Hello,
trying to understand SQLObject (using ist with Turbogears), but I don't
get it to work properly.
Got the model:
class Worktime(SQLObject):
start = DateTimeCol()
end = DateTimeCol( default=None )
user = ForeignKey("User")
class User(SQLObject):
user_name = UnicodeCol(length=16, alternateID=True,
alternateMethodName='by_user_name')
email_address = UnicodeCol(length=255, alternateID=True,
alternateMethodName='by_email_address')
display_name = UnicodeCol(length=255)
password = UnicodeCol(length=40)
worktimes = MultipleJoin("Worktime")
This call results in an Error:
wt = Worktime.select(Worktime.q.user==identity.current.user)
" AttributeError: Worktime instance has no attribute 'user' "
I see the attribute :)
The strangest thing is, this error occures since an update to SO 0.9.2.
Before that, I was using SO 0.7.7, which didn't show that error, but
returned (with the same call) every row twice.
I don't get SQLObject, I thought it should speed up my development, but
I clearly does not.
Thanks a lot, for listening to my whinig :) , hope you can help me!
Sincerly,
Nicolas
