[Moin-devel] Re: new to theme modifying and need help

[greg]

OK.  I came up with a solution using what was in action.AttachFile. 
Not sure it's the best but it works.

        pagename = d['page_name'] # is this right?
        attach_dir = getAttachDir(request, pagename)
        files = []
        if os.path.isdir(attach_dir):
            files = os.listdir(attach_dir)

        add(link(request, quotedname + '?action=AttachFile',
                 _('Attachments', formatted=False) + " (%i)" % len(files)))

I also learned something new about python string interpolation.  Doh.
