Hello,
I have implemeted a TimestampField that maps betweem unixtimestamps and
datetime.datetime objects, so i can use Datetime in Django while not
having to convert all timestamps to datetime fields yet. I need that for
downwards compatibility for an old application that uses the same
database. The Plan is to use it until I can reimplement the old
application in django and afterwards switch to Datetime and DateFields
entirely.
from django.db.models.fields import DateTimeField, IntegerField, Field
from datetime import datetime
from time import mktime
class TimestampField(DateTimeField):
def get_internal_type(self):
return "IntegerField"
def _get_val_from_obj(self, obj):
try:
return datetime.fromtimestamp((getattr(obj,
self.attname)))
except:
return datetime.fromtimestamp(0)
def get_db_prep_save(self, value):
if type(value) is datetime:
value = int(mktime(value.timetuple()))
else:
value = int(value)
return Field.get_db_prep_save(self, value)
Can someone comment wether this is a "proper" approach or wether I'll
perhaps experience other problems with this solution?
Regards
