Method 1 can be easily generalized in a function that set the placeholder
for all sqlform fields and strip away all labels and comments:
def autoset_form_placeholders(form, form_labels=False, form_comments=False):
for f in form.fields:
if f == 'id':
pass
else:
form.custom.widget[f].update(_placeholder=f)
if not form_labels:
form.elements('.w2p_fl', replace=None)
if not form_comments:
form.elements('.w2p_fc', replace=None)
