Module: Ldapter::BeforeTypeCast

Defined in:
lib/ldapter/before_type_cast.rb

Overview

Mixing in this module into an entry class causes special _before_type_cast accessors to appear on instances. Said accessors always return a string, joining multiple elements with newlines. This may prove useful in conjunction with Rails.

class L < Ldapter::Class(:adapter => :ldap_conn)

class Top
  include Ldapter::BeforeTypeCast
end

end

def respond_to?(method)
  if method.to_s =~ /(.*)_before_type_cast$/
    (may + must).include?($1.tr('-_','_-')) || super
  else
    super
  end
end

- (Object) write_attribute(attribute, value)

If the attribute is human readable and allows multiple values, and a string value is given for assignment, split said string upon newlines. This reverses the effect of #read_attribute_before_type_cast.
