module Sequel::Postgres::InetDatabaseMethods
Methods enabling Database object integration with the inet/cidr types.
Public Class Methods
extended(db)
click to toggle source
Reset the conversion procs when extending the Database object, so it will pick up the inet/cidr converter. Also, extend the datasets with support for literalizing the IPAddr types.
# File lib/sequel/extensions/pg_inet.rb, line 40 def self.extended(db) db.instance_exec do extend_datasets(InetDatasetMethods) meth = IPAddr.method(:new) add_conversion_proc(869, meth) add_conversion_proc(650, meth) if respond_to?(:register_array_type) register_array_type('inet', :oid=>1041, :scalar_oid=>869) register_array_type('cidr', :oid=>651, :scalar_oid=>650) register_array_type('macaddr', :oid=>1040, :scalar_oid=>829) end @schema_type_classes[:ipaddr] = IPAddr end end
Public Instance Methods
bound_variable_arg(arg, conn)
click to toggle source
Convert an IPAddr arg to a string. Probably not necessary, but done for safety.
Calls superclass method
# File lib/sequel/extensions/pg_inet.rb, line 57 def bound_variable_arg(arg, conn) case arg when IPAddr "#{arg.to_s}/#{arg.instance_variable_get(:@mask_addr).to_s(2).count('1')}" else super end end
Private Instance Methods
bound_variable_array(a)
click to toggle source
Handle inet[]/cidr types in bound variables.
Calls superclass method
# File lib/sequel/extensions/pg_inet.rb, line 69 def bound_variable_array(a) case a when IPAddr "\"#{a.to_s}/#{a.instance_variable_get(:@mask_addr).to_s(2).count('1')}\"" else super end end
schema_column_type(db_type)
click to toggle source
Make the column type detection recognize the inet and cidr types.
Calls superclass method
# File lib/sequel/extensions/pg_inet.rb, line 79 def schema_column_type(db_type) case db_type when 'inet', 'cidr' :ipaddr else super end end
schema_post_process(_)
click to toggle source
Set the :ruby_default value if the default value is recognized as an ip address.
Calls superclass method
# File lib/sequel/extensions/pg_inet.rb, line 89 def schema_post_process(_) super.each do |a| h = a[1] if h[:type] == :ipaddr && h[:default] =~ /\A'([:a-fA-F0-9\.\/]+)'::(?:inet|cidr)\z/ h[:ruby_default] = IPAddr.new($1) end end end
typecast_value_ipaddr(value)
click to toggle source
Typecast the given value to an IPAddr object.
# File lib/sequel/extensions/pg_inet.rb, line 99 def typecast_value_ipaddr(value) case value when IPAddr value when String IPAddr.new(value) else raise Sequel::InvalidValue, "invalid value for inet/cidr: #{value.inspect}" end end
