In Rails 2 you're able to run script/console --sandbox so you can play with production data and not accidentally break anything. I can't seem to find the equivalent command for Rails 3. Does anyone know what it is? Easy, type in: bundle exec rails c -s and that is it. $ bundle exec rails c --help Usage: console [environment] [options] -s, --sandbox Rollback database modifications on exit. --debugger Enable ruby-debugging for the console. --irb DEPRECATED: Invoke `/your/choice/of/ruby script/rails console` instead It is simple, but, sometimes, if you are not running rails executable using

I've got an initialization file config/initializers/linkedin.rb that sets up the Linkedin gem so that my app can connect to the LinkedIn service and run queries. I'm now testing out some new features and I want to use the console for this.

Any ideas on how to use the application initializers from within the console so that I don't have to run this by hand every time? Thanks! Try this: load "#{Rails.root}/config

I am trying out Node.js Express framework, and looking for plugin that allows me to interact with my models via console, similar to Rails console. Is there such a thing in NodeJS world? If not, how can I interact with my Node.js models and data, such as manually add/remove objects, test methods on data etc.?

I have this testingdatabase which, by now, is stuffed with junk. Now I've done a few Table.destroy_all commands in the rails console which deletes all records and dependencies which is awesome.
