Could you write a function that handles the inserts/selects instead?
class MY_PICKLE():
@classmethod
def get(keyname):
pkldump = db(db.pickle_table.keyname == keyname).select().first()
return pickle.loads(pkldump.value)
@classmethod
def save(keyname, value):
pkldump = db(db.pickle_table.keyname == keyname).select().first()
if pkldump:
pkldump.update_record(value=pickle.dumps(value))
else:
db.picke_table.insert(keyname=keyname,value=pickle.dumps(value))
a_list = MY_PICKLE.get("listkey")
# do some stuff to list
MY_PICKLE.save("listkey", a_list)
