I have a project I''m trying to decide if I want to use rails for. I''m new to rails, so I''m not sure how easy it would be to implement something like this using ActiveRecord. Here''s the situation: Category > subcategory > subcategory > product Category > subcategory > product Some categories will have many subcategories, others few. I want

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

This hopefully is trivial. I am trying to reshape the data using the reshape package. First I read in the data: a2009 <- read.csv("Total2009.dat", header = TRUE) Then I trim it so that it only contains the columns that I have interested in: m2009 <- melt(a2009, id.var=c("DayOfYear","Category","SubCategory","Sku"),

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

I''m working on a simple CMS. The main data type are "listings" a listing habtm (has_and_belongs_to_many) categories and subcategories. Subcategories belong_to categories. Subcategories are basically the same as categories, but they are treated differently in a few situations. The problem is, I can''t seem to write the view/controller/model code that allows me to

I have some data that I read in via read.csv: sales2007 <- read.csv("Total2007.dat", header=TRUE) The data looks like: > sales2007[1:605,] Year DayOfYear Sku Quantity CatId Category SubCategory 1 2007 1 100091 1 10862 HOLIDAY Christmas 2 2007 1 100138 1 11160 PET COSTUMES Famous (Licensed) 3 2007

I have a model, categories, and another model, subcategories. In my current code these have no connection except for the fact that categories has_many subcategories and a subcategory belongs_to a category. But by necessity, I need to change it so Subcategory extends Category; so that I can search both models with one command. I was hoping it would be as simple as changing Subcategory <

Hi, I am having problems with my page. I have a banner and navigation bar in controller_name.rhtml in app/views/layout. Can someone please help?

But when I visit the js file, I got following error Showing

I''ve got a menu in which I have all of my categories as links. Each category also has subcategories. I want to set it up so when you mouse over the category the subcategories will pop up (to the right of the main list, but that''s just CSS). This is what I have so far: <% for category in @categories %> <a href="#"

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 so: Lions

Hi everyone. Sorry if it is not the place to post questions about webgen. I use webgen5, i know it is not the stable version but i couldn''t understand how webgen4 worked, it''s easier with webgen5, and i won''t have to change my pages when it becomes mainstream ;) I try to build my homepage using webgen, and there are some things i don''t know how to do (i am sure

I''m working on a simple photo gallery app for personal use and I want to generalize the sidebar such that in any page (controller or view, I''m not sure which) I can dynamically add either 1. links to a given sidebar 2. or an entire sidebar. I know that typo does this, and I''ve looked the code. I think it''s too complex a solution for my simple site.

I have a user table, and it has forty columns, including name, gender, address, email, phone... So my @user object will have forty attributes. I divide these attributes into 4 groups... namely ''general info'', ''personal info'', ''contact info''... and I make separate forms to edit these 4 different group attributes. The problem is when I update

Hi, I am creating a form that a user can post a message based on his selection on category and subcategory. (A category has many subcategories.)

I have a model, listings. Listings habtm categories and subcategories, which are seperate models.

[I guess were doing top-posting on this sub-thread. Okay, why fight it??] Chris, I didn't know that either. In fact, Sorin answered the question I was thinking of when I posted it. It's really counter-intuitive, even misleading, that "authoring" means burning the DVD... or maybe it means that in the context of DVDs, but means something else in the context of film/video

My main layout includes separate content_for/yield sections for my header, sidebar, footer, and content. However, when running a view spec, the `rendered` variable seems to only contain a string of just the primary content and ignores the header/footer/sidebar as well as the rest of my layout file (the "render" call just returns my primary content wrapped in generic <html> and

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
