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
typecast_value_ipaddr(value) click to toggle source

Typecast the given value to an IPAddr object.

# File lib/sequel/extensions/pg_inet.rb, line 89
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
