Rails 2.0.2 with few changes
Written by matt on December 17th, 2007
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 yourappname" 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:
1 2 3 4 5 6 7 |
ActionController::Base.asset_host = Proc.new { |source| if source.starts_with?('/images') "http://images.example.com" else "http://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.cachetemplateloading 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]

Hey! How come you didn't mention my world-changing bugfix?
- Fix that validatesacceptanceof still works for non-existent tables (useful for bootstrapping new databases). Closes #10474 [hasmanyjosh]
Anyone with an observer who tries to use the new db:migrate:reset task is going to be grateful for that one.
I think you just grabbed the CHANGELOG from the railties library, but there have been notable changes in ActiveRecord, ActiveResource, and ActionPack as well.
-
@josh, you're right, I only posted the CHANGELOG from railties. Article updated, sorry about that.
-
Is this an actual release? This come out of the blue....
-
P.S.
What changeset does this tag map to?
Actually, what's the best way sync if I have rails checked out to my app by way of rake rals:freeze:edge?
-
@alex, we are talking about Rails 2.0.2 stable. Just do sudo gem update rails. Then freeze rails (not Edge).
FYI, I covered the 2.0.2 tag, revision 8430
-
tasks: db:migrate:redo is really useful!
Thanks a lot for this one, I was missing it.
-
db:migrate:reset -- very useful! thx!
-
Your rake tasks got mentioned on the latest Rails Envy podcast ;)
