We have a rail 3.2.19 application running on ruby 1.9.3 and passenger 3.0.19. We upgraded ruby to 2.1.5 and passenger to 4.0.57 and ran into the following issues post deployment.
Some of the update queires generated had 0=0 instead of actual query’s where clause
Some of the select queries the realtion name in the where clause was missing.
Is rails 3.2 compatible with Ruby 2.1.5?
