  • State changed from “new” to “resolved”
  • Milestone set to “0.10.0”

  I just ran your pastie against the current next branch and get the expected behavior. Marking this as resolved.

  require 'rubygems'
  require 'dm-core'
  require 'dm-validations'
  
  class Element
    include DataMapper::Resource
  
    property :id, Serial
    property :type, Discriminator
    property :val, Integer
  end
  
  class LazyTextbox < Element
    property :content, Text, :lazy => false
    validates_present :content
  end
  
  class ActiveTextbox < Element
    property :content, Text
    validates_present :content
  end
  
  class LazyUnvalidatedTextbox < Element
    property :content, Text, :lazy => false
  end
  
  DataMapper.setup(:default, "sqlite3:///#{Dir.pwd}/content.db")
  
  DataMapper.auto_upgrade!
  
  lazy = LazyTextbox.create({:val => 10, :content => 'hello'})
  active = ActiveTextbox.create({:val => 10, :content => 'hello'})
  unvalid = LazyUnvalidatedTextbox.create({:val => 10, :content => 'hello'})
  
  
  # Doesn't work!
  e = Element.get lazy.id
  e.val = 20
  puts e.save
  puts e.val
  
  # Works when accessing the child class
  e = LazyTextbox.get lazy.id
  e.val = 20
  puts e.save
  puts e.val
  
  # Works when not lazy loaded
  e = Element.get active.id
  e.val = 20
  puts e.save
  puts e.val
  
  # Works when not validated
  e = Element.get unvalid.id
  e.val = 20
  puts e.save
  puts e.val

  Would love to test this out - is there an easy way to install 0.10 ? Can you point me towards any instructions?

  @David: Unfortunately it's not super easy, but it's not too hard, it'll probably take a few minutes to pull everything down and install it.

  The easiest way is to git clone extlib, do, dm-core and dm-more from the http://github.com/datamapper/ account. Then checkout the next branch, and run sudo rake install to install the edge gems. Make sure you install them in this order since each package is dependent on the one before it.
