Rails server error secret_key

  • 772

I created an application with ruby on rails in rubymine. I made it on Windows pc and it worked. Now I transferred it to a pc with Ubuntu and I installed ubuntu using this tutorial. Now I am getting an error when I call rails server on localhost:3000 and when I go to that page in my browser.

Puma caught this error: Missing `secret_key_base` for 'development' environment, set this value in `config/secrets.yml` (RuntimeError)
/home/fangio/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/railties-5.0.3/lib/rails/application.rb:513:in `validate_secret_key_config!'

How can I fix this easily? I am an Ubuntu newbie.

    it clearly says what is missing and where. You need to open "config/secrets.yml" and add secret key for development enviorment

    U can generate random key using irb:

    irb
irb(main):001:0> require 'securerandom'
=> true
irb(main):002:0> SecureRandom.hex(64)
=>"6bb7bc01dd219ac9f074c26c4016260349f70d90f0c38ae171f2232a844bac54c0d6c6bae50eecdbcc73c828bd68076a5700449d069dc8e1ad5a43abd9386dca"

    irb(main):003:0>

    Then copy that long string into secret file
