paperclip check is have attachment

Rails Plugin: Paperclip Question

up vote 5 down vote favorite 2	How can I prevent the image tag that calls the associated image from displaying if no image is associated with the record? <%= image_tag @agent.avatar.url %> ...gives me the text "Missing" if there is no image associated with that agent. I want to test to see there is an image available first, then render the above tag if the test returns true. Better yet, is there anyway for me to specify a default image if no image is specifically provided? ruby-on-rails  ruby  plugins  paperclip link | flag asked  Nov 17 '08 at 21:13 neezer 1,340 1 14 30 87% accept rate
