问题 We've be using the activerecord-sqlserver-adapter gem with sqlserver 2008 and everything works great. We just tried to deploy our Rails 3 app against a new sqlserver 2014 db and I get an error that says: Currently, only 2005, 2008, 2010, 2011, and 2012 are supported.

问题 quick question about Heroku. My app is using a gem called opentok. To function outside of a "sandbox" mode, the app requires changing an API link in a gem file called opentok.rb. I did that locally and the app works fine. however, when I deploy to heroku, the app does not work because heroku looks at my gem file and gets the unmodified gem lib of opentok which then runs my app on the heroku server in sandbox mode. Is there a way I can access the opentok gem file (opentok.rb) on the heroku
