search for: categories

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 => "category").map {|cat| [cat.category, cat.category]}) %> I used [[cat.category, cat.catego...

Hi, I have a small blog application, and I would like to shorten its routes.

hi, there :) Consider a blogging application whereby a user is trying to add a new blog. He/she has to select a category. Upon selecting a category from a drop down box, a new sub categories drop down box will be created (hence an AJAX call). Got this implemented and it''s ok. Now, let''s assume that a given blog can have multiple categories (and subcategories). For example, a blog on a restaurant review can belong to the following categories & subcategories: 1) &...

Hi, I have two models: category and subcategory. (one to many relationship), and a controller ''home'' I''d like to display all the categories and their sub categories in the view: home\index.rhtml. I have a method in the ''home'' controller'' like this: def list_categories @categories = Category.find(:all) end This list all the categories on a view, but I don''t know how to get all the sub categorie...

I''m writing a simple CMS where every item ("listing") HABTM categories and subcategories (which themselves belong_to a category). What I''m trying to do now is create a UI effect for listing creation: when you go to create a listing, only the possible categories will be shown, but when you select a category a set of new categories will be displayed like s...

I''m having some trouble with an instance variable being read as nil in my app. I have an image uploading, that can be added to categories. The page loads up initially fine, and if I upload an image without errors everything works fine. I''m working on the validation, but with the code I have if their are validation errors it renders ''new'' again, but reads @categories as nil and errors out. In render :a...

Hello, sorry for the bulk question, but I cannot find answer anywhere, I have model like Phonebook::Category, and i`m stuck on calling find() method on this model ?

Dear R-users, I want to fit a linear model with Y as response variable and X a categorical variable (with 4 categories), with the aim of comparing the basal category of X (category=1) with category 4. Unfortunately, there is another categorical variable with 2 categories which interact with x and I have to include it, so my model is s "reg3: Y=x*x3". Using fit.contrast to make the contrast (category 1 vs...

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 Subcategory a subclass of Category. Am I right? Unfortunately, there''s...

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:

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 category model I have "belongs_to :posting". That part I ''believe'' is correct, however I very well could be o...

I have a database with a field called ''category''. ''category'' contains the categories separated by a "," i.e. 1, 2, 5 I know with something like: @products = Product.find(:all, :condition => "category = ''1''") I could get some results if any of the ''category'' fields only contained "1" but most contain multiple v...

I have categories and sub-categories in a table called "categories". Every row has a "parent" field to note if the entry is the sub-category of another (never goes deeper than 1 level). So there might be something like this: id | name | parent 1 Dog 0 2 Pug 1 3 Siames...

I really hope this is not a bad question (as in he''s abusing the list). However I could use a little direction (even though I''m reading books, tutorials) Right now I''m getting a undefined method `category'' for 4:Fixnum The specific lines from the rhtml file are: <td><%= link_to position.category_id.category, :action => "show", :id =>

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 column i...

Is it possible to override has_many''s :order attribute at run-time? e.g. something like: <% for category in @site.categories(:order=>''name'') %> ... <% for category in @site.categories(:order=>''rank'') %> ... thanks csn -- Posted via http://www.ruby-forum.com/.

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", :text t.column "answer", :text t.column "product_id", :integer t.column "category_id", :integ...

Hi, I''m using the latest gem version of rails under MacOS Tiger. I was trying to use acts_as_tree as described in the rails book.
