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:

People, I can order categories when looking at the categories list page but how do I change the recipe page to list the categories in alpha order in the recipe pull-down box?: > <p><b>Category:</b><br> > <select name="recipe[category_id]"> > <% @categories.each do |category| %> > <option value="<%= category.id

Still Stumbled on First things in trying RubyOnRails http://www.digitalmediaminute.com/article/1816/top-ruby-on-rails-tutorials http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html http://instantrails.rubyforge.org/tutorial/index.html http://rails.homelinux.org/ I had tried the first of the top 12 tutorials and got stuck after adding a new field ?category_id?in the table recipes,

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 very new to ruby and need to create my first HABTM with multiple select list.  I am having problems saving data in the middle(linking) table.  1. titles can have multiple categories  2. categories can have multiple titles Categories, titles and categories_titles tables are created.  ----- title_controller.rb--   def new     @title = Title.new     @categories =

In my mind, it should work like this: <%= select ''item'', ''category_ids'', Category.find(:all).collect {|c| [c.name, c.id] }, {}, {:multiple=>true, :size=>20} %> Then Rails should automatically populate and update HABTM on that. As it is now, the above won''t work (I created a getter in item''s model that returns an array of

Hi all, New to the list, Ruby, & RoR. I''ve been going through the Rolling With Rails tutorial, but am getting the following error when the instructions tell you to add the @recipes = Recipe.find_all line to the RecipeController: Template is missing Missing template ./script/../config/..//app/views//recipe/index.rhtml The index.rhtml file is right where it''s supposed to

I am a new user to RoR/ I have been working on RoR cookbook2 tutorial which could be found at http://instantrails.rubyforge.org/tutorial/index.html. As I have been going through different stages through trial and error, but now a stage has come that i m stuck and not able to proceed any further. when it comes to create a list.rhtml in recipe folder under views, and editing the code which is

I am please to announce the release of Recipe Browser 0.4.1. This project (and files) can be located at http://rubyforge.org/projects/recipe/.

Special thanks to E Gard (x2egard) the newest member to the project who also happened to do all the work for this release ;). We would love to hear any questions,

I am doing the recipe/category example, but with a has_many_and_belongs_to relationship. To select categories for a recipe, I have a select control. When editing, I want the proper categories selected. In order to get it to work, I put this in my _form.rhtml: <select id="recipe_categories" name="recipe[category_ids][]" size="4" multiple> <%=

Hi there, I have a question on what would be the best way to save a HABTM model. A posting habtm categories, and a category habtm postings. class Category < ActiveRecord::Base has_and_belongs_to_many :postings end class Posting < ActiveRecord::Base has_and_belongs_to_many :categories end In my blog_controller, where the actual posting is saved, is where I think I''m

After *much* digging and playing around, I finally figured out how to unit test instance variables that are created by actions. It was more difficult than I expected. It seems like there should have been a more straight forward way to do this. Can someone enlighten me? A simplified and somewhat contrived example of what I am current doing: Thanks. Matt >> # My Controller of interest

Hi all, I am a newbie to Rails. Please enlighten me on how to do this appropriately, the Rails and the Ruby way: Suppose I have a Recipe model. Let''s simplify things and pretend that it has only 2 attributes, a :name and the other is a ''category_id''. In the recipes table, category_id is a foreign key to field id of table categories. We also assume that I have generate

Hi, Day 3 with rails here. Forgive me. If this has been covered many times before, pls just point me at the article. I worked through the Rolling with Rails tutorial (http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html) built up my cookbook. Things work great. I now want to add Ingredients to my app. So, a Recipe will have 1 or more Ingredients and any single ingredient can be

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

I searched for forum for something about this but couldn''t find anything. For example I have this in my view: (you enter start/end dates from dropdowns, pick a category and a report is generated.) <%= start_form_tag :action => ''display_report'' %> From: <%= date_select ''report'', ''date1'' %> <br /> To: <%=

Hi I''m trying to use restful resources with recipes and ingredients I''ve set up the models using scaffold_resource. A recipe can have many ingredients and an ingredient can be in many recipes. I''ve set the relationships up using a through. I now want to display a recipe with a list of ingredients but I''m unsure how to proceed. Should I use nested resources and

I''m experimenting with Rails on the Recipes example first before I dive into applying it to my intended application. I''m exploring which will be more work: to rename all the primary id''s in the legacy database, or to work around the fact that the primary id''s are not called ''id'' within RoR instead. I''ve been successful in using a

I was brainstorming today about a smooth way to define conditions in an sql query, when the numbers of attributes increase, so does the uglyness. So instead of passing a hash, I thought you could specify the conditions directly in code. I hacked together some example code which actually turned out to work. The result is concise and pretty beutiful. def search(params) Ad.find(:all) do

Hi everyone, I''ve tried posting the same question to the list last Friday but somehow did not see it being posted.. I''ve just started with Rails and Ruby. I just started to play one of those RPG and to get my feet wet I''m writing an app to keep track of item fusions. So the scoop is that item can be fused with another items to create a higher level item. The higher
