Google Product Search Xml Generator
I have been working on a google base product search xml feed generator. It is in the form of a semi-customizable rake task. I have released this as a kind of rails plugin.
rake googlebase:generate generates an xml file of your products.
To configure, add Rails.root/config/google_base.yml
Example google_base.yml file in files/google_base.yml
As the structure of the xml is dependant on your product models I have left it to the programmer to modify the google.rake file and set the correct instance methods for returning product information, along with the named_scope for returning live products.
Instead of editing this rake file manually it would be good to add a plugin type class method which can take the configuration of your products and generate this automatically.
Its is available on github
