Question

In my Capistrano’s deploy.rb file, I set up different environments such as server names, ports, etc. I also require the users to send a callback to another server, also defined in the deploy.rb. How do I cleanly pass this value to my app?

Something to this effect:

config/deploy.rb:

set :callback_url, "http://somecallbackurl.com:12345/bla"

app/controllers/myapp.rb:

def get_callback_url
   ???
end

I’m using Sinatra.

Answer 1

I found a solution, and that is to use the environment variables.

Set it from deploy.rb

run "export CALLBACK_URL=#{callback_url}"

From app:

def get_callback_url
    ENV['CALLBACK_URL']
end

I wouldn’t say it’s the cleanest solution, but it works.
