I’m thinking that the API for this gem has changed, hence the error?
I’m
looking into the documentation. Else, I’m not sure how to approach an
undefined method.
I pulled the code from:

This call creates a connection to our database.
ActiveRecord::Base.establish_connection(
:adapter => “mysql”,
:host => “127.0.0.1”,
:username => “ruby”, # Note that while this is the default setting for
MySQL,
:password => “password”, # a properly secured system will have a
different MySQL
# username and password, and if so, you’ll need to
# change these settings.
:database => “rss2mysql”)
class Items < ActiveRecord::Base
end
If the table doesn’t exist, we’ll create it.
unless Items.table_exists?
ActiveRecord::Schema.define do
create_table :items do |t|
t.column :title, :string
t.column :content, :string
t.column :source, :string
t.column :url, :string
t.column :timestamp, :timestamp
t.column :keyword_id, :integer
t.column :guid, :string
end
end
end
feed=FeedTools::Feed.open(feed_url)
feed.items.each do |feed_item|
if not (Items.find_by_title(feed_item.title)
or Items.find_by_url(feed_item.link)
or Items.find_by_guid(feed_item.guid))
puts “processing item ‘#{feed_item.title}’ - new”
Items.new do |newitem|
newitem.title=feed_item.title.gsub(/<[^>]*>/, '')
newitem.guid=feed_item.guid
if feed_item.publisher.name
newitem.source=feed_item.publisher.name
end
newitem.url=feed_item.link
newitem.content=feed_item.description
newitem.timestamp=feed_item.published
newitem.save
end
else
puts “processing item ‘#{feed_item.title}’ - old”
end
