creating empty array of items - should be a quick simple one


You need to declare the empty array first.
@items_missing_images = []

But do not use the '@items_missing_images += item '
Use @items_missing_images.push(item)
or @items_missing_images << item

The += only works if you are adding an array to an array.


I probably should mention the best way to do what you are trying to
accomplish would be:

@items_missing_images = @items_all.reject { |item| FileTest.exist?
(item.image_name) }
