Introduction to Active Record
We're going cover Active Record hands-on and from the top down: querying, associations, scopes, validations, joins, eager-loading, transactions, and more.
All the material we learn will work with any database supported by Active Record.
Before class, please view Active Record Queries in Rails 3 by RailsCasts.
I'll set up a hangout and post the link in the whiteboard at 7.
