default_scope in rails 3 with lambda

Hello,

i am trying to set a default scope so I can pass a proc as argument. This is the code:

default_scope lambda { where(“language = ?”, I18n.locale.to_s) }

When I try to get the values, the following error is raised:

NoMethodError: undefined method includes_values' for #<Proc:0xb6d85b9c> from /home/daniel/.rvm/gems/ruby-1.8.7-p299/gems/activerecord-3.0.0.beta4/lib/active_record/relation/spawn_methods.rb:10:in send’
