I just tried upgrading to Rails 3.2.0.rc1 and found that it had an odd effect on one of my inherited documents. An exception is thrown if I try to access a field defined in the document subclass, although fields defined in the superclass are fine. I have reverted so this isn't a significant issue for me right now, but you might want to be aware of this.
class Region include Mongoid::Document field :population, type: Integer ... end class City < Region field :state_code, type: String ... end
> c = City.first => #<City _id: 4ecc093f1bead23de3000127, _type: "City", geo: [37.7507, -122.235], region_ids: [BSON::ObjectId('4ecc09381bead23de3000005'), BSON::ObjectId('4ecc093a1bead23de300003d'), BSON::ObjectId('4ecc093a1bead23de300003e')], bbox: nil, bounds: nil, name: "Alameda", key: "alameda", description: nil, sub_type: "city", mysql_id: 301696, parent_id: nil, population: 72259, default_address_id: BSON::ObjectId('4ecc0a321bead23de3008044'), state_code: "CA"> > c.state_code NoMethodError: undefined method `attribute' for #<City:0x00000104343a50> from /gems/activemodel-3.2.0.rc1/lib/active_model/attribute_methods.rb:407:in `method_missing' from /gems/mongoid-2.3.3/lib/mongoid/attributes.rb:184:in `method_missing' from /gems/activemodel-3.2.0.rc1/lib/active_model/attribute_methods.rb:345:in `state_code' from (irb):2 from /gems/railties-3.2.0.rc1/lib/rails/commands/console.rb:47:in `start' from /gems/railties-3.2.0.rc1/lib/rails/commands/console.rb:8:in `start' from /gems/railties-3.2.0.rc1/lib/rails/commands.rb:41:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main> > c.population => 72259
