如何通过 Flask 中的单个请求从 2 个单独的表中获取信息？

如何解决如何通过 Flask 中的单个请求从 2 个单独的表中获取信息？

class posts(db.Model):
    __tablename__ = "posts"
    id = db.Column(db.Integer,primary_key=True)
    name = db.Column(db.String(100))
    postName = db.Column(db.String(100))
    postDescription = db.Column(db.String(500))
    postLike = db.Column(db.Integer)

class postComment(db.Model):
    __tablename__ = "postComment"
    id = db.Column(db.Integer,primary_key=True)
    postID = db.Column(db.Integer)
    senderName = db.Column(db.String(20))
    commentPost = db.Column(db.String(300))

class PostsSchema(ma.Schema):
    class Meta:
        fields = ('id','name','postName','postDescription','postLike')

class CommentsSchema(ma.Schema):
    class Meta:
        fields = ('id','postID','senderName','commentPost')

posts_schema = PostsSchema()
posts_schema2 = PostsSchema(many=True)

comments_schema = CommentsSchema()
comments_schema2 = CommentsSchema(many=True)

我是根据帖子表中的 id 得到的。

{"id":2,"name":"bahadir","postDescription":"descript","postLike":12,"postName":"slsl"}

我是根据评论表中的 id 得到的。

{"commentPost":"merhaba ben burak","id":2,"postID":2,"senderName":"burak"}

每当我给出 id 时，我都想先获取帖子，然后是上面的 postComment。 （postID 与 ID 相关联。）

    @app.route('/posts/<id>',methods=['GET'])
    def get_posts_id(id):
    
        #post = posts.query.get(id)
        comments = postComment.query.get(id)
    
        # I want to do this -> comments_schema + posts_schema . jsonify(post,comments)
#HOW CAN I DO
        return comments_schema.jsonify(comments)

我要来的数据是这样的：

    [[{"id":2,"postName":"slsl"}]
[{"commentPost":"merhaba ben burak","id":1,"senderName":"burak"},{"commentPost":"hello flask tryyyy","senderName":"hello"}]]

postID = id
