result = session.execute(‘insert into ***‘)
session.commit()
last_insert_id = result.lastrowid
注意:如果存在多个用户操作数据库,应保持每个用户或者每个请求线程拥有各自隔离的session

def test_add(other):
u = TestClass()
u.Other = other
session = database.get_session()
try:
session.add(u)
session.commit()
return u.Id
except:
return false
finally:
session.close()
ui = UserInfo(userName=‘user‘+str(random.randint(1,10000)))
print ui.userId
ui.save()
print ui.userId
应该第二次调用ui.userId 会得到返回值,但是,却没有。
非常奇怪
解决办法:
将IntegerField 换成 AutoField
