Revisit and set the default value for some environment variables

[hoangmirs]

Why

• The following variables are required when we deploy a Rails application from our template:

  MAILER_DEFAULT_HOST: "localhost"
  MAILER_DEFAULT_PORT: "3000"
  MAILER_SENDER: "Test <[email protected]>"
  AVAILABLE_LOCALES: "en"
  DEFAULT_LOCALE: "en"
  FALLBACK_LOCALES: "en"

• But they can be set a default value instead of setting them every time we set up the CD
• IMO, we can use the current value for them when we fetch the value in the code:

config.i18n.available_locales = ENV.fetch('AVAILABLE_LOCALES', 'en').split(',')

• Sometimes, we forget to set them when deploying, and then it fails but it will take time to investigate that issue with some new members.
