Helper method for parsing the output from date_select fields.

parse_date_select_values.rb

# Public: Parse values from Rails date_select form helper.
#
#   dsv - Stands for Date Select Values. Pass in whatever hash
#     contains the attributes of the date_select box.
#   name - Name of the Date Select. For example, if your params
#     contain 'date_of_birth(2i)' then your name would be
#     'date_of_birth' (which happens to be the default)
#
# Returns a Date object.
def parse_date_select_values(dsv, name='date_of_birth')
  Date.new dsv["#{name}(1i)"].to_i, dsv["#{name}(2i)"].to_i, dsv["#{name}(3i)"].to_i
