I would like to specify a named scope in a Module, to keep DRY. Example:

class Article \< \< ActiveRecord::Base

include ReferenceData

# …

end

module ReferenceData

def self.included(base)  
base.extend(ClassMethods)  
end

module ClassMethods

```
named_scope :released, :conditions => {:is_released => true}

```

end

end

This does not work:

> > Article.released  
> > NoMethodError: undefined method `named\_scope’ for  
> > ReferenceData::ClassMethods:Module

Do you know how to specify my named scope inside a mixin module?  
Thanks a lot,
