Check whether a string contains one of multiple substrings

Question

I\'ve got a long string-variable and want to find out whether it contains one of two substrings.

e.g.

haystack = \'this one is pretty long\'
needle1          


        

Answer 1

For an array of substrings to search for I'd recommend

needles = ["whatever", "pretty"]

if haystack.match(Regexp.union(needles))
  ...
end
