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

Based on Marc's answer which definitely seems to be the right one,

you can workaround this until it is fixed upstream by adding this to your config/deploy.rb in the "namespace :deploy" block:

  desc 'Provision env before assets:precompile'
  task :fix_bug_env do
    set :rails_env, (fetch(:rails_env) || fetch(:stage))
  end

  before "deploy:assets:precompile", "deploy:fix_bug_env"

This will force loading the env and provisionning RAILS_ENV before assets:precompile is called.
