Hi, I'm a newbie here, both python and app engine. a few questions:
I store some fields in DB, but when show message on Web, I need more
fields, most of them are calculated according to fields in DB, For now
I don't want to do the calculating on web, but when I add some fields
to the DB model class, the web dose not recognize them, all values are
None, what should I do?
For example, I have a class
class Event(db.Model) :
owner = db.UserProperty()
title = db.StringProperty()
content = db.StringProperty(multiline = True)
status = None
color = None
when showing events on web, I want 'color' and 'status', so after
retrieve the data from DB, I do the following:
for event in events :
logger.info(event.status)
logger.info(event.color);
event.create_time = datetime.now()
event.status = "Finished"
event.color = "green"
but on web, they are still None.
BTW: I have to add status and color in class, or these fields are not
recognized.
