undefined method `each' for

Question

I've got a HAML file which works:

%h2 
  #{@schedule_item.schedule_id}

and prints the ID.

I then try:

%h2 - @schedule_item.each do |test| %li test

and get the error: undefined method `each' ScheduleItem:0x007ff8b91c06b0

can someone explain why I can't run each on this instance variable?

Answer 1

each is a method that can be used on collection objects/Arrays

Although, i cannot see the reason you are iterating a single instance, however if you want to run each on single instance, you need to first cast it as an array like this.

%h2
  - Array(@schedule_item).each do |test|
    %li test
