Capistrano 3, Rails 4, database configuration does not specify adapter

Question

When I start

cap production deploy

it fails like this:

DEBUG [4ee8fa7a] Command: cd /home/deploy/myapp/releases/         


        

Answer 1

Using Cap 3 and capistrano_rails on rails 4 I was getting the same error; in the environment file(s) being deployed, I set

set :stage, :production
set :rails_env, 'production' # even though doc says only need to do this if it's different
