FYI
If someone tries to run your code on a fresh empty db,
then they need to first
create a record in the database
and im that case, the record would have id=1
and so in your code
def testdata():
setsubmit()
if request.args: id = request.args[0]
else: id = 3 # Included for testing
It should be
def testdata():
setsubmit()
if request.args: id = request.args[0]
else: id = 1 # default to read the first record
