sqlalchmey使用session的filter_by查詢數據

#encoding:utf-8
from sqldb import *

class Article(Base):
    __tablename__ = 'article'

    id = Column(Integer, primary_key=True)
    title = Column(String(50))
    author = Column(String(50))
    content = Column(String(12))
    
    def __repr__(self):
        return "<Article(title='%s', author='%s', content='%s')>" % (self.title, self.author, self.content)


Session = sessionmaker(bind=engine)
session = Session()
usr_info = session.query(Article).filter_by(title='1111').first()
print usr_info
