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

You could try this perhaps

if defined?(Rails::Console)  # in Rails Consoleelse  # Not in Rails Consoleend

ruby-on-rails console ruby-on-rails-3

Many years later there is a better method to do this registering blocks to run for the console (using the railtie interface).

So in the initializer you can write:

Rails.application.console do  # your code hereend

The good think about this is that it also works for runner and it should also work with spring (but I didn't test that).
