Question

向数据库添加数据时出现错误。他说这源于历史。在旧方法中，我们将其设置为 default = datetime.now。是现在不同了还是我犯了另一个错误？

    Table("application", meta,
    Column('id', Integer, primary_key=True),
    Column('name', VARCHAR(80)),
    Column('password', VARCHAR(80)),
    Column('anaSayfa', VARCHAR(80)),
    Column('manuelSayfa', VARCHAR(80)),
    Column('varsayilanlar', VARCHAR(80)),
    Column('dinamik', VARCHAR(80)),
    Column('dinamikSayfa', VARCHAR(80)),
    Column('kitap', String(80)),
    Column('kalem', String(80)),
    Column('date', DateTime, nullable=False, default=datetime.now))       
    meta.create_all(engine)

这里是代码：

app = Table('application', meta).insert().values(name = isim,
password = request.form.get("password"),
anaSayfa = request.form.get("anaSayfa"),
manuelSayfa = request.form.get("manuelSayfa"),
varsayilanlar= request.form.get("varsayilanlar"),
dinamikSayfa = request.form.get("dinamikSayfa"),
dinamik = bool(request.form.get("dinamik")),
kitap = bool(request.form.get("kitap")),
kalem = bool(request.form.get("kalem"))
    )

   conn = engine.connect()
    result = conn.execute(app)

和错误：
