In Capistrano using the Multi-stage extension I have two environments: prod and testing.
I need a few variables in testing.rb that are not needed in prod.rb and I want some of my tasks to be able to check if the variable is defined and use it if it is, but ignore it if it is not set.
So, in testing.rb I would have something like:
set :foo, 'bar'
prod.rb wouldn't have any reference to :foo since it doesn't need it. In one of my tasks, I would like to do something like:
if defined?(foo)
# do something with foo
else
# do something without foo
end
But I keep getting the error:
undefined local variable or method 'foo'
Is there a way to test for undefined global variables in the task? Or do I have to do something like:
set :foo, ''
In all my environments that don't need the :foo variable?
Try using exists?(:foo)
instead of defined?(foo)
, as recommended in the Capistrano docs.
