Test for string in string

Rails

Hi,

Is there an easy way to test if a substring exists in a string?

I’m using this check:
if mystring.index(substring) > 0

but it doesn’t seem to be working…

Thanks!

‘foobar’.include? ‘foo’ #=> true
‘foobar’.include? ‘sup’ #=> false

index returns nil if it fails to find a match, not -1 like in Java.
So you can just test for true/false.

if mystring.index(substring)
…
end

I believe you should be able to use:

mystring.index.include? substring

That should return true of the string contains the substring
