Hello!

• I have a folder named icons which has three subfolders - controllers, png and svg.
• In the initial folder, I have the file input.haml.
• In the subfolder controllers, I have file images_controller.rb

Here is the sample of input.haml:

%div{style:"background-color: #fff; color:#000; width: 256px"}
  %br/

  %p Using local images path in loop arrays
  - @images.each do |image|
    %img{:src => "png/#{image.split('/').last}.png", style:"height: 64px; width: 64px; padding: 5px;"}

And of images_controllers.rb:

before_filter :set_input, only: %w(new create)

def set_input
  @images = Dir.glob('/home/gusbemacbe/icons/png/*.png')
end

I ran haml input.haml output.html

But I got an error:

Exception on line 5: undefined method `each' for nil:NilClass
