Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v2.2.1) is shown here.

These similar methods exist in v7.1.3.2:

ActionDispatch::Http::URL#subdomains

subdomains(tld_length = 1) public

Returns all the \subdomains as an array, so ["dev", "www"] would be returned for "dev.www.rubyonrails.org". You can specify a different tld_length, such as 2 to catch ["www"] instead of ["www", "rubyonrails"] in "www.rubyonrails.co.uk".
