Convert Created Date format from database value

Well firstly, there really is no reason to create those fields. Those
fields are created automatically. In fact by also manually declaring them
you may introduce unpredictable behaviour.

Now on to your question. The answer is, it depends, and lots of ways. Do
you want a static conversion, i.e. always to Y-M-D or to honour the users
locale settings?

Anyway the common way is to use the time library and specifically the
functions strptime and strftime, although isoformat is another good way of
converting a time string to a time tuple. You end up with code that looks
something like time.strftime('%Y-%m-%d', time.strptime(create_date,
'%Y-%m-%d %H:%M:%S')) You will need import time at the top of your file.

First, although last in the code you use strptime to convert the string to a
time tuple, then you convert the tuple back to a string using strftime.

Fur further reference just look at the python standard library under time.
 You will also probably need to do further reading on the perm_read function
of the orm.

Thanks Graeme Gellatly

can u teach me how to write the code?
i wanted to convert the existing date value from the posgresql database.

Normally Created_date and Created_uid do not show in purchase order form, and i use the inherit method that i type up there to call the value from the database to show it on the purchase order form. But the problems is i wanted to change the date format from the database value that i called.

Thanks Graemen Gellatly :D
