the database has a structure of Prospectlists <=habtm=> Contacts <=habtm=> Accounts

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
