sixteen_课程分页_课程详情页显示
2. 课程表分页
实现理论：
后端：继承rest分页函数自定义分页字段类，CourseAPIView类再调用该类即可完成后端分页
前端：前端利用element工具进行底部页码实现，: 为动态参数接收 @为绑定事件，设置:current_page 和 :page-size 和 :total 来实现页码的动态变化，watch监听动态切换数值及请求数据，请求数据，并重置页面即可
# 后端视图 from rest_framework.pagination import PageNumberPagination class StandardPageNumberPagination(PageNumberPagination): page_size_query_param = 'page_size' max_page_size = 1 class CourseAPIView(ListAPIView): queryset = Course.objects.filter(status=0).order_by("-orders","-students") # 设置过滤的字段 filter_fields = ('course_category',) serializer_class = CourseSerializer filter_backends = [OrderingFilter] ordering_fields = ('id', 'students', 'price', 'course_category') pagination_class = StandardPageNumberPagination
# 前端请求数据 <template> <div class="course"> <Header/> <div class="main"> <!-- 筛选功能 --> <div class="top"> .... <!-- 课程列表 ---> <div class="list"> 。。。。 </div> <div class="pagination"> <!-- 必须设置page-size属性，total值的改变才会有效果 --> <el-pagination @current-change="handleCurrentChange" :current-page="query_params.current_page" background layout="prev, pager, next" :page-size="course_page_size" :total="course_count"> </el-pagination> </div> </div> <Footer/> </div> </template> <script> import Header from "./common/Header" import Footer from "./common/Footer" export default { name: "Course", data(){ return { catetory_list:[], course_list:[], course_count: 0, course_page_size:1, query_params:{ course_category: 0, ordering:"-id", current_page: 1, } } }, watch:{ // 每次点击不同课程时,要重新获取课程列表 "query_params.course_category":function(){ this.get_course_list(); // 当切换分类的时候,重置页码 this.query_params.current_page = 1; }, "query_params.ordering":function(){ // 当切换排序条件的时候,重置页码 // this.query_params.current_page = 1; this.get_course_list(); }, "query_params.current_page":function(){ this.get_course_list(); } }, components: {Header, Footer}, created(){ // 获取课程分类 this.$axios.get(this.$settings.Host+"/courses/cate/").then(response=>{ this.catetory_list = response.data }).catch(error=>{ console.log(error.response) }); // 获取课程信息 this.get_course_list() }, methods:{ select_ordering(selector){ // 默认排序 if(this.query_params.ordering==('-'+selector) ){ this.query_params.ordering = selector; }else{ this.query_params.ordering = '-'+selector; } }, get_course_list(){ let query_params = { ordering:this.query_params.ordering, page:this.query_params.current_page, }; if( this.query_params.course_category != 0 ){ query_params.course_category = this.query_params.course_category; } this.$axios.get(this.$settings.Host+"/courses/list/",{ params: query_params }).then(response=>{ // 课程列表 this.course_list = response.data.results; // 课程总数量 this.course_count = response.data.count; }).catch(error=>{ console.log(error.response) }); }, handleCurrentChange(page){ // 页码发生改变 this.query_params.current_page = page; } } } </script> <style scoped> ... .pagination{ text-align: center; margin: 20px 0px 50px 0px; } </style>
3. CKEditor富文本编辑器
# 1. 安装 pip install django-ckeditor # 2. 添加应用，在dev.INSTALLED_APPS中添加 INSTALLED_APPS = [ ... 'ckeditor', # 富文本编辑器 'ckeditor_uploader', # 富文本编辑器上传图片模块 ... ] # 3. 添加CKEditor设置，在settings/dev.py中添加 # 富文本编辑器ckeditor配置 CKEDITOR_CONFIGS = { 'default': { 'toolbar': 'full', # 工具条功能 'height': 300, # 编辑器高度 # 'width': 300, # 编辑器宽 }, } CKEDITOR_UPLOAD_PATH = '' # 上传图片保存路径，留空则调用django的文件上传功能 # 4. 添加ckeditor路由，在总路由中添加 path(r'^ckeditor/', include('ckeditor_uploader.urls')), # 5. 为模型类添加字段，ckeditor提供了两种类型的Django模型类字段 - ckeditor.fields.RichTextField 不支持上传文件的富文本字段 - ckeditor_uploader.fields.RichTextUploadingField 支持上传文件的富文本字段\ # 修改course/models.py里面的字段信息,记得要重新数据迁移 from ckeditor_uploader.fields import RichTextUploadingField class Course(models.Model): """ 专题课程 """ ... brief = RichTextUploadingField(max_length=2048, verbose_name="课程概述", null=True, blank=True)

4. 课程详情页显示
因为接下来的组件中使用了vue-video视频播放组件，所以我们需要先预安装。
# 安装依赖 npm install vue-video-player --save # 在main.js中注册加载组件 require('video.js/dist/video-js.css'); require('vue-video-player/src/custom-theme.css'); import VideoPlayer from 'vue-video-player' Vue.use(VideoPlayer);
# 新建一个文件做详情页展示，Detail.vue组件代码： <template> <div class="detail"> <Header></Header> <div class="warp"> <div class="course-info"> <div class="warp-left" style="width: 690px;height: 388px;background-color: #000;"> </div> <div class="warp-right"> <h3 class="course-title">Python开发21天入门</h3> <p class="course-data">37400人在学 课程总时长：154课时/30小时 难度：初级</p> <div class="preferential"> <p class="price-service">限时免费</p> <p class="timer">距离结束：仅剩 28天 14小时 10分 <span>57</span> 秒</p> </div> <p class="course-price"> <span>活动价</span> <span class="real-price">¥0.00</span> <span class="old-price">¥9.00</span> </p> <div class="buy-course"> <p class="buy-btn"> <span class="btn1">立即购买</span> <span class="btn2">免费试学</span> </p> <p class="add-cart"> <img src="../../static/images/cart.svg" alt="">加入购物车 </p> </div> </div> </div> <div class="course-tab"> <ul> <li class="active">详情介绍</li> <li>课程章节 <span>(试学)</span></li> <li>用户评论 (83)</li> <li>常见问题</li> </ul> </div> <div class="course-section"> <section class="course-section-left"> <img src="../../static/images/21天01_1547098127.6672518.jpeg" alt=""> </section> </div> </div> <Footer></Footer> </div> </template> <script> import Header from "./common/Header" import Footer from "./common/Footer" export default { name: 'CourseDetail', data(){ return { } }, components:{ Header, Footer, }, methods:{ }, created(){ } }; </script> <style scoped> .detail{ margin-top: 80px; } .course-info{ padding-top: 30px; width:1200px; height: 388px; margin: auto; } .warp-left,.warp-right{ float: left; } .warp-right{ height: 388px; position: relative; } .course-title{ font-size: 20px; color: #333; padding: 10px 23px; letter-spacing: .45px; font-weight: normal; } .course-data{ padding-left: 23px; padding-right: 23px; padding-bottom: 16px; font-size: 14px; color: #9b9b9b; } .preferential{ width: 100%; height: auto; background: #fa6240; font-size: 14px; color: #4a4a4a; display: -ms-flexbox; display: flex; -ms-flex-align: center; align-items: center; -ms-flex-pack: justify; justify-content: space-between; padding: 10px 23px; } .price-service{ font-size: 16px; color: #fff; letter-spacing: .36px; } .timer{ font-size: 14px; color: #fff; } .course-price{ width: 100%; background: #fff; height: auto; font-size: 14px; color: #4a4a4a; display: -ms-flexbox; display: flex; -ms-flex-align: end; align-items: flex-end; padding: 5px 23px; } .real-price{ font-size: 26px; color: #fa6240; margin-left: 10px; display: inline-block; margin-bottom: -5px; } .old-price{ font-size: 14px; color: #9b9b9b; margin-left: 10px; text-decoration: line-through; } .buy-course{ position: absolute; left: 0; bottom: 20px; width: 100%; height: auto; -ms-flex-pack: justify; justify-content: space-between; padding-left: 23px; padding-right: 23px; } .buy-btn{ float: left; } .buy-btn .btn1{ display: inline-block; width: 125px; height: 40px; background: #ffc210; border-radius: 4px; color: #fff; cursor: pointer; margin-right: 15px; text-align: center; vertical-align: middle; line-height: 40px; } .buy-btn .btn2{ width: 125px; height: 40px; border-radius: 4px; cursor: pointer; margin-right: 15px; display: inline-block; background: #fff; color: #ffc210; border: 1px solid #ffc210; text-align: center; vertical-align: middle; line-height: 40px; } .add-cart{ font-size: 14px; color: #ffc210; text-align: center; cursor: pointer; float: right; margin-top: 10px; } .add-cart img{ width: 20px; height: auto; margin-right: 7px; } .course-tab{ width: 100%; height: auto; background: #fff; margin-bottom: 30px; box-shadow: 0 2px 4px 0 #f0f0f0; } .course-tab>ul{ padding: 0; margin: 0 auto; list-style: none; width: 1200px; height: auto; display: -ms-flexbox; display: flex; -ms-flex-align: center; align-items: center; color: #4a4a4a; } .course-tab>ul>li{ margin-right: 15px; padding: 26px 20px 16px; font-size: 17px; cursor: pointer; } .course-tab>ul>.active{ color: #ffc210; border-bottom: 2px solid #ffc210; } .course-section{ background: #FAFAFA; overflow: hidden; padding-bottom: 40px; width: 1200px; height: auto; margin: 0 auto; } .course-section-left{ width: 880px; height: auto; padding: 20px; background: #fff; float: left; box-sizing: border-box; overflow: hidden; position: relative; box-shadow: 0 2px 4px 0 #f0f0f0; } </style>
