An obvious hint today: Don't keep production database passwords versioned in your database.yml config.
Remember to use filter_parameter_logging in your application controller to keep sensitive info out of your logs. http://bit.ly/56Yidq
Use formtastic for more readable forms: http://github.com/justinfrench/formtastic
When testing consider using factories instead of fixtures. They are easier to maintain and make testing a breeze. http://bit.ly/KwnTW
Make date & time formatting DRY by adding your own formats to core conversions so you can do: time.to_s(:my_format). http://bit.ly/75gWS2
http://github.com/aaronchi/jrails/ -- Replace Prototype with jQuery in your Rails projects and still have access to all of the js helpers.
Another way to change model attribute names in error messages is to use the built in i18n(http://bit.ly/4MA76k). Thanks @joshkalderimis
If you use subdomains in your app for accounts create a cucumber step like this for your tests: http://gist.github.com/249107
You can change the names of your model's attributes when showing error messages to your users by doing this: http://gist.github.com/248335
Memoize a method to cache computed results if that method will be used multiple times during one request. http://gist.github.com/247370
save_and_open_page can help you find problems with your cucumber steps. I like to wrap it in a step def: http://gist.github.com/246501
If you are like me you probably spend a lot of time in your Rails console. Make sure you use ~/.irbrc. Small ex: http://is.gd/57wFw
Clarification for the last point: *Rarely do I ever want to pull collections without a specific order.
Give your models default ordering by using default_scope :order => "column". Rarely do I ever want to pull collections ordered by id.
Keep production logs from all of your servers in one place with MongoDB. http://github.com/peburrows/mongo_db_logger
Use hirb (http://github.com/cldwalker/hirb/) to format your irb/console output. Make sure you use your .irbrc to initialize hirb.
http://yfrog.com/4fjj2p Try organizing your cucumber features into user roles. I like to use admin_user, anonymous and default_user.
Try to create named_scopes instead of model methods whenever possible. You will thank yourself later, I promise. Doc: http://bit.ly/5kEVNT
