Hi all,
I'm wondering what the best practices/conventions are for passing parameters to models I am writing. Is it better to pass ActiveRecord objects, or their database IDs?
I personally would pass activerecord objects. Sometimes you might waste a little if you do just use that object for it's id but I wouldn't worry about that too much. Apart from anything else doing the find validates that the id does actually correspond to a real object. You might consider skipping it for something that's really on the hot path but I really wouldn't do that from the outset.
