How do I create a default avatar if the avatar file does not exist?

I used paperclip to let users upload their avatars. Everything works fine.

I want to show a default image if the user didn't upload an avatar. I used this code in my view: 

<%= 
    if File.exist?(user.avatar.url)
         image_tag user.avatar.url(:large)
    else
         image_tag "default-avatar.png"
    end
%>

but it doesn't show the default image.

I put the default-avatar.png in app/assets/images/. What am I doing wrong?

EDIT

I followed the instructions oldergod mentioned in comments, but still the uploaded avatars don't show up.

Solution

  • I finally put it to work, using user.avatar? like this: 

    <%= 
   if user.avatar?
      image_tag user.avatar.url(:large)
   else
      image_tag "default-avatar.png"
   end
%>

    I think the problem is that File.exist? needs a path, not a url or something.
