File_column shows path to the public

I am using

<% @entry = Entry.find(params[:id]) %>
<%= image_tag url_for_file_column(‘entry’, ‘image’) %>

to show image info at my view.

it will show image AND PATH TO THE IMAGE, like,
/usr/local/my_path_to_rail_project/public/entry/entry_id/image_name,

How may I remove the path to the image?

Thanks.

My fault, the path comes from

<% for column in Post.content_columns %>

<%= column.human_name %>: <%=h @post.send(column.name) %>

Ignore my question please.
