similar to: importing data with migration for habtm

I have two tables ("products" and "categories") that have a has_and_belongs_to_many relationship, and I need to be able to arbitrarily sort products in the scope of a category using something like acts_as_list. Problem is, since each product can belong to multiple categories, it doesn''t work to use acts_as_list and have the "position" field be in the

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 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 all, I woke up at 4AM this morning to find a solution for this and it is still not working.. grrr! lost sleep for nothing! Anyways, I have 2 select list and I want the content of the second list to be updated according to what is selected in the first list. I did this in the past by having my application generate all the possible content of the second list and make some Javascript to do

Hi all, I am having a weird problem reading a value from my model. basicaly, I have these two models: class Category < ActiveRecord::Base acts_as_tree :order => "name" belongs_to :item_type has_many :specific_category_names end and class SpecificCategoryName < ActiveRecord::Base set_table_name "Specific_category_names" has_many :products belongs_to

Hi all, This testing problem has been a sink for time today, and is still unresolved. Basically I have some unit tests that test simple functions (example below) that depend on join operations in a habtm relationship, and I suspect I am getting "false" failures, i.e ones that do not logically make any sense. I need fresh sets of eyes to take a look and see if I''m mising

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

Hi Marek, I had some more thoughts and discussions with Robin about how to make this work with the Exynos driver. The result is the patch below, can you please test it and report back? Even better if you can fix up any breakage it might cause :) >From 60a288509baa34df6a0bf437c977925a0a617c72 Mon Sep 17 00:00:00 2001 From: Joerg Roedel <jroedel at suse.de> Date: Thu, 9 Apr 2020 13:38:18

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

I am a the point now where I have to add user authentification to my application. Anyone can point me toward an easy to use / secure library? I know about ActiveRBAC and was wondering if there is anything else that I should consider. Thanks! -- Posted via http://www.ruby-forum.com/.

Hi, I have a strange problem with testing classes which have a HABTM relation. It seems that while running my tests with rake the fixture for the association table is not loaded - as a result I get a failure on a test which simply checks the number of associated elements - it says it''s 0 although there should be one. The weird thing is that when I run the tests with rcov

I''m resending this with additional information, as I''ve had no response.

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?
