Hi list,
For this problem I am even having trouble think of a proper subject for it.
I try my best to express as clear as possible and sorry for any confusions.
Say there are three classes with relationship defined as below:
class User(Base):
__tablename__ = 'users'
id = Column(Integer,
Hi list,
I am encountering a very strange error and I am scratching my head and got
no idea what is going on.
class Line(Base):
__tablename__ = 'lines'
id = Column(Integer, Sequence('line_id_seq'), primary_key=True)
start = Column(Geometry('POINT'), nullable=False, *index=False*)
For example,
session.query(User).filter(User.name == 'fred').first()
q = session.query(User).filter(User.name == 'fred')session.query(q.exists())
session.query(exists().where(User.name == 'fred')).scalar()
are they perform pretty much the same? or is there a better way for
checking?
Thanks
Hi all,
Say there are two tables defined as below:
class Topic(Base):
__tablename__ = 'topics'
id = Column(Integer,Sequence('topic_id_seq'), primary_key=True)
*last_posted_at=Column(DateTime,default=func.now())*
created_at=Column(DateTime,default=func.now())
Hi list,
currently I have two fields:
START = Column(DateTime,default=func.now())
END = Column(DateTime,default=func.now() + 30 )
apparently the default syntax in END field is not correct.
How do I set the default value of END field, say 30 days after the value of
START field?
thanks

I just tested it and it just worked like a charm. SQL crafting made easy!
Thanks Mike
