  - by 99miles

  I created a form with scaffold that includes two datetime fields. I replaced them with a datepicker, and now I'm trying to grab the date from within the controller. Instead of having ruby do all the magic work with the datefields, I instead just have to fields, start_date and stop_date that I want to use, but I can't figure out how to grab them from within my controller. Hints? Thanks!

• Are there any solutions for translating measurement units on Rails?

  I'd like to implement measurement unit preferences in a Ruby on Rails app. For instance, the user should be able to select between displaying distances in miles or in kilometers. And, obviously, not only displaying, but entering values, too. I suppose all values should be stored in one global measurement system to simplify calculations. Are there any drop-in solutions for this? Or should I maybe write my own?
