像这个
<figure class="attachment attachment--<%= blob.representable? ? "preview" : "file" %> attachment--<%= blob.filename.extension %>">
<% if blob.representable? %>
<%= image_tag blob.representation(resize_to_limit: local_assigns[:in_gallery] ? [ 800, 600 ] : [ 1024, 768 ]) %>
<figcaption class="attachment__caption">
<% if caption = blob.try(:caption) %>
<%= caption %>
<% else %>
<span class="attachment__name"><%= blob.filename %></span>
<span class="attachment__size"><%= number_to_human_size blob.byte_size %></span>
<% end %>
</figcaption>
<% else %>
<%= link_to blob.filename, rails_blob_path(blob) %>
<% end %>
