skuid attachment file name extension
I am wondering if there is a way to get attachment file name extension so I can rename attachment file name with correct file extension as we cannot assure that everyone is only upload 1 type of file.
In skuid online tutorial,
.invoice is the file type for the attachment, but our user may upload more than 1 file type .doc, .pdf, .jpg and etc. How can I dynamically get the file name extension of the attachment they upload?
