Validate DateTime object in Ruby

Question

A constructor in following code receives a DateTime object in the parameter

class Test
    attr_accessor :dateTime

    # Takes DateTime object as input
    def initialize(dateTime)
        @dateTime = dateTime
    end
end

How can I validate if dateTime parameter passed to the constructor is valid DateTime object or not?

One way to find out is by using:

if dateTime.class == DateTime

But is there a better way to do it?

Remember, dateTime is DateTime object and not a string

Answer 1

You can check it by dateTime.is_a?(DateTime) it will return boolean
