SQLAlchemy操作數據庫建表時,無法像Django一樣提供choice方法,我們開頭導入SQLAlchemy-Utils來為我們提供這個功能

pip3 install sqlalchemy-utils

from sqlalchemy_utils import ChoiceType

            Base = declarative_base()


            class Xuan(Base):
                __tablename__ = ‘xuan‘
                types_choices = (
                    (
 
1,‘歐美‘),
                    (2,‘日韓‘),
                    (3,‘國產‘),
                )
                id = Column(Integer,primary_key=True,autoincrement=True)
                name = Column(String(64))
                types = Column(ChoiceType(types_choices,Integer()))

                __table_args__
 
 = {
                    ‘mysql_engine‘:‘Innodb‘,
                    ‘mysql_charset‘:‘utf8‘,
                }

查詢：

result_list = session.query(Xuan).all()
            for item in result_list:
                    print(item.types.code,item.types.value)

SQLAlchemy-Utils，提供choice功能
