How can I detect if my code is running in the console in Rails 3?

Question

I have this code in an initializer:

if $0 == 'irb'
  # ...
end

It works fine with Rails 2.3 but in Rails 3 the value of $0 is 'script/rails' no matter if it was started with rails c or rails s. ARGV is an empty array. How can I detect if the application has been started with "rails c" or "rails console"?

Answer 1

You could try this perhaps

if defined?(Rails::Console)
  # in Rails Console
else
  # Not in Rails Console
end
