Capistrano environment variable

问题:

I saw this Capistrano: Can I set an environment variable for the whole cap session?

And I am using this to set my variable

  set :default_environment, self[:default_environment].
    merge('PAYPAL_SANDBOX' => 'true')

I print self[:default_environment] and I get PAYPAL_SANDBOX correctly set

However, how could I test if rails server is running with that variable set?, I think is not working, because in another part I have

ENV['PAYPAL_SANDBOX'] ? 'development' : Rails.env

and I am getting into second part of this sentence, I mean is taking Rails.env instead of development

回答1:

I solved it like this:

1. I created a file inside my server, just to mark it

   touch test_server
   

2. Inside an initializer

   TEST_SERVER = `ls ~/test_server`.present?
   

3. Then,

   TEST_SERVER ? 'development' : Rails.env

My solution was like this:

1. Set global variable

   set :my_number, 23

2. Get global variable

   puts "My number is #{fetch(:my_number)}"
