similar to: AJAX - how to have multiple select form sets implemented?

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

Hello, I am trying to make the "switchover" to programming my apps in Rails and have a question about database structure. In the past i would structure a many to many like this: categories ---------------------------------------------------- | id | name | ---------------------------------------------------- 1 Some Category 2 Another

I''ve got a model, "category" and another model "subcategory." Each subcategory belongs_to a category, and a category has_many subcategories.

Now, I believe this can be done by making

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''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''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

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="#"

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.)

hi guys, I am testing a new optional funtionality in my site with IE 8 after success with Firefox 3.6.3, chrome and safari. The new functionality basically sees a "sub category" drop down list get generated in my form as soon as a "Category" value is selected from the "Category" drop down list. I have been using the standard rails api such as observe_field, and

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 was looking through the docs and couldn''t find a good clean solution for ordering a partial with an :order clause. say i was iterating over categories and thier corresponding sub-categories (regular belongs to) and wanted to order the subcategories according to a certain column; <% for category in @categories %> <% render: partial => ''sublist'',

Hi, I have a date_select in my application and is used to select birth date of authers. So it is quite long list of years in drop down list and seems not practical.

My database is set up as Categories > Things associated by category_id and has_many and belongs_to. How would I go about listing all the categories and under each Category is it''s children?
