# 删除 AI 对话轮次及关联提交 Implementation Plan > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. **Goal:** 学生可以在 AI 对话界面删除某一轮对话（一问一答），同时删除该 AI 回答自动生成的提交；反向亦然——从提交列表删提交时，同时删除关联的那对消息。 **Architecture:** 在 `prompt.Message`（assistant 消息）上加一个可空的 `OneToOneField` 指向 `submission.Submission`，在提交创建时由前端传入 `message_id` 完成关联。两个方向的级联删除都在接口层显式处理。前端在 PromptPanel 的每个对话轮次上显示删除按钮，点击后同时移除本地消息状态。 **Tech Stack:** Django Ninja, Django Channels (AsyncWebsocketConsumer), Vue 3, TypeScript, Naive UI --- ## 文件改动清单 | 文件 | 改动类型 | |------|----------| | `api/prompt/models.py` | 修改：新增 `submission` 字段 | | `api/prompt/migrations/0005_message_add_submission_fk.py` | 新建 migration | | `api/prompt/consumers.py` | 修改：`complete`/`init` 事件带 `message_id` | | `api/prompt/api.py` | 修改：新增 `DELETE /messages/{message_id}/pair` 端点 | | `api/prompt/tests.py` | 新建：后端接口测试 | | `api/submission/schemas.py` | 修改：`SubmissionIn` 加 `message_id` | | `api/submission/api.py` | 修改：create 关联消息；delete 级联删消息对 | | `client/src/store/prompt.ts` | 修改：`PromptMessage` 加 `id`；回调传 `messageId` | | `client/src/api.ts` | 修改：`Submission.create` 加 `messageId`；新增 `Prompt.deleteMessagePair` | | `client/src/pages/ChallengeDetail.vue` | 修改：`setOnCodeComplete` 传 `messageId` | | `client/src/components/ai/PromptPanel.vue` | 修改：消息分组 + 删除按钮 | --- ## Task 1：Message 模型添加 submission 外键 **Files:** - Modify: `api/prompt/models.py` - Create: `api/prompt/migrations/0005_message_add_submission_fk.py`（由 makemigrations 生成） - [ ] **Step 1: 修改 `api/prompt/models.py`，添加 `submission` 字段** 在 `Message` 类中，`prompt_level` 字段之后添加： ```python # api/prompt/models.py from django.db import models from django_extensions.db.models import TimeStampedModel from account.models import User from task.models import Task import uuid class Conversation(TimeStampedModel): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="conversations") task = models.ForeignKey(Task, on_delete=models.CASCADE, related_name="conversations") is_active = models.BooleanField(default=True, verbose_name="是否活跃") class Meta: ordering = ("-created",) def __str__(self): return f"{self.user.username} - {self.task.title}" class Message(models.Model): conversation = models.ForeignKey( Conversation, on_delete=models.CASCADE, related_name="messages" ) role = models.CharField(max_length=10) source = models.CharField(max_length=12, default="conversation") content = models.TextField() code_html = models.TextField(null=True, blank=True) code_css = models.TextField(null=True, blank=True) code_js = models.TextField(null=True, blank=True) created = models.DateTimeField(auto_now_add=True) prompt_level = models.IntegerField( null=True, blank=True, default=None, db_index=True, verbose_name="提示词层级" ) submission = models.OneToOneField( "submission.Submission", null=True, blank=True, on_delete=models.SET_NULL, related_name="source_message", ) class Meta: ordering = ("created",) def __str__(self): return f"[{self.role}] {self.content[:50]}" ``` - [ ] **Step 2: 生成 migration** ```bash cd api && uv run manage.py makemigrations prompt --name message_add_submission_fk ``` 预期输出： ``` Migrations for 'prompt': prompt/migrations/0005_message_add_submission_fk.py - Add field submission to message ``` - [ ] **Step 3: 运行 migration** ```bash uv run manage.py migrate ``` 预期输出：末行包含 `Applying prompt.0005_message_add_submission_fk... OK` --- ## Task 2：WebSocket Consumer 发送 message_id **Files:** - Modify: `api/prompt/consumers.py` - [ ] **Step 1: 修改 `consumers.py`，`save_message` 返回 Message 对象，`complete` 事件带 `message_id`，`init` 历史消息带 `id`** 完整替换 `api/prompt/consumers.py`： ```python import json from channels.generic.websocket import AsyncWebsocketConsumer from channels.db import database_sync_to_async from django.db.models import Count from .models import Conversation, Message from .llm import stream_chat, extract_code class PromptConsumer(AsyncWebsocketConsumer): async def connect(self): self.user = self.scope["user"] if self.user.is_anonymous: await self.close() return self.task_id = int(self.scope["url_route"]["kwargs"]["task_id"]) self.current_user_message = None await self.accept() self.conversation = await self.get_or_create_conversation() history = await self.get_history() await self.send(text_data=json.dumps({ "type": "init", "conversation_id": str(self.conversation.id), "messages": history, })) async def disconnect(self, close_code): if self.current_user_message: await self.delete_message(self.current_user_message) self.current_user_message = None async def receive(self, text_data): data = json.loads(text_data) msg_type = data.get("type", "message") if msg_type == "new_conversation": return prompt = data.get("content", "").strip() model = data.get("model", "") if not prompt: return self.current_user_message = await self.save_message("user", prompt) try: history = await self.get_history_for_llm() full_response = "" try: async for chunk in stream_chat(history, model=model): full_response += chunk await self.send(text_data=json.dumps({ "type": "stream", "content": chunk, })) except Exception as e: await self.send(text_data=json.dumps({ "type": "error", "content": f"AI 服务出错：{str(e)}", })) return code = extract_code(full_response) assistant_msg = await self.save_message("assistant", full_response, code) self.current_user_message = None await self.send(text_data=json.dumps({ "type": "complete", "code": code, "message_id": assistant_msg.id, # 新增 })) finally: if self.current_user_message: await self.delete_message(self.current_user_message) self.current_user_message = None @database_sync_to_async def get_or_create_conversation(self): conv = ( Conversation.objects.filter(user=self.user, task_id=self.task_id) .annotate(msg_count=Count("messages")) .order_by("-msg_count", "-created") .first() ) if not conv: conv = Conversation.objects.create(user=self.user, task_id=self.task_id) return conv @database_sync_to_async def delete_message(self, message): message.delete() @database_sync_to_async def save_message(self, role, content, code=None): return Message.objects.create( conversation=self.conversation, role=role, content=content, code_html=code.get("html") if code else None, code_css=code.get("css") if code else None, code_js=code.get("js") if code else None, ) @database_sync_to_async def get_history(self): messages = self.conversation.messages.filter(source="conversation") return [ { "id": m.id, # 新增 "role": m.role, "content": m.content, "code": { "html": m.code_html, "css": m.code_css, "js": m.code_js, } if m.role == "assistant" else None, "created": m.created.isoformat(), } for m in messages ] @database_sync_to_async def get_history_for_llm(self): messages = self.conversation.messages.filter(source="conversation") return [{"role": m.role, "content": m.content} for m in messages] ``` - [ ] **Step 2: 启动后端，手动验证 WebSocket `complete` 事件包含 `message_id`** ```bash cd api && uv run manage.py runserver ``` 在浏览器打开挑战页，发送一条 AI 消息，在 DevTools Network → WS 帧中确认 `complete` 事件有 `message_id` 整数字段，`init` 事件每条消息有 `id` 字段。 --- ## Task 3：Submission 创建时关联 message **Files:** - Modify: `api/submission/schemas.py` - Modify: `api/submission/api.py` - Create: `api/prompt/tests.py` - [ ] **Step 1: 在 `SubmissionIn` 里加 `message_id`** 修改 `api/submission/schemas.py`，在 `SubmissionIn` 末尾添加一行： ```python class SubmissionIn(Schema): task_id: int html: Optional[str] = None css: Optional[str] = None js: Optional[str] = None prompt: Optional[str] = None message_id: Optional[int] = None # 新增：关联的 assistant message pk ``` - [ ] **Step 2: 写失败测试** 新建 `api/prompt/tests.py`： ```python from django.test import TestCase from django.contrib.auth import get_user_model from task.models import Task from submission.models import Submission from prompt.models import Conversation, Message User = get_user_model() def _make_user(username="student1"): return User.objects.create_user(username=username, password="pw") def _make_task(): return Task.objects.create( title="Test Task", task_type="challenge", display=1, content="" ) class SubmissionMessageLinkTest(TestCase): def setUp(self): self.client.login(username="student1", password="pw") self.user = _make_user("student1") self.task = _make_task() self.conv = Conversation.objects.create(user=self.user, task=self.task) self.user_msg = Message.objects.create( conversation=self.conv, role="user", content="帮我做个按钮" ) self.asst_msg = Message.objects.create( conversation=self.conv, role="assistant", content="好的", code_html="", code_css="", code_js="" ) def test_create_submission_links_message(self): """POST /submission/ with message_id links the assistant message""" self.client.force_login(self.user) resp = self.client.post( "/api/submission/", data={ "task_id": self.task.id, "html": "", "css": "", "js": "", "message_id": self.asst_msg.id, }, content_type="application/json", ) self.assertEqual(resp.status_code, 200) self.asst_msg.refresh_from_db() sub = Submission.objects.filter(user=self.user, task=self.task).first() self.assertIsNotNone(sub) self.assertEqual(self.asst_msg.submission, sub) def test_create_submission_without_message_id(self): """POST /submission/ without message_id still works""" self.client.force_login(self.user) resp = self.client.post( "/api/submission/", data={"task_id": self.task.id, "html": "
