Hi, I'm trying to figure out why I can't dump and load a ActiveRecord object with YAML.
Please see the gist below for how to replicate, and the exact error I'm getting. https://gist.github.com/84f44da695b218ae9474 Basically I create a new project, new database, and new model. Create an instance of the model, call to_yaml on it, store that, and then try and load an object from that. This general idea, of reconstituting a model from it's YAML representation works in some of my projects, but not in any new ones. I have no idea why this would be the case. Changing the type of the yaml dump from !ruby/object:Dummy to !ruby/ActiveRecord:Dummy helps a little bit, but still returns something weird. ruby-1.9.2-p0 > tom => "--- !ruby/object:Dummy \nattributes: \n id: 1\n name: Tim\n created_at: 2011-01-27 21:12:33.327345\n updated_at: 2011-01-27 21:12:33.327345\nattributes_cache: {}\n\nchanged_attributes: {}\n \ndestroyed: false\nmarked_for_destruction: false\npersisted: true \npreviously_changed: {}\n\nreadonly: false\n" ruby-1.9.2-p0 > bill = tom.gsub("object", 'ActiveRecord') => "--- !ruby/ActiveRecord:Dummy \nattributes: \n id: 1\n name: Tim \n created_at: 2011-01-27 21:12:33.327345\n updated_at: 2011-01-27 21:12:33.327345\nattributes_cache: {}\n\nchanged_attributes: {}\n \ndestroyed: false\nmarked_for_destruction: false\npersisted: true \npreviously_changed: {}\n\nreadonly: false\n" ruby-1.9.2-p0 > YAML.load(bill) => #<Syck::DomainType:0x00000100c634b8 @domain="ruby.yaml.org,2002", @type_id="ActiveRecord:Dummy", @value={"attributes"=>{"id"=>1, "name"=>"Tim", "created_at"=>"2011-01-27 21:12:33.327345", "updated_at"=>"2011-01-27 21:12:33.327345"}, "attributes_cache"=>{}, "changed_attributes"=>{}, "destroyed"=>false, "marked_for_destruction"=>false, "persisted"=>true, "previously_changed"=>{}, "readonly"=>false}> -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
