Generating a new secrets.yml file

Question

I'm trying to clone a rails repository from github, but it doesn't have a secrets.yml file. When I try to run the app from rails server, I get the error

Missing secret_key_base for 'development' environment, set this value in config/secrets.yml

I know what the structure of the file is supposed to look like, but is there a way for me to generate keys to use the development environment?

Answer 1

This rake task generate secret for you:

bundle exec rake secret

Generate a cryptographically secure secret key (this is typically used to generate a secret for cookie sessions)

All rake tasks:

bundle exec rake -T 

The secrets.yml file(note the indentation):

development:
  secret_key_base: d140269c106b6d064cdd670a5aace0bbbb1400de545377a47836dbdab8104f2fdf0ab87e6b7982819d1bcc2ccf6a5f093985a0895970f01f30b0b15378a090e9
  some_key: 338a3312d82
  some_secret: f5d9c3214e7b
  other_environment: development
  other_password: password

production:
  secret_key_base: d140269c106b6d064cdd670a5aace0bbbb1400de545377a47836dbdab8104f2fdf0ab87e6b7982819d1bcc2ccf6a5f093985a0895970f01f30b0b15378a090e9
  some_key: 338a3312d82
  some_secret: f5d9c3214e7b
  other_environment: development
  other_password: password

Answer 2

In Rails 5 you can simply type.

rails secret

This will generate a new key for you. Just copy the key and put it in your secrets.yml file

development:
  secret_key_base: <Generated key>
