Datamapper DataMapper

The following does not work:

Setting FKs as private is needed to protect them against mass assignment, but then association code does not work. See the following example.

#!/usr/bin/env ruby -KU
require "rubygems"
require "dm-core"

class User
  include DataMapper::Resource
  
  property :id,   Serial
  property :name, String
  
  has n, :comments
end

class Comment
  include DataMapper::Resource
  
  property :id,      Serial
  property :user_id, Integer, :accessor => :private
  property :body,    String
  
  belongs_to :user
end

DataMapper.setup(:default, "sqlite3::memory:")
DataMapper.auto_migrate!

user = User.create(:name => "Carl")
user.comments.create(:body => "Hello World")

comment = Comment.first
puts "#{comment.user.name} said: #{comment.body}"
