渴望在SQLAlchemy中加载部分关系

Question

我在两个模型之间有1：M的关系。我想急切地从我身边的M侧加载最后5个项目。

Answer 1

stmt = session.query(Address).\
                 limit(5).\
                 subquery()
adalias = aliased(Address, stmt)
for user, address in session.query(User, adalias).\
         join(adalias, User.addresses): 
     print user
     print address
