Hmm. Let's DRY that up a little, eh?

class ApplicationController
  protected
  def new_from_params(obj)
    obj = obj.to_s
    klass = obj.camelize.constantize
    instance_variable_set("@#{obj}", klass.new(params[obj]))
  end
end


And then in your controller, call: 
new_from_params :property
which would automatically set 
@property
with the newly created object from params.

Perhaps that's a little *too* magic though. :-)
