[storm] what causes: storm.exceptions.LostObjectError: Can't obtain values from the database

[Steve Kieu]

Hello,

I have a simple script (attached to this email )- and evrytime I run, i got


stevek at lenovo:~/hang-hieu-uc/python$ python bulk_price_update.py
Number of record: 202
/usr/lib/python2.6/dist-packages/storm/database.py:342: Warning: Data
truncated for column 'amount' at row 1
  return function(*args, **kwargs)
Traceback (most recent call last):

_set_values
    raise LostObjectError("Can't obtain values from the database "
storm.exceptions.LostObjectError: Can't obtain values from the database
(object got removed?)

I am stuck at new idea to fix it, please help

If I do not modify the product_discount_id of a product then it printed
values fine and create in the history table fine. First I directly modify
the  pt object, but then try to get a product again using pt.id, however it
does not help in both cases.

The DB is VirutalMart DB if it helps

Many thanks in advance
