Question

I need help with this…

I have a hash like this:

@ingredients = Hash.new
@ingredients[1] = "Biscottes Mini(recondo)"
@ingredients[2] = "Abadejo"
@ingredients[3] = "Acelga"
@ingredients[4] = "Agua de Coco"
@ingredients[5] = "Ajo"
@ingredients[6] = "Almidón de Arroz"
@ingredients[7] = "Anillos Con Avena Integral cheerios (nestle)"
@ingredients[8] = "Apio"

I need to search into that hash in order to find “Biscottes Mini(recondo)” when I write “scotte”

Some help?

Thk!

Answer 1

Why do you use a Hash here and not an Array? You do not seem to use other keys than integers.

Anyway, this solution works for both Array and Hashes:

search_term = 'scotte'
# you could also use find_all instead of select
search_results = @ingredients.select { |key, val| val.include?(search_term) } 
puts search_results.inspect
