##
# Retrieves all primary values and an optional column and returns the
# results as an array of hashes in which the keys of these hashes are the
# IDs and the values the values of the specified column. This array can be
# used when creating <select> elements using the BlueForm helper.
#
# @example
# Sections::Model::Section.pk_hash(:name) # => {1 => 'Blog', 2 => 'General'}
#
# @param [Symbol] column The name of the optional column to select.
# @return [Hash]
#

self.select(:id, column.to_sym).each do |row|
hash[row.id] = row.send(column)
