Description
I've run into some problems serializing/deserializing datetime objects with timezones - in the end came up the this DIY solution:
import pytz
TIMEZONE_UTC = pytz.utc
TIMEZONE_BRAZIL = pytz.timezone("America/Sao_Paulo")
class BrazilianDatetimeField(rows.fields.DatetimeField):
@classmethod
def deserialize(cls, value):
value = str(value or "").strip()
if not value:
return None
dt = datetime.datetime.fromisoformat(value)
if dt.tzinfo is None: # Force naive to be UTC
dt = TIMEZONE_UTC.localize(dt)
dt = dt.astimezone(TIMEZONE_BRAZIL)
return dt
@classmethod
def serialize(cls, value):
if value is None:
return ""
return value.isoformat()
It'd be awesome if rows could handle timezones in more standard way.
