FastAPI（七十二）实战开发《在线课程学习系统》接口开发 留言列表开发

之前我们分享了FastAPI（七十一）实战开发《在线课程学习系统》接口开发-- 查看留言，这次我们分享留言列表开发。

 列表获取，也需要登录，根据登录用户来获取对应的留言。逻辑梳理如下。

1.判断用户是否登录
2.根据登录用户查询留言列表
3.留言列表中要根据是留言回复，进行列表重组

我们根据逻辑去梳理下对应的crud

def get_message_list(db: Session, userid: int):
    return db.query(Message).filter(or_(Message.senduser.id == userid, Message.acceptusers.id == userid,Message.status==0)).all()

　　我们根据逻辑去开发对应的代码。

@usersRouter.get(path="/messagelist")
async def messagelist(user: UsernameRole = Depends(get_cure_user),
                      db: Session = Depends(get_db)):
    users = get_user_username(db, user.username)
    messagelist = get_message_list(db=db, userid=users.id)
    message_list = []
    mainmessage = []
    if len(messagelist) > 0:
        for item in messagelist:
            if item.pid == "":
                messageone = MessageOne(id=item.id,
                                        senduser=get_user(db,item.senduser).username,
                                        acceptusers=get_user(db,item.acceptusers).username,
                                        read=item.read,
                                        sendtime=item.sendtime,
                                        addtime=str(item.addtime),
                                        context=item.context)
                mainmessage.append(messageone.id)
                all_pid = get_pid_message(db, item.id)
                if len(all_pid) > 0:
                    allpidlist = []
                    for items in all_pid:
                        message = MessagePid(id=item.id,
                                             senduser=get_user(db,items.senduser).username,
