Ruby string with '.' to snake case

I've got string 'client.status' which I want to convert to snakecase - client_status. Is there a quick way to do so?

I tried:

> 'client.status'.underscore
"client.status"

> 'client.status'.parameterize
"client-status"

> 'client.status'.parameterize('_')
Traceback (most recent call last):
        1: from (irb):81
ArgumentError (wrong number of arguments (given 1, expected 0))

When passing the separator, you need to provide it as the keyword argument.

'client.status'.parameterize(separator: '_')

For more information, the source of the code is:

# File activesupport/lib/active_support/core_ext/string/inflections.rb, line 190
  def parameterize(separator: "-", preserve_case: false)
    ActiveSupport::Inflector.parameterize(self, separator: separator, preserve_case: preserve_case)
  end
