overlaps?(other)

Compare two ranges and see if they overlap each other

(1..5).overlaps?(4..6) # => true
(1..5).overlaps?(7..9) # => false
# File activesupport/lib/active_support/core_ext/range/overlaps.rb, line 5
def overlaps?(other)
  cover?(other.first) || other.cover?(first)

to_default_s(format = :default)
Alias for: to_s
to_formatted_s(format = :default)

Convert range to a formatted string. See RANGE_FORMATS for predefined formats.

This method is aliased to to_s.

range = (1..100)           # => 1..100

range.to_formatted_s       # => "1..100"
range.to_s                 # => "1..100"

range.to_formatted_s(:db)  # => "BETWEEN '1' AND '100'"
range.to_s(:db)            # => "BETWEEN '1' AND '100'"

Adding your own range formats to #to_formatted_s

You can add your own formats to the Range::RANGE_FORMATS hash. Use the format name as the hash key and a Proc instance.

# config/initializers/range_formats.rb
Range::RANGE_FORMATS[:short] = ->(start, stop) { "Between #{start.to_s(:db)} and #{stop.to_s(:db)}" }
Also aliased as: to_s
# File activesupport/lib/active_support/core_ext/range/conversions.rb, line 24
def to_formatted_s(format = :default)
  if formatter = RANGE_FORMATS[format]
    formatter.call(first, last)
  else
    to_default_s
  end
