Question

I know I can do

@somethings.each do |something|
/*some work with something*/
end

but I want to know if I can loop over @somethings with a for

I tried

for i in 0..10
    @somethings[i].myattribute
end

but it is not giving me the object I want, or any object as far as I know.

I need to use the for loop, I cannot do what I want with “each”. So is it possible to use a for loop somehow?

Answer 1

for something in @somethings
  something.myattribute
end

or weird

@somethings_array = @somethings.to_a
for i in 0..10
  @somethings_array[i].myattribute
end

ok

@somethings_array = @somethings.to_a
10.downto(1) do |i|
  @somethings_array[i].myattribute
end
