1.项目介绍
今日内容:(路飞项目) 1 contentType组件: 路飞学成项目，有课程，学位课（不同的课程字段不一样），价格策略 问题，1 如何设计表结构，来表示这种规则 2 为专题课，添加三个价格策略 3 查询所有价格策略，并且显示对应的课程名称 4 通过课程id，获取课程信息和价格策略 2 创建vue项目(目录结构介绍) 1 node.js 安装 2 vue脚手架:npm install -g @vue/cli 3 vue create 项目名字 4 用pycharm开发vue的项目 5 项目目录结构: -node_modules 项目依赖 -public 单页面开发(index是主页) -src ---开发项目就跟它打交道 -assets 放静态文件 -components 放组件的 -views 放的也是组件,但是他是页面组件 -App.vue 主页面 -main.js 项目主js(所有的配置,需要在里面写),入口 -router.js 路由配置相关 -store.js vuex组件相关的,状态管理器 -package.json 项目所有的依赖 6 一个组件中,都会有三部分: -template 模板 -script 写js代码 -style 写样式 7 element-ui -npm install element-ui - 3 vue跟django数据通信(axios) -npm install axios 4 vue操作cookie并保存 npm install vue-cookies 5 登陆接口 6 课程列表 -vue路由携带参数跳转 前面加一个冒号:后面传一个字典,指定name:路由的名字,params:是携带的参数 <router-link :to="{name:'coursedetail',params:{'id':course.id}}"> {{course.name}} </router-link> 7 课程详情页面

1、models. 2、APIView 3、ViewSetMixin 4、serializers 5、response 6、utils ------response
2、models
