What happened

在/api/v1/chat/dialogue/new中，请求我带上了user_name，但是查询的时候user_name是空的，并没有保存

我们看了下源码发现：
发起会话不会创建会话记录，user_name需通过/v1/chat/completions传递入库，但是接口里面对它做了重写覆盖，要改源码才能实现效果

What you expected to happen

希望可以通过user_name去查询不同用户的会话历史记录

How to reproduce

调用post接口，然后再调用query_page接口，就能发现该问题，是一个必现问题

@router.post("/v1/chat/completions")
async def chat_completions(
    dialogue: ConversationVo = Body(),
    flow_service: FlowService = Depends(get_chat_flow),
    user_token: UserRequest = Depends(get_user_from_headers),
):
    logger.info(...)
    
    # 优先使用前端传入的 user_name，如果没有才使用 token 中的 user_id
    if not dialogue.user_name:
        dialogue.user_name = user_token.user_id if user_token else None
    
    dialogue = adapt_native_app_model(dialogue)

This secentecne is import.

if not dialogue.user_name:
    dialogue.user_name = user_token.user_id if user_token else None
