如何在flask-sqlalchemy中过滤双倍多对多关系

from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy()

user_role = db.Table('user_role',
    db.Column('user_id', db.Integer, db.ForeignKey('user.id')),
    db.Column('role_id', db.Integer, db.ForeignKey('role.id'))
)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50))
    roles = db.relationship('Role', secondary=user_role, backref=db.backref('users', lazy='dynamic'))

class Role(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50))

# 查询拥有角色名为'admin'的用户
users = User.query.filter(User.roles.any(name='admin')).all()

# 查询同时拥有角色名为'admin'和'manager'的用户
users = User.query.filter(User.roles.has(Role.name.in_(['admin', 'manager']))).all()
