In Ruby, how do I find out if a string is not in an array?

Question

In Ruby, how would I return true if a string is not in an array of options?

# pseudo code
do_this if current_subdomain not_in [\"www\", \"blog\", \"foo\", \"         


        

Answer 1

You can try exclude? method instead of include?

Example:

do_this if ["www", "blog", "foo", "bar"].exclude?(current_subdomain)

Hope this help...Thanks
