File_column

Hello all, another rails newbie here.
I’m working on an project to simply upload pictures with some extra
information, I was able to get uploads working thanks to file_column,
however, a couple things are troubling me. First of all, according to
the file_column website, displaying images should go like this:

<%= image_tag url_for_file_column(“entry”, “image”) %>

However, instead of the image, the alt tag is shown, when looking at the
source, a “?” shows up behind the url that shouldn’t be there:

Dsc_1146_small

Any idea why it’s doing that?

My second question… how do I extract the filename (+extension) from the
url after uploading it with file_column?
I saw a couple methods before, but I imagine there’s a faster and
cleaner way using file_column since it’s made for it.

Thanks in advance for any tips!
