One option might be something like this:
for field in db.auth_user:
field.widget = lambda f, d, label=field.label: SQLFORM.widgets[f.type].
widget(f, d, _placeholder=label)
field.label = ''
That will set the placeholder for each field to the value of the label and
then set the label to an empty string so it won't display. Another option
is to use the formstyle argument to SQLFORM and write your own formstyle
function. It's not yet documented in the book, but formstyle can now be a
function that takes the form and a list of fields and returns the entire
form body (except the opening and closing form tags). For an example of
what the function should look like, see the one used for the "table3cols"
formstyle:
