Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

I am just going through the book and I come across a problem with the code in the app/models: validates_format_of :image_url, :with => %r{^http:.+\.(gif|jpg|png)$}i, :message => "must be a URL for a GIF, JPG, or PNG image" It seems to moan when it''s empty even though I removed :image_url from validates_presence_of. How should I make it optional?

Hi, I just started learning ruby on rails and I am having hard time with white spacing! Here is the piece of code that will not work: validates_format_of :image_url, :with => %r{\.(gif|jpg|png)$}i, :message => "must be a URL for a GIF, JPG or PNG image" and here is the piece of code that will work: validates_format_of :image_url, :with => %r{\.(gif|jpg|png)$}i, :message

Greetings! I''m having a hard time understanding the way Rails handles urls. I''m specifically having real trouble with the image_urls in the Depot app in the Agile Web Development book. If I enter "\image\file.png" in the Add Product page, the image is displayed in the other views and Properties shows http://localhost:3000/images/file.png If I leave off the leading

Hi everyone, I''m working my way thru the ''Depot'' project from Agile Web Development with Rails. I got to the bit where I type: ruby script/generate scaffold Product admin And I get the following error: error Before updating scaffolding from new DB schema, try creating a table for your model (Product) ( on the last line ! ) Now I have followed everything as

I am actually following the instructions/code snippets from "Agile Web Development with Rails" and got as far as page 73 where I did ruby script/generate controller Store index, then edited store_controller.rb to class StoreController < ApplicationController def index @products = Product.salable_items end end and product.rb to: def self.salable_items find(:all,

I am working my way through Agile web development with rails and I''m in the testing chapter. when I run the following test(or any other test) I''m new and not sure where to start looking. require ''test_helper'' class ProductTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end end I

I went throught the "agile web developemnt with rails" and Now I''m trying to ''enhance'' the code with some extra options. When I go to admin/shipping I want to include some data from the products table in with the order info listed. I can''t seem to get this to work. in my partial form I''m trying to add this: <td

I''ve been following along just fine with the depot app, up until I make the catalog, where, when the price is displayed with formatting, the price shows up underneath the <div> bar for the next item in the catalog. If, in index.rhtml, I change the <span class="price"> to just <span>, or equivalently, remove the entire <span...> tag, it works just

Hey, I''ve gotten file_column to upload a file, drop it in the dynamic directory, but I can''t display the image, the directories repeat themselves: My model: class Person < ActiveRecord::Base file_column :image_url In my view: <%= image_tag url_for_file_column(''person'', ''image_url'') %> HTML generated is this: <img

In a model I have following validates_format_of. Is there an easy way to DRY this up? It seems to be rather repetitive. validates_format_of :expiration_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :activation_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :some_other_date, :with =>

I''m a total Rails newbie and i''ve been struggling for hours today with one (prolly very silly) problem: I have a table portfolios that has many images: class Portfolio < ActiveRecord::Base has_many :images end class Image < ActiveRecord::Base belongs_to :portfolios end In the controller i define a list of active portfolios: @active_portfolios =

Hello all After being told of a funky date validator I will ask again for another validator :) Does anyone know of a plugin that validates that a field is the correct syntax for an IP Address? Thanks Jeff -- Posted via http://www.ruby-forum.com/.

I''ve noticed that validates_format_of will return invalid if the field is nil. Question 1) How should we declare a validation that will validate it with a regex if it is set, but, if the field is not set, just move on Question 2) Why is it done this way? The other validators are only invoked if the field is set . If you want to declare the field mandatory, you add a

hi, in my quest to grok ogg i tried to write a small program which extracts ogg_packets, and stuffs them back into ogg pages (which are then written to a file). extracting the packets works fine, but i have problems stuffing them into a new ogg stream. pseudo code: ogg_stream_init(os, serialno) foreach p in packets: ogg_stream_packetin(os, p) // try to extract a page

Hi all, I''ve got a form which accepts a "price" field and I''m attempting to validate it and allow some flexibility in the way the user enters it. It''s a numeric field but I want the user to be able to enter dollar signs and commas naturally in the data entry. I''m trying to understand how to use validates_format_of, and I''m not sure what

I''m using validates_format_of and the validation I want to do works, but I can''t get an error message to be displayed if the data is invalid: validates_format_of :mobile, :with => /\A[\+0-9]+\Z/, :message => " - Wrong" I have another validation some where else that does display the error message: " - Name is too long" validates_length_of :name,
