I have three tables:
class Name
include DataMapper::Resource
property :id, Serial
property :normalized_name, String, :unique_index =>
true, :required => true
property :name, String, :required => true
property :link_status, Enum, :flags =>
[:new, :linked], :default => :new
has n, :people_names
has n, :people, :through => :people_names
def name=(value)
attribute_set(:name, value.upcase)
attribute_set(:normalized_name, Name.normalize(value))
end
def Name.normalize(orig_name)
n = orig_name.upcase
n.gsub!(',', '')
n.gsub!('.', '')
n.gsub!(' ', '')
n
end
end
class Person
include DataMapper::Resource
property :id, Serial
property :name, String
has n, :people_names
has n, :names, :through => :people_names
end
class PeopleName
include DataMapper::Resource
property :id, Serial
property :link_type, Enum, :flags =>
[:validated, :unvalidated], :default => :unvalidated
belongs_to :person
belongs_to :name
end
I create a Person object as p and a Name object as n, when I assign
p.names << name and n.person << person I can then do p.names and I get
the name assigned, same with n.person I get the right person. But how
do I access the :link_type property from the PeopleName table. If I
do a PeopleName.all I get an empty array.
How do I access the additional information in the join table?
