module Sequel
module Plugins
# The identifier_columns plugin makes Sequel automatically
# handle column names containing 2 or more consecutive
# underscores when creating or updating model objects.
# By default, this doesn't work correctly in Sequel, as it
# handles such symbols specially.
#
# This behavior isn't the default as it hurts performance,
# and is rarely necessary.
#
# Usage:
#
# # Make all model subclasses handle column names
# # with two or more underscores when saving
# Sequel::Model.plugin :identifier_columns
#
# # Make the Album class handle column names
# # with two or more underscores when saving
# Album.plugin :identifier_columns
module IdentifierColumns

def _insert_values

end
# Use identifiers for value hash keys when updating.
def _update_without_checking(columns)
super(identifier_hash(columns))
end
# Convert the given columns hash from symbol
# keys to Sequel::SQL::Identifier keys.
def identifier_hash(columns)
h = {}
columns.each{|k,v| h[Sequel.identifier(k)] = v}
