similar to: New version of AWDwR

Heya everyone! I am quite new to Rails and I am reading AWDwR. I am at Task E "Check Out!". I understand it quite well, but I have a problem with the last playground exercise: Add a Table which contains the payment types. All goes well, but I am not sure whether I should use has_many or has_one(as in the Playground wiki at http://wiki.pragprog.com/cgi-bin/wiki.cgi/PT-E-3). I use the

I''m getting to the point now where I really need to start trapping the errors. So from my AWDWR book, I added the following directly from the book into application.rb... def rescue_action_in_public(exception) case exception when ActiveRecord::RecordNotFound, ActionController::UnknownAction render(:file => "#{RAILS_ROOT}/public/404.html",

Hi, I''m trying to follow the "AWDR" example of storing certain types of numbers (in my case, percentages not money) as integers in the database. I understand from the Depot application how to format the output to have 2 places (or n places for that matter) decimal. Now, I"m wondering about the input. It''s more natural for people to enter numbers as

In an early section on Action View, showing code being put directly into the rhtml file: <% require ''date'' DAY_NAMES = %w{ Sunday Monday Tuesday Wednesday Thursday Friday Saturday } today = Date.today %> <h1>Hello, Dave</h1> <p> It''s <%= DAY_NAMES[today.wday] %>. Tomorrow is <%= DAY_NAMES[(today + 1).wday %>. </p> I get this

So, I''ve been listing to stuff folks have been saying about the Bookman font we use. Most people like the font, but some feel there aren''t enough words/line, so your eyes move too much. So, I spent the weekend playing with typography, and I''ve come up with a compromise. The thing is: it looks good to me, but I don''t want to mess up the read for others

Hello all, I''m having great trouble accessing a constant declared in a helper for one of my view templates. I am trying to create a grouped selection list based on a predefined set of values. Rather than declare this set of values in the view, I wanted to put it in the helper that automatically gets included for the view. Unfortunately, it doesn''t seem to work. All methods

I''m having a problem with one of the migration files from the depot application. ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate == AddPrice: migrating ======================================================== -- add_column(:products, :price, :decimal, {:scale=>2, :default=>0, :precision=> 8}) rake aborted!

I''ve uploaded the B1.12 version of AWDwR. The major changes include: - Justin Gehtland''s new chapter on Web 2.0 - James Duncan Davisdon''s chapter on deployment (this is an interesting one---JDD has strong opinions on how a Rails application should be deployed, and the chapter mirrors this. You''ll find it short and easy to follow). - I changed the

Hi I am new to rails and I was trying to get version 2.1.1 installed so that I could run lovdbyless and play with Rails to see what it was like. When trying to install lovdbyless I kept getting problems when running "rake" so I looked around for an answer and did what the forums said, and then i''d get another error and i''d go through the same process. Now I am getting

ANNOUNCING AGILE WEB DEVELOPMENT WITH RAILS, SECOND EDITION =========================================================== http://www.pragmaticprogrammer.com/titles/rails2/ Rails has changed a lot since we announced the first edition of the book a year ago.

People, I''m looking at the migrate example on p 74 of the rails2.pdf It''s a simple example of using a migration to add a column to the products table. Here is a copy of the migration file named 002_add_price.rb after I generated and then edited it: class AddPrice < ActiveRecord::Migration def self.up add_column :products, :price, :decimal, :precision => 8, :scale

Now that Rails core converts a database''s decimal type into a Ruby BigDecimal type, is it ok to now store money information as a decimal in the database (instead of an integer)? Joe

Hey all, I''m following along with AWDWR, specifically the unit testing. On page 148, it shows you how Test::Unit::TestCase will automatically define instance variables based on your fixtures. It doesn''t seem to actually work, though. It seems that both @artists ["beatles"]["name"] and @beatles.name are nil objects in my test, where as

I copied (and modified) this code from AWDWR: def rescue_action_in_public(exception) case exception when ActiveRecord::RecordNotFound, ActionController::UnknownAction render :template=>''/error'', :layout=>''application'', :status=>''404 Not Found'' else render :template=>''/error'',

Hi I''m working on the AWDWR book and I''m on the admin section of the book. I have rails 2 installed on my machine and I have ran into an error when I created my controller login but when I go to http://localhost:3000/login/index I get this error: No route matches "/login/index" with {:method=>:get} I haven''t touched the routes.rb file and when I generated

Hi all, Rails 1.1.4 Rake 0.7.1 PostgreSQL 8.1.4 Windows XP Pro I checked for errata on pragmaticprogrammer.com, but didn''t see any explicit mention of this issue. I''m going over the depot example in AWDwR, 2nd ed, and I can''t get the migration to work on p. 82. Specifically, the AddTestData example (with reduced description text to save my fingers some typing):

Hello. Where is there an Agile Messageboard? On the first part of the Depot example, a price field shouldn''t be an integer right? (it should be more of a float since a price has decimals) Dominic Son -- Posted via http://www.ruby-forum.com/.

I''m having a particularly difficult time undersanding one lesson from this book. This is in relation ot how one would grab "search" parameters from web forms to search for records in the database. I understand the :conditions part of find() but am confused on the code: 1- name = params[:name] pos = Order.find(:all, :conditions => ["name = ? and pay_type =
