Can file names be changed on uploading with cffile?

Question

I am currently trying to create a page where bands can upload their own logos onto the site for use where it is needed. Currently, I have created something which allows a user to upload/delete a logo to the allocated directory. But what I want to do is rather than create a band_logo field, have it so the band logo file name becomes the band's id in the database. With this being unique it means I don't have the long-winded process of creating a field to save their logo name. I know there is a cffile action="rename" option but that is a more long-winded process of doing things.

Yes, if you provide the file name in the destination it will rename the file on upload.

<cffile action="upload" destination="/path/to/some/directory/#session.bandName#.jpg" ... />

See Renaming Files As They Are Uploaded (how CFFILE actually works)

BTW, searching google for "name file on cffile upload" found that article...

However, you still may want to use

<cffile action = "upload" ...>
 then 
<cffile action = "rename" ...>

Because unless you snag the file extension on the client side and pass it on to the server, hard coding the file extension could cause problems if they don't upload a .jpg or whatever extension you designate. It isn't that much code or overhead and it's safer.
