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

This is kind of frustrating (but no doubt helpful in the long run) that after following along and coding , and d/l the code the same error is appearing. For those who are familiar with the depot app, I''ve run into a problem after fixing the cart to reflect quanitites. I worked through the intended error messages but now have this appearing: SyntaxError in StoreController#add_to_cart

I really hope this is not a bad question (as in he''s abusing the list). However I could use a little direction (even though I''m reading books, tutorials) Right now I''m getting a undefined method `category'' for 4:Fixnum The specific lines from the rhtml file are: <td><%= link_to position.category_id.category, :action => "show", :id =>

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! You

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

Reviews Wanted. I''ve read the tables of contents and haven''t yet made up my mind. Is one book clearly better than the other? Is one clearly full of bugs? Is one so much further ahead that there is no choice? Are they both so incomplete that I should just wait and only cook real food? Do trains still have dining cars?

Hi, I am receiving an LLVM Error from a custom 16-bit backend I am creating. I am having trouble understanding the error/problem and how to go about solving it. The error is: LLVM ERROR: Cannot select: t29: i32,ch = load<LD2[%x.addr], anyext from i16> t14, FrameIndex:i16<0>, undef:i16 t7: i16 = FrameIndex<0> t9: i16 = undef In function: mul_add Can anyone provide any

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

Apologies first, because I need to ramp up on Ruby and coding Ruby in Rails, however it''s my 3rd day with this beast :) so I''m asking : When I added protected methods to the model before it was like: protected method.................... end Would this be a valid way to write a protected method as well ?: attr_protected :column1, :column2 Perhaps this particular call

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

This maybe a silly question and the fact that I need a sanity check might even be weirder, but I''m trying to set realistic expectations for myself. I''ve been reading reading reading AWDWR, Ruby on Rails, some of the PickAxe, and even done a few recipes from Rails Recipes. This is all of two weeks. I feel that I''ve learned a considerable amount but going through the

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

Appreciate any help - I am working through Agile web development (4.0) and am stuck on the deployment using phusion passenger. I get this: "Forbidden You don''t have permission to access / on this server." when I put depot.yourhost.com in the browser. I have been through various web searches and for file permissions and suggestions to change the <Files> container.

Sorry to be such a pest but I am trying to learn Ruby, Rails and RSpec all at one go and it is a bit overwhelming. I have previously completed the depot tutorial in the Agile Web Dev with rails book and now I am trying do do it again using RSpec. What I would like to know now is why I am getting a rake failure error at the end of every spec:models run. Is this the expected behaviour when a test

I''m following the example Depot app in Agile Web Development with Rails. The scaffold fails because it is not using the correct host for the user. Here is the error that the scaffold emits: Access denied for user ''jimmy''@''%'' to database ''depot_development'' The MySql user ''jimmy'' was created with the host of

Hi All So I am a first-time caller ;-) ... and have been trying to apply RSpec to the depot example in Dave Thomas'' book as I build the application. I am having a problem testing the admin controller create method and cannot quite see where I am going wrong so was hoping for a pointer :-) My spec looks like: describe AdminController do before(:each) do @product =

Fixed the network issue by removing the net udev rule, somehow that was causing the network no to come up.

Hi. I''ve just started using Ruby on Rails. Now I''ve got my first problem. I generated a new migration ''add_price'' and get the message:

Hi: I''m running RoR 1.1 I''m going through the Agile book Depot example and I want to generate my next migration file so i''m typing ./script/generate migration depot I was sort of expecting to get the file 002_depot.rb .. instead i''m being informed that there already exists a migration named depot..and no new file is generated.. should I be using a new

Yesterday, I was having a problem with db:migrate. I was told my version of rails was too old, and I needed to install it from gems instead of the version in my version of Ubuntu. Since then, I''ve done that, and I built ruby 1.8.4 from source and installed it. The installation was to /usr/local/bin. As my distribution had put ruby 1.8.3 in /usr/bin, I renamed that and put a link to
