ActiveSupport::Inflector#underscore

Makes an underscored, lowercase form from the expression in the string.

Changes '::' to '/' to convert namespaces to paths.

  'ActiveModel'.underscore         # => "active_model"
  'ActiveModel::Errors'.underscore # => "active_model/errors"

As a rule of thumb you can think of +underscore+ as the inverse of
+camelize+, though there are cases where that does not hold:

  'SSLError'.underscore.camelize # => "SslError"
