wrong mix
we don't want people to be able to find by id ... that's the point of half this feature

perhaps consider writing a method : 

```ruby
def load_and_authorize_resource_by_key( options = {} )
   model_klass_name = self.class.controller_name.classify
   
   instance_variable_set( '@'+model_klass_name, 
   model_klass_name.constantize.find_by_key( params[:id] )

end

tu meke?


end

```
