How to set conditional variables in capistrano's deploy.rb?

[Saurav Shah]

Snippets from my deploy.rb

task :prod1 do
  set :deploy_to, "/home/project/src/prod1"
end

task :prod2 do
  set :deploy_to, "/home/project/src/prod2"
end

I have 2 tasks like the above. Now instead of manually running either "cap prod1 deploy" or "cap prod2 deploy", I want to create a task "prod" which sets the required "deploy_to" based on the existence of a file on the server.

something like:

task :prod do
  if (A_FILE_IN_SERVER_EXISTS)
    set :deploy_to, "/home/project/src/prod2"
  else 
    set :deploy_to, "/home/project/src/prod1"
end

How do I do that?

Use 'capture' with a find bash command

Then you can use the variable in your if
