mangle ActiveRecord
Dear Gurus on Rails! How do I change the behaviour of one method in ActiveRecord::ConnectionAdapters::SchemaStatements ?

It would not be DRY to repeat

MySQL connection problems on Dreamhost
To all fellow Dreamhosters out there... Sometimes my app mysteriously loses its connection to the database, resulting in a big ugly "Application Error (Rails)" page.

Rails without a db - how to run tests
I''m writing a simple app that doesn''t need to use a database. I added :active_record to the config.frameworks -= line in environment.rb file. This lets me run ./script/generate fine without complaining about no connection. However if I try to run a functional test, it complains about no connection being established. Well...I don''t want a connection to be established.

Nested hash from form params into create()?
Hi, I''m really excited about getting the create() method working on a nested hash. The Rails book make it seem like I''m close to doing the right thing but I think something very small is not quite right. The error at the below isn''t giving any hints that I understand. I have a form that produces a nested params hash and sends it to my add_to_cart controller method.
