sqlalchmey使用session的filter_by查询数据

#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
