Question

I have a rails 3 helper function. This function simply takes an array of ojects and return images based on the url in each object. For some reason, I cannot seem to print the images…I just get back the array.

for example:

def my_helper(items)
 items.each do |item|
   image_tag(item)
 end
end

this returns the array. I’ve tried assigning to a variable and outputting, but no luck. I’ve seen where people say just use item.join('<br/>') but I didn’t get that to work.

Help appreicated

This should work:

def my_helper(items)
  items.map do |item|
    image_tag(item)
  end.join('<br/>')
end
