>From the docs:
===============
If the objects cannot be located as instance variables, you can add an extra
:object parameter which gives the actual object (or array of objects to
use):
error_messages_for 'user', :object => @question.user
===============
If using the :object key, it bypasses that line you mentioned altogether:
if object = options.delete(:object)
objects = [object].flatten
else
objects = params.collect {|object_name|
instance_variable_get("@#{object_name}") }.compact
end
Never tried it, but that should work :)
