Question

Rails: How can I add admin approve functionality where user uploaded images have to be approved before they are displayed on their profiles?

Answer 1

How about add a column to the user’s avatar that says admin_approved or something similar? Since you’re using ActiveAdmin, it should pick up the column (unless you’ve specified otherwise). You then add a check before displaying the image:

<%= user_images.each do |image| %>
   <% if image.admin_approved %>
     <%= image_tag image.url %>
   <% end %>
<% end %>
