Datamapper DataMapper → 0.10.0

This may or may not be related to #931, and so may or may not be fixed already. Unfortunately I've had trouble upgrading to 0.10RC2 because of software not recompiling through MacPorts on Snow Leopard.

This one is really easily demonstrated with a spec example:

require 'rubygems'
 
require 'dm-core'
require 'spec'
require 'spec/autorun'
 
SQLITE_FILE = File.join(`pwd`.chomp, "test.db")
 
DataMapper.setup(:default, "sqlite3:#{SQLITE_FILE}")
DataMapper.setup(:reloaded, "sqlite3:#{SQLITE_FILE}")

class Parent
  include DataMapper::Resource
  property :id, Serial
  has n, :debts
end
  
class Debt
  include DataMapper::Resource
  property :id, Serial
  belongs_to :parent
end
 

Spec::Runner.configure do |config|
  config.before(:each) do
    Parent.auto_migrate!
    Debt.auto_migrate!
  end
  
  config.before(:each) do    
    DataMapper::Repository.context << repository(:default)
  end
  
  config.after(:each) do
    DataMapper::Repository.context.pop
  end
end
 
describe Parent, "with debts, 1 to n" do
  before(:each) do
    @parent = Parent.new
    @parent.debts << Debt.new(:parent => @parent)
    @parent.save    
  end
  
  it "1 to n associations appears to be sharing associations across an identity map" do
    repository(:reloaded) do
      parent_reloaded = Parent.get(@parent.id)
      first_debt = parent_reloaded.debts.first
      Debt.get(first_debt.id).repository.name.should == first_debt.repository.name
    end
  end
end
