Allow use of ENV variables for public/private keys

[joryhatton]

I'd like to store these values in environment variables instead of checking them into the repository. Is this possible with an alternative configuration method?

defaults: &defaults                                                              
  public_key: <%= ENV["UPLOADCARE_PUBLIC_KEY"] %>                                
  private_key: <%= ENV["UPLOADCARE_PRIVATE_KEY"] %> 

Just blows up.

what do you mean by blows up?

Private or public key options were not provided (ArgumentError)

I was able to get this working by providing a fallback string in config/uploadcare.yml. ENV vars load successfully, and it prevents the exception during initialization.

defaults: &defaults                                                              
  public_key: <%= ENV["UPLOADCARE_PUBLIC_KEY"] || 'asdf' %>                                
  private_key: <%= ENV["UPLOADCARE_PRIVATE_KEY"] || 'asdf' %>

@joryhatton, we have released a new 2.0.0 version. We moved keys settings to initializers, so you should be able to set them properly in v2.

❗ See migration guide, v2 is not backward compatible with v1
