Hi.
In the Amazon/Ruby module. when someone searches for an item, and it''s
not found on amazon''s side, there''s a nasty error page that is
displayed. I''d simply like to test if there are no results, to redirect
to a controller/action inside my rails app.
In the search.rb amazon file, in the RDoc, it says that if a block is
available, it will throw it all into @products, but if not it seems to
go here within the search.rb file:
class SearchError < StandardError; end
or would it help if i put the ruby/amazon module inside my rails app?
Thank you very much.
PS: the error:
Amazon::Search::Request::SearchError (Invalid Asin : 0234526345):

There''s more about exceptions at: http://www.rubycentral.com/book/tut_exceptions.html What you want to do is to put your request to amazon/ruby inside a begin/rescue block. eg. begin result = req.asin_search(asin_value.to_s) create_instance_from_amazon(result.products[0]) rescue # Handle the error, redirect, or whatever end # Handle the result, continue execution James. -- James Stewart : Freelance Web Developer Work : http://jystewart.net/process/ Play : http://james.anthropiccollective.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thank you Mr James. Now for the re-directing. I guess I should put the amazon/ruby files in my rails app''s public html to get it to re-drect properly to one of my controller/actions now.

For example: require ''amazon/search.rb'' class MyController < ApplicationController include Amazon::Search def amazon_search req = Request.new(dev_key, associates_id) result = req.asin_search(asin_value.to_s) # do something with your result rescue redirect_to :action => ''error_page'' end def error_page end end You might want to take a look at my loads_from_amazon plugin: http://jystewart.net/process/archives/2006/07/loads_from_amazon-ruby- on-rails-plugin/ James. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
