How to list all autoload paths in Rails

Question

How do you list all of the autoload paths in Rails?

In Rails console when I do this, it only lists the custom paths added to the config:

$ rails c
Loading          


        

Answer 1

You can access all the autoload paths through ActiveSupport::Dependencies.autoload_paths

Invoke it from console or run rails r 'puts ActiveSupport::Dependencies.autoload_paths' from command line.
