The "upload" argument of SQLFORM.grid can be a function that takes the value and returns a URL, but you are still stuck having to figure out the URL from the filename, which will require a database lookup per row of the grid. An alternative is to not display the default file column in the grid and instead use the "links" argument to generate a custom column with custom download links (see "links" under http://web2py.com/books/default/chapter/29/07/forms-and-validators#SQLFORM-grid-signature). Another option is to create a custom column using a virtual field.
