require 'date'
module RandomData
# Defines methods for random date generation
module Dates
# Returns a date within a specified range of days. If dayrange is an Integer, then the date
# returned will be plus or minus half what you specify. The default is ten days, so by default
# you will get a date within plus or minus five days of today.
#
# If dayrange is a Range, then you will get a date the falls between that range
#
# Example:
#
# Random.date # => a Date +/- 5 days of today
# Random.date(20) # => a Date +/- 10 days of today
# Random.date(-60..-30) # => a Date between 60 days ago and 30 days ago
#
def date(dayrange=10)
if dayrange.is_a?(Range)
offset = rand(dayrange.max-dayrange.min) + dayrange.min
else
offset = rand(dayrange*2) - dayrange
end
Date.today + offset
end
# Returns a date within the specified Range. The Range can be Date or String objects.
#
#Example:
# min = Date.parse('1966-11-15')
# max = Date.parse('1990-01-01')
# Random.date(min..max) # => a Date between 11/15/1996 and 1/1/1990
# Random.date('1966-11-15'..'1990-01-01') # => a Date between 11/15/1996 and 1/1/1990
#
