一、项目简介

该系统具备管理员和用户两个主要功能模块。管理员可以管理系统首页、个人中心、用户、花卉种类、花卉信息、自助订花、系统管理、订单管理等。用户则允许查看和编辑个人信息、修改密码以及管理收藏的花卉。

二、系统设计

2.1软件功能模块设计

系统总体功能如图4-1所示。

2.2数据库设计

以下是将“商城资讯、收藏、用户、花卉信息评论、系统简介、关于我们”等作为实体，它们的局部E-R图，如图4-2所示：

三、系统项目部分截图

3.1系统功能实现

系统首页界面如图5-1所示：

花卉信息：在花卉信息页面的输入栏中输入花卉名称和价格进行查询，可以查看到花卉详细信息，并根据需要进行立即购买、添加到购物车、评论或收藏操作；花卉信息页面如图5-3所示：

个人中心：在个人中心页面可以对个人中心、修改密码、自助订花、我的订单、我的地址、我的收藏进行详细操作；个人中心页面如图5-4所示：

3.2后台管理员功能模块实现

在登录流程中，用户首先在Vue前端界面输入用户名和密码。这些信息通过HTTP请求发送到Python后端。后端接收请求，通过与MySQL数据库交互验证用户凭证。如果认证成功，后端会返回给前端，允许用户访问系统。这个过程涵盖了从用户输入到系统验证和响应的全过程。后台管理员登录页面如图5-5所示。

管理员进入主页面，主要功能包括对系统首页、个人中心、用户、花卉种类、花卉信息、自助订花、系统管理、订单管理等进行操作。管理员主页面如图5-6所示：

花卉信息功能实现是在Django后端部分，您需要创建一个新的应用，然后在该应用下创建一个模型（models.py）来定义花卉信息的数据结构，使用Django的ORM来处理与MySQL数据库的交互，包括花卉信息的查询、添加或删除等操作。接着，在views.py中编写视图逻辑来处理前端请求，使用Django的URL路由（urls.py）将请求映射到相应的视图函数。对于数据的验证和序列化，可以使用Django的表单或序列化器来实现。在前端Vue.js部分，将创建相应的Vue组件，在这些组件中使用axios或其他HTTP库与Django后端的API进行交互，实现花卉信息的查看、修改、查看评论或删除等功能。状态管理可以通过Vuex来维护，比如在store目录下定义花卉信息模块的状态、突变、动作和获取器。如图5-9所示：
