Extracts options from a set of arguments. Removes and returns the last element in the array if it's a hash, otherwise returns a blank hash.
def options(*args) args.extract_options! end options(1, 2) # => {} options(1, 2, :a => :b) # => {:a=>:b}
# File lib/active_support/core_ext/array/extract_options.rb, line 14 def extract_options! last.is_a?(::Hash) ? pop : {} end
