Thanks for all the suggestions. I ended up going with a modified
version of the "Heroku way", which seems to provide the most
flexibility when deploying.
Specifically, I'm using ENV variables for secrets, like this chunk in
environments/production.rb:
ActionMailer::Base.smtp_settings = {
:address => "smtp.sendgrid.net",
:port => 25,
:authentication => :plain,
:user_name => ENV['SENDGRID_USER'],
:domain => ENV['SENDGRID_DOMAIN'],
:password => ENV['SENDGRID_PASSWORD'],
}
I added a shim for cases (like nginx + Passenger) where passing ENV
variables is unwieldy. It's just another file included in
application.rb:
secrets_file = File.expand_path('../too_many_secrets', __FILE__)
require secrets_file if File.exists?(secrets_file + '.rb')
That way I can include a .template.rb file next door as a list of
secrets the app needs to know about.
Comments and refinements are welcome. Thanks again for the suggestions.
