How do I check to see if my array includes an object?

Question

I have an array @horses = [] that I fill with some random horses.

How can I check if my @horses array includes a horse that is already incl

Answer 1

Arrays in Ruby don't have exists? method, but they have an include? method as described in the docs. Something like

unless @suggested_horses.include?(horse)
   @suggested_horses << horse
end

should work out of box.
