From 7bd85a8fc2d216a5e2b1d0380df572f782a54d1c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Valim?= Date: Sat, 26 Jun 2010 11:57:43 +0200 Subject: Work around the fact the JSON gem was overwriting to_json implementation for all Ruby core classes. This is required because the JSON gem is incompatible with Rails behavior and was not allowing ActiveModel::Errors to be serialized. So we need to ensure Rails implementation is the one triggered.
