  • State changed from “new” to “confirmed”

  I can confirm this on latest next branch. I put together a standalone based on the above snippet and added a few comments on what seems to happen.

  require 'rubygems'
  require 'dm-core'
  
  DataMapper::Logger.new(STDOUT, :debug)
  DataMapper.setup(:default, 'sqlite3:memory:')
  
  class Apple
    include DataMapper::Resource
    property :id,         Serial
    has n, :oranges, :through=>Resource  
  end
  
  class Orange
    include DataMapper::Resource
    property :id, Serial
    has n, :apples, :through=>Resource
  end
  
  DataMapper.auto_migrate!
  
  Apple.create;  Apple.create;  Apple.create
  Orange.create; Orange.create; Orange.create
  
  a = Apple.get(1)
  o = Orange.get(1)
  a.oranges << o
  a.save
  a = Apple.get(2)
  o = Orange.get(2)
  a.oranges << o 
  a.save
  
  a = Apple.get(3)
  
  o = Orange.get(1) # orange_1 is already in apple_1.oranges (doesn't end up in output - FAIL)
  a.oranges<<o
  a.save
  o = Orange.get(2) # orange_2 is already in apple_2.oranges (doesn't end up in output - FAIL)
  a.oranges << o
  a.save
  o = Orange.get(3) # orange_3 isn't part of any oranges collection yet (ends up in output - PASS)
  a.oranges << o
  a.save
  
  Apple.all.each do |a|
    puts "apple_id = #{a.id}"
    a.oranges.each do |o|
      p "apple_#{a.id}.oranges = #{o.id}"
    end
  end
  
  # apple_id = 1
  # "apple_1.oranges = 1"
  # apple_id = 2
  # "apple_2.oranges = 2"
  # apple_id = 3
  # "apple_3.oranges = 3"

  • Milestone changed from “0.10.0” to “0.10.1”

  It is unlikely this will be ready for the 0.10.0 release. Bumping to 0.10.1 milestone
