Rails 2 0 2 With Few Changes

What’s new?

Rails default database is now sqlite3. If you are running Leopard, everything is already setup for you. As DHH mentioned, just “rails -d mysql your_app_name” if you want to generate a new app preconfigured for MySQL. Sqlite3 is great and if the only reason why you didn’t give it a try is because you have to use CocoaMySQL, then check out sqlitebrowser
Other new feature: rake secret to generate a key used to encrypt your session. Really useful task when you’re migrating an app to 2.x
To improve performance, some changes were made to the template caching and you have to restart your production server after a template modification.
Validates acceptance of still works for non-existent tables . (sorry Josh, I won’t post after 2am, especially when I forget your life changing bug fix ;) )
Added option to pass proc to ActionController::Base.asset_host for maximum configurability. Example:

1234567
```
ActionController::Base.asset_host = Proc.new { |source|<tt>
```
if source.starts_with?('/images') "https://images.example.com" else "https://assets.example.com" end }
Finally, I added 2 new rake tasks: db:migrate:redo and db:migrate:reset

db:migrate:redo rolls back your database and then migrates it up. You can define the STEP constant to specify the amount of steps you want to rollback. This task is very useful in development mode when making a modification to the latest migration(s). db:migrate:reset will drop your database, re create it and migrate it up. Only use this task if you really have to and only in development/test environment. Use db:reset in production mode since it uses the schema.rb file and won’t go through the hundreds of migrations you might have.

Changeset

2.0.2 (December 16th, 2007)

Changed the default database from mysql to sqlite3, so now running “rails myapp” will have a config/database.yml that’s setup for SQLite3 (which in OS X Leopard is installed by default, so is the gem, so everything Just Works with no database configuration at all). To get a Rails application preconfigured for MySQL, just run “rails -d mysql myapp” [DHH]
Turned on ActionView::Base.cache_template_loading by default in config/environments/production.rb to prevent file system stat calls for every template loading to see if it changed (this means that you have to restart the application to see template changes in production mode) [DHH]
