I''m not really creating a rails app, but may integrate this with rails
down the road.
I''ve adapted rss2mysql.rb from:
Practical Ruby Gems
http://www.apress.com/book/view/9781590598115
Chapter 10, parsing feeds
but am tweaking everything. Currently I have a rakefile, but am a bit
unclear about what sort of tasks go in there. For instance, grabbing rss
data from the interwebs could be a task, so maybe it should go in the
rake file?
Also, the rake file should have provisions to add/drop tables?
I started to put some of the db interactions into the rakefile, and then
thought that maybe everything in this file (script?) belongs in a
rakefile. Where do you draw the line?

thufir@ARRAKIS:~/rb$ cat rss2mysql.rb
require ''rubygems''
require ''active_record''
require ''feed_tools''
require ''yaml''
db = YAML.load_file("database.yml")
ActiveRecord::Base.establish_connection(
:adapter => db["adapter"],
:host => db["host"],
:username => db["username"],
:password => db["password"],
:database => db["database"])
class Item < ActiveRecord::Base
end
unless Item.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
t.column :html, :string
end
end
end
puts "connected"
#feed =
FeedTools::Feed.open(''http://www.slashdot.org/index.rss'')
feed =
FeedTools::Feed.open(''www.amazon.com/rss/tag/blu-ray/new'')
feed.items.each do |feed_item|
if not (Item.find_by_title(feed_item.title) \
or Item.find_by_url(feed_item.link) \
or Item.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
end

Also, what sort of IDE is popular for ruby? Eclipse?
thanks,
