Use timestamp values to represent boolean data such as deleted, published, or subscribed.

An ActiveRecord extension providing convenience methods for timestamp management.

Convert datetime to boolean in ActiveRecord.

True/False fields have a great simplicity about them, and many times they're perfect for the job! But, it's not uncommon end up in a place where you'd really love to keep some degree of simplicity with a little more detail about when the value was changed. Sometimes you'll want to display that information to the user and other times you'll keep it for auditing or debugging purposes. Either way, boolean_timestamp makes the job easy from the beginning and adds very little code to your app.

ActiveRecord plugin for creating a boolean virtual attribute from a datetime column.
