bundle exec rake assets:precompile - database configuration does not specify adapter

Question

After 24 hours of trying to find the problem with my app. I finally found the problem.

I ran

rake assets:precompile RAILS_ENV=production
         


        

Answer 1

Make sure you have some dummy production entry in your local config/database.yml file

production:
  <<: *default
  database: your_local_database_name

I've come across the same error in 2016 with Rails 4.2.6 and Capistrano 3.4. We were precompiling the assets during the deploy script just before uploading them together with the code, but rake assets:precompile needs some production entry, even if it's just a dummy one.
