Search if a value exists in a Ruby Array

Question

I currently have this:

cart = [{"40"=>[{"size"=>"1", "count"=>1, "variation"=>nil, "style"=>"3"}]}, {"40"=>[{"size"=>"2", "count"=>1, "variation"=>nil, "style"=>"3"}]}]

How do I search this array and find out if "40" exists?

Answer 1

Use Enumerable#any:

item_in_cart = cart.any? { |item| item.has_key?("40") } 
#=> true / false
