Question

In my application I have the option for a user to upload an image for a profile picture through paperclip.

Want I want to do in the index.html.erb page is to display all users with their display pictures, and if they have not uploaded one then it should display a default picture.

Now I have tried coding it in but at the moment the users who have pictures have the displayed but those who don’t get nothing.

I have the following code in my user model:

def user_photo
  (photo.url.present?) ? photo.url : '/images/guest.png'
end

and the following code in my index.html.erb

<% for user in @users %>
 .............
  <%= image_tag user.user_photo, :height => 50, :width => 50 %>
 ..............
 <% end %>

Any ideas on what my problem might be?

Thanks

Have something like this in your user model:

has_attached_file :photo, 
    :default_url => '/images/guest.jpeg',
    :styles => { 
      :large => "300x300>",
      :thumb => "100x100>",
      :tiny  => "32x32>"
    }

The :default_url option is used if there is no attached file for a model. If a user doesn’t have any uploaded photo you could use this option to set a default photo to show.

In the view:

<%= image_tag @user.photo.url(:thumb) %>
