Not sure why you'd want to do that - if a has_many is returning nil (rather than an empty array) something has gone terribly, terribly wrong. Also, .blank? isn't proxied like .empty? is - blank? will load the association then call the method; empty? is defined in AssociationCollection to do a direct SQL query if the association isn't loaded, potentially skipping a bunch of unneeded object creation. Certainly not a big deal, but worth following the standard API for efficiency's sake. --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
