From 6b0e834a194d112585f41deba0a40780d68e38c6 Mon Sep 17 00:00:00 2001 From: Amiel Martin Date: Fri, 20 Jun 2014 15:49:27 -0700 Subject: [PATCH] Use #model_name on instances instead of classes This allows rails code to be more confdent when asking for a model name, instead of having to ask for the class.
