Hi all, I have two controllers - "foods" and "receipes" which map to models. Each one will have multiple categories, but the categories are completely different for each one - they don''t share the same category. So they aren''t related at all. If I wanted to do this using resources, what is the best way to set this up? If I setup a categories controller and

I''m trying to wrap my caffeine soaked brain around has_many :through following along at: http://rails.techno-weenie.net/tip/2005/12/23/teaching_your_blog_model_new_tricks_with_has_many_through I think my models are a little more complex than what fits this narrative. I have a directory of members, each member can belong to multiple categories. The category table references itself

Hi, I''m starting to build a simple (?!) FAQ system, and I''d like some advice on setting up the model relationships. I was going to go with a simple system of a Category table and a FAQ table (holding questions and answers) - where one FAQ belongs to one category. That''s all nice - a simple has_many / belongs_to relationship. Then I decided to add another level - Area.

Hi there, I''ve been working on this for awhile and have finally decided to ask for a little guidance.I have a slight problem trying to save a selection. I have two models: A "Posting" has_many "Categories", and a "Category" belongs_to one "Posting". With that said, in the posting model I have "has_many :categories" and within the

Let''s say I have a catalog with hotels. Each hotel belongs to a category (4-star, 5-star etc.) This is it''s official category.However, there is also a category that users assign and a category that "independent reviewers" assign. So I have this: hotels { id, category_id, reviewer_category, user_category } categories { id, name } class Hotel <

Hello guys, I''m a newbie in RoR and I have a problem. My DB structure is ====================================== topics table : id(int,11) name(varchar,255) categories : id (int,11) topic_id(varchar,255) name(varchar,255) ====================================== --Models:-- class Topic < ActiveRecord::Base has_many :categories end class

Can someone clarify this for me? Suppose I have two tables like: class Company < ActiveRecord::Base belongs_to :category end class Category < ActiveRecord::Base has_many :companies end I understand that the belongs_to causes related companies to be read from the db when I ask for a category. I suspect SQL something like select * from categories, companies where category.id

I''m new in Rails, and I''m building my first application. I''m trying to make a FAQ for this application, organized by product (questions about each product) and category (questions of different categories or topics), and there is something I can''t figure it out how to do. I have these tables: create_table "faqs" do |t| t.column "question",

This works : class Recipe < ActiveRecord::Base belongs_to :category end But (when I add validation) this does not work : class Recipe < ActiveRecord::Base belongs_to :category validates_length_of :category, :within => 6..20 validates_uniqueness_of :category, :message => "already exists" end thank you -- View this message in context:

I am using Ferret and acts_as_ferret, as my search back-end for my Rails project. I have a question about using acts_as_ferret on a main table that is linked to other tables by foreign keys. Is there a way to include the information linked by the belongs_to keyword in the search results ? As an example, let''s say I have a main table ''posts'':

Ahoy, I was able to follow the tutorials and build a simple to-do list program with Items and Categories and have the related tables link up w/ the default "scaffold :Items" command plus custom defenitions. Then I erased all of that and tried rebuilding the program using the ruby script/generate scaffold Item (and category) command. Now the templates look like " <% for

I''ve got a model, "category" and another model "subcategory." Each subcategory belongs_to a category, and a category has_many subcategories. What I need to do is set it up so that I can search Category and Subcategory with one .find call. So: Category.find(:all, <etc) will find categories and subcategories. Now, I believe this can be done by making

Basically, I''m trying to have a table called "categories" have a many to many relationship with itself. But I also want each catagory to be able to be "copied" into another category so it is essentially a child category to more than one parent. To me the obvious way of doing this is by creating another table called category_maps (and a model called CategoryMap).

Consider the following scenario: Book has_and_belong_to_many Category. In other words, a category may have a lot of books, and a book can have more than one category. What is the best practice to query all books related to some specified categories. For example, if I have following books "From Java To Ruby" - Category: Java, Ruby "Ruby Programming" - Category: Ruby

Just when I started getting the hang of has_and_belongs_to_many relationships, I realize that I should probably convert several of my app''s joins to has_many :through type relationships. One example, pairing users with categories via subscriptions, where each user can be the "owner" of a category, has given me particular trouble when I try to update a user''s

i think there ara two ways of relate products and categories , basically i want to fix one product(e.g hp dv7....) to some categories (notebook,17"notebooks...) i made a table named categorization(incuding category_id,product_id fields) then in models i write these codes below class Product < ActiveRecord::Base has_many :categories, :through => :categorizations

1. A category has parent categories. 2. A product is in many categories and a category has many products. 3. Products and category both have images in the same image table. ie. a product and / or category could have multiple images.<=== my question is related to this So among other things I presume I have to do the following: class Category < ActiveRecord:Base #...

I''ve tried pulling this together from examples in the book, searching the web and this list, but so far I''ve not been able to get it working just right. My table is a categories table with id and category fields. My form has the following: <td><%= select(''category'', ''category'', @categories = Category.find(:all, :order =>

I''m building a simple support ticket system for use in our office. I''ve got a model called Ticket and one called Category and I''m trying to set it up so that I can add categories at will and assign many categories to a single ticket. I''m trying to use the has_many :through association to accomplish this, but I''ve run into an issue. Here''s
