Time in Text Field
Although Rails does allow you to edit time attributes with text fields, it's not very flexible. In this episode you will learn how to use a virtual attribute to format the time to your liking.

Your site may be at risk! When using mass assignment, you are giving the user complete control over that model and its associations. See how a hacker might use this vulnerability and learn how to stop it in this episode.
