I’ve been chuggin along with Agile Web D. with Rails, got up to
Chapter 13 then discivered the Second Edition of the book.
I installed the latest Edge Rails (to get support for :decimal) so I
could get a feel for the migrations described in Interatiosn A1 and A2.
I’m working with a brand new rails app and database.
Below are the migration files and the trace from rake. Any ideas whats
up? Should I use a different version of Rails, or just roll back to the
last stable release and not use :integer instead of :decimal just so I
can get through the lesson?
#001_create_products.rb
class CreateProducts < ActiveRecord::Migration
def self.up
create_table :products do |t|
t.column :title, :string
t.column :description, :text
t.column :image_url, :string
end
end
def self.down
drop_table :products
end
end
#002_add_price.rb
class AddPrice < ActiveRecord::Migration
def self.up
add_column :products, :price, :decimal, :precision => 8, :scale =>
2, :default => 0
end
def self.down
remove_column :products, :price
end
end
