Ruby Undefined Method each for NilClass Error

[charlotte]

Hi everyone,

I'm running into an issue with my Ruby code and I'm not sure how to fix it. I keep getting the following error:

undefined method `each` for nil:NilClass (NoMethodError)

Here is a simplified version of my code:

def print_items(items)
  items.each do |item|
    puts item
  end
end

my_items = nil
print_items(my_items)

I also check this : https://codeforum.org/tags/ergenairor/ But I have not found any error.

I understand that this error occurs because my_items is nil, but I'm not sure how to properly handle this situation. Should I be checking if items is nil before calling each, or is there a better way to handle this?

Any advice or suggestions on how to fix this error would be greatly appreciated!

Thanks in advance!

Yes you should be checking for nil if it can happen. You can easily do it like thus.
if (thing == nil)
#handle nil
else
#.each
end
#X E.
