Redmine

Now we use a ugly hack to make that only the admin can delete attachment:

diff --git a/app/views/attachments/_links.html.erb b/app/views/attachments/_links.html.erb
index 0804b80..bfe351d 100644
--- a/app/views/attachments/_links.html.erb
+++ b/app/views/attachments/_links.html.erb
@@ -13,7 +13,7 @@
   <% end %>
   <%= " - #{attachment.description}" unless attachment.description.blank? %>
   <span class="size">(<%= number_to_human_size attachment.filesize %>)</span>
-  <% if options[:deletable] %>
+  <% if User.current.admin? && options[:deletable] %>
     <%= link_to image_tag('delete.png'), attachment_path(attachment),
                                          :data => {:confirm => l(:text_are_you_sure)},
                                          :method => :delete,
