How to check whether a string contains a substring in Ruby

Question

I have a string variable with content:

varMessage =   
            \"hi/thsid/sdfhsjdf/dfjsd/sdjfsdn\\n\"


            \"/my/name/is/balaji.so\\n\"
                 


        

Answer 1

A more succinct idiom than the accepted answer above that's available in Rails (from 3.1.0 and above) is .in?:

my_string = "abcdefg"
if "cde".in? my_string
  puts "'cde' is in the String."
  puts "i.e. String includes 'cde'"
end

I also think it's more readable.

See the in? documentation for more information.

Note again that it's only available in Rails, and not pure Ruby.
