From 430b252d3d9bcf12951c2c58b744e83d43a34223 Mon Sep 17 00:00:00 2001 From: David Heinemeier Hansson Date: Sat, 2 Nov 2013 19:56:58 -0700 Subject: Revert "ActiveRecord::Base#<=> has been removed. Primary keys may not be in order," -- will be replaced with a check to ensure that the keys used for comparison are integers, and only fail if they are not. This reverts commit 6256734e2d0bdd89f4b5d11da259d40afa0c95c7.
