  Here's how to reproduce this:

  
  require 'dm-core'
  require 'dm-constraints'
  
  class Book
    include DataMapper::Resource
    property :id, Serial
    belongs_to :author
    has n, :reviews
  end
  class Review
    include DataMapper::Resource
    property :id, Serial
    belongs_to :book
  end
  class Author
    include DataMapper::Resource
    property :id, Serial
    has n, :books
    has n, :review, :through => :books
  end
  

  This raises:

  There is no problem when i use 0.9.10 version.

  Environment: ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-freebsd8]

  What results do you get with the dm-core/next branch?

  • State changed from “accepted” to “resolved”

  I can confirm this is now resolved with the dm-core/next and dm-more/next branch.

  Attached is a script that demonstrates the fix.
