示例1: as_declarative

# 需要导入模块: from sqlalchemy.ext import declarative [as 别名]
# 或者: from sqlalchemy.ext.declarative import as_declarative [as 别名]
def as_declarative(**kw):
    """
    Class decorator for :func:`.declarative_base`.

    Provides a syntactical shortcut to the ``cls`` argument
    sent to :func:`.declarative_base`, allowing the base class
    to be converted in-place to a "declarative" base::

        from sqlalchemy.ext.declarative import as_declarative

        @as_declarative()
        class Base(object):
            @declared_attr

                return cls.__name__.lower()
            id = Column(Integer, primary_key=True)

        class MyMappedClass(Base):
            # ...

    All keyword arguments passed to :func:`.as_declarative` are passed
    along to :func:`.declarative_base`.
