在sqlalchemy中使用association_proxy时，是否可以分配查询而不是列表？

Question

我有以下课程：

class Request(BaseMixin, Base):
    id = Column(Integer, primary_key=True)
    scan_title = Column(String)
    status = Column(String)
    ip = Column(String)
    option_title = Column(String)
    priority = Column(Integer)
    owner = Column(String)
    # servers = relationship('Request2Server', back_populates='request')
    servers = association_proxy('request_servers','server')

class Server(BaseMixin, Base):
    ip = Column(String, primary_key=True, autoincrement=False)
    servercmdb_id_fk = Column(Integer, ForeignKey('servercmdb.id'))
    servercmdb = relationship('ServerCMDB', backref=backref('servercmdb', uselist=False))
    last_report = Column(String)
    status = association_proxy('server_requests', 'statusk')


class Request2Server(AssocBaseMixin, Base):
    request_id_fk = Column(Integer, ForeignKey('request.id'), primary_key=True)
    server_ip_fk = Column(String, ForeignKey('server.ip'), primary_key=True)
    status = Column(String)
    data = Column(String)
    error = Column(String)
    request_rel = relationship('Request', backref='request_servers')
    server = relationship('Server', backref='server_requests')  #, backref='requests')

    def __init__(self, server=None):
        self.server = server

和代码：

from db_alchemy.tables import Request, Server, Request2Server
from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
Base = declarative_base()
e = create_engine("sqlite:///datafiles/data.sqlite")
Base.metadata.create_all(e)
Session = sessionmaker(bind=e)
session = Session()
Debugger connected.
r = Request(scan_title='R1')
s1 = Server(ip='IP1')
s2 = Server(ip='IP2')
s3 = Server(ip='IP2')
session.add_all([r,s1,s2,s3])
r.servers.append(s1)
r.servers.append(s2)
r.servers.append(s3)
r.servers
[<db_alchemy.tables.Server object at 0x7f3cc0527e80>, <db_alchemy.tables.Server object at 0x7f3cc0451630>, <db_alchemy.tables.Server object at 0x7f3cc05e87b8>]

我想知道是否可以替换列表：

[<db_alchemy.tables.Server object at 0x7f3cc0527e80>, <db_alchemy.tables.Server object at 0x7f3cc0451630>, <db_alchemy.tables.Server object at 0x7f3cc05e87b8>]

带有一些类似查询的对象，通过它我可以轻松访问过滤的数据。我知道有可能在经典关系中配置过lazy ='dynamic'，但是association_proxy会将其转为列表。

关联代理值：

r.servers
[<db_alchemy.tables.Server object at 0x7fd841a09278>, <db_alchemy.tables.Server object at 0x7fd841a09438>]

关系值

r.request_servers
<sqlalchemy.orm.dynamic.AppenderQuery object at 0x7fd841970080>

我想通过类似查询的对象来给association_proxy值，例如：

r.servers
<sqlalchemy.orm.dynamic.AppenderQuery object at 0x7fd841970080>
