As I asked previously, don't top post. Thanks. > > comment.commenter is a nilclass !!! but <%= comment.commenter %> it > got #<User:0xa86725c> I think you must be mistaken, it cannot both be nil and User at the same time. As fred suggested, maybe some are ok and others are nil. Try using something like <%= comment.commenter.name if comment.commenter %> Also have a look at the Rails Guide on debugging. It will show you how to use ruby-debug to break into your code and inspect data and follow flow.
