Using two Ruby classes with same name

Question

I'm using JRuby and working with dates. The framework I'm in forces me to use both JodaTime's DateTime and Ruby's standard DateTime.

How do I handle them having the same name?

How do I refer to one when the other is also required?

Answer 1

You have to keep classes with the same name in different namespaces.

To avoid conflicts with Joda-Time's DateTime , you could assign the Java package to a constant:

require 'date'
require 'java'

JT = org.joda.time

JT::DateTime  # <- Joda-Time's DateTime
DateTime      # <- Ruby's DateTime
