ActsAsAmazonProduct
This “acts_as” module makes it extremely simple to add Amazon integration to an existing model.
Setup
This code does not require changing any current database tables. It only requires adding one migration for a single new table used to cache responses from Amazon:
ActiveRecord::Base.connection.create_table :amazon_products do |t| t.column :asin, :string t.column :xml, :text t.column :created_at, :datetime, :null => false t.column :amazonable_id, :integer, :default => 0, :null => false t.column :amazonable_type, :string, :limit => 15, :default => “”, :null => false end
Using acts_as_amazon_product
Add the “acts_as” line to your model. Only :access_key is required. The :asin and :name assignments override what attributes in your class should be used for a direct lookup (item_looup) or general search (item_search). If no value is assigned to :asin then a general search is made and the first item (sorted by salesrank) is assigned (this functionality will likely change).
require ‘acts_as_amazon_product’
class Book < ActiveRecord::Base acts_as_amazon_product :asin => ‘isbn’, :name => ‘title’, :access_key => ‘0123456’, :associate_tag => ‘assoc-20’ end
You can now access the Amazon data in your views like so (see):
@book = Book.new(:title => ‘Getting Things Done’) @book.amazon.isbn @book.amazon.title @book.amazon.author @book.amazon.small_image_url or @book.amazon.get(‘itemattributes/foobar’)
Unit tests
There are tests you can run in the [gem]/test directory. Just create a test/config.yml from the example and run “Rake test” from the [gem] directory.
