Rails app not working in production environment on local machin

Question

When in development env it is working fine, but when I run the app in production evn, it says We're sorry, but something went wrong. If you are the application owner check the logs for more information.

The production log says:

I guess the problem is in the production.rb configuration file: you should allow Puma to serve static files.

In production servers, static files are usually served by Nginx, but that's not the case if you run Puma on your local machine.

In order to do so, in your production.rb set this value to true (or create an ENV variable named RAILS_SERVE_STATIC_FILES):

config.public_file_server.enabled = true

Add gem rails_12factor to your Gemfile. This will add error logging and the ability for your app to serve static assets.

Remember to clobber your assets

RAILS_ENV=production rails assets:clobber RAILS_ENV=production rails assets:precompile

In config/webpacker.yml make extract_css option true for production:

extract_css: true

Then run the following command before starting the server in production mode:

RAILS_ENV=production rails assets:precompile
