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

If you want to check if an object is within in array by checking an attribute on the object, you can use any? and pass a block that evaluates to true or false:

unless @suggested_horses.any? {|h| h.id == horse.id }
  @suggested_horses << horse
end
