功能概述

实现了类似 GitHub 的评论 emoji 反应系统,用户可以对评论进行情感表达。

主要特性

Backend 后端

  • ✅ 新增 CommentReaction 模型,支持 8 种 emoji(👍👎❤️😄🎉😕🚀👀)
  • ✅ 唯一约束确保每个用户对每条评论的每种 emoji 只能点一次
  • get_reactions_summary() 方法返回反应统计和用户列表
  • ✅ RESTful API 端点:
    • GET /comment/<id>/react - 获取统计(公开访问)
    • POST /comment/<id>/react - 切换反应(需登录)
  • ✅ 数据库迁移文件和 Admin 管理界面

Frontend 前端

  • ✅ 新增 reactionPicker.js Alpine.js 组件
  • ✅ SSR + API 混合架构(零额外首屏请求)
  • ✅ 美观的登录引导模态框(替代浏览器 alert)
  • ✅ Toast 通知系统
  • ✅ Hover tooltip 显示点赞用户列表
  • ✅ 完整的深色模式支持
  • ✅ 平滑的 CSS 动画效果

用户体验

  • 🎯 登录用户可以点击 emoji 添加反应,再次点击取消
  • 🎯 显示每种 emoji 的计数和当前用户的点赞状态
  • 🎯 鼠标悬停显示点赞用户名单(前5个+剩余数量)
  • 🎯 未登录用户点击显示美观的登录引导弹窗
  • 🎯 401 错误自动处理并重定向到登录页
  • 🎯 CSRF 保护和安全验证
  • 🎯 响应式设计,完美支持移动端

技术实现

架构设计

采用 SSR + API 混合架构

  • 初始数据通过 data-reactions 属性从服务器端渲染
  • 更新操作通过 API 完成,避免页面重载
  • 性能优化:避免了传统 API 方式的首屏额外请求

性能优化

  • ✅ 使用数据库索引优化查询性能
  • select_related 优化关联查询
  • ✅ SSR 初始数据,避免首屏额外 API 请求(50条评论从51个请求降到1个)

修改的文件

Backend

  • comments/models.py - 新增 CommentReaction 模型
  • comments/views.py - 新增 CommentReactionView API
  • comments/urls.py - 新增路由
  • comments/admin.py - 注册管理界面
  • comments/migrations/0005_commentreaction.py - 数据库迁移

Frontend

  • frontend/src/components/reactionPicker.js - 新增 Alpine.js 组件
  • frontend/src/main.js - 注册组件
  • frontend/src/styles/main.css - 新增动画样式

Templates

  • templates/comments/tags/comment_item_modern.html - 集成反应 UI
  • templates/share_layout/base.html - 添加认证状态标识
  • blog/templatetags/blog_tags.py - 新增模板过滤器

测试建议

  1. 登录用户点击 emoji,验证反应切换
  2. 未登录用户点击,验证登录引导弹窗
  3. 鼠标悬停验证用户列表 tooltip
  4. 验证深色模式下的样式
  5. 验证移动端响应式布局
  6. 验证 CSRF 保护和安全性
