I’ve been using ActiveRecord and ActionMailer outside Rails.
Versions: 4.1.7
Recently wanted to update to 4.2.0 and got an issue:
NoMethodError: undefined method env' for Rails:Module/Users/user/.rvm/gems/ruby-2.1.2/gems/activerecord-4.2.0/lib/active_record/connection_handling.rb:3:in block in module:ConnectionHandling’
I’ve also commented in the commit, so you can have a look for more info
there.
