I’m new to Ruby and Rails from Coldfusion, and I am already finding how  
much easier Ruby programming is, yet one thing that I haven’t quite  
figured out how to do in Ruby is to test whether for example, a contains  
b. In Coldfusion we did , but I can’t seem to find a  
CONTAINS() function or operator in Ruby. What would be the Ruby  
equivalent of the code above? And How would I test if one var contains  
another, or another string? Thanks for your help and time.

if a.include? b

Check the documentation for Array and Hash.

Also works for strings, if that’s what you meant. (Don’t know  
Coldfusion).

Thanks, sorry for the stupid question, but hopefully I’ll get the hang  
of Ruby. You would consider CF as a relatively easy language, but it’s  
nothing like Ruby.
