What is "file"? It must not be the original request.vars.photo you were
dealing with, as that was a string object. In any case, looks like "file"
is what we need, so you should now be able to use it in your original code
and have web2py automatically rename and save the file via the built-in
upload mechanism.
Note, looks like "file" is the expected cgi.FieldStorage object, so
file.file would be the actual file object, and file.filename would be the
original filename. You don't have to worry about that, though -- you can
just pass "file" in the insert method, and web2py will extract the file and
filename automatically.
