1. 课程列表页前端
1. 前端：新建三个组件
- LightCourse.vue
- FreeCourse.vue
- ActualCourse.vue
2 配置路由
ActualCourse:

2. 课程相关表
1. 课程分类表：跟课程一对多，一个课程分类，有很多个课程
2. 课程表（实战课课表）：
- 多种课程：免费，实战，轻课 ----》使用三张表
- 多种课程，字段可能有一样的，也有不一样的
- 我们的设计是：多个课程，多个表，以后再加别的课程，再加表即可
3. 章节表：一个课程，有很多个章节
4. 课时表：一个章节，有多个课时
5. 老师表：实战课，一门课，就是一个老师讲，一对多，一个老师可以讲多门课

2.1 补充
1. ForeignKey 的on_delete 参数：
'''on_delete 可以选择的参数
models.CASCADE # 级联删除，注意使用时机，用户和用户详情 课程和课程章节
models.SET_NULL # 删除分类，课程这个字段设置为空，要有null=True参数的配合
models.SET_DEFAULT # 删除分类，课程这个字段设置为默认值，要有 defalut=xx参数的配合
models.DO_NOTHING # 删除分类，课程这个字段什么都不做
models.SET(值,函数内存地址) # 删除分类，课程这个字段设置为写的值，或者执行内部传入的函数，函数返回值放在这
'''
2. ForeignKey 的db_constraint=False：
'''
如果 db_constraint=False 只逻辑外键，不建立物理外键 没有外键约束,如果这样设置，修改，新增速度快，可能会出现脏数据（程序层面控制）
连表查询没有任何区别，其他操作完全一致
'''
3. ForeignKey 的 related_name='coursechapters':
# 基于对象的跨表查：
正向： 对象.字段 course.course_category 根据课程拿到了课程分类对象， course_category在表内部，就是正向
反向： 对象.表名小写 对象.表名小写_set.all() 字段在表中没有，但是有关联关系
related_name：
为了替换原来基于对象的跨表查反向查询 表名小写 或 表名小写_set.all() 的
related_query_name
为了替换原来__连表查询，中表名小写，现在直接用related_query_name指定的字符串即可
录入数据：
3. 课程列表页接口
1. 课程分类接口
2. 查询所有课程
-1. 可以按人气（学生人数）和价格排序
-2. 可以按课程分类过滤
-3. 带分页（基本分页）
3.1 查询所有分类接口
路由：
router.register('category', CourseCategoryView, 'category')
视图类：
class CourseCategoryView(GenericViewSet, CommonListModelMixin):
queryset = CourseCategory.objects.filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseCategorySerializer
序列化类：
class BannerSerializer(serializers.ModelSerializer):
class Meta:
model = Banner
fields = ['id', 'image', 'link']
3.2 查询所有课程接口
路由：
# http://127.0.0.1:8000/api/v1/courses/actual/--- get
router.register('actual', CourseView, 'actual')
视图类：
class CourseView(GenericViewSet, CommonListModelMixin):

serializer_class = CourseSerializer
filter_backends = [OrderingFilter, DjangoFilterBackend]
ordering_fields = ['students', 'price']
filterset_fields = ['course_category']
# 分页
pagination_class = CommonPageNumberPagination
序列化：

4. 课程详情接口
思路一：直接在之前写好的查询所有课程的视图类上，配置一个类即可
class CourseView(GenericViewSet, CommonListModelMixin,CommonRetrieveModelMixin)：
返回的字段，跟详情，不太对应（详情中要求拿出所有章节和课时，但实际上只返回了4个课时）
序列化类---》重写个详情的序列化类即可---》视图类中重写 get_serializer_class(self):
思路二：直接在之前写好的查询所有课程的视图类上，配置一个类即可
课程详情页组件 created 中向后端发送两个请求
- 查询课程详情：字段缺一些
- 查询章节：按当前课程过滤出来的，只是当前课程的所有章节
课程详情接口视图类：
# 查询所有课程接口+课程详情接口
class CourseView(GenericViewSet, CommonListModelMixin,CommonRetrieveModelMixin):
queryset = Course.objects.filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseSerializer
filter_backends = [OrderingFilter, DjangoFilterBackend]
ordering_fields = ['students', 'price']
filterset_fields = ['course_category']
# 分页
pagination_class = CommonPageNumberPagination
配置的查询单条的类：
5. 所有章节接口
查询所有章节：带按课程过滤功能
视图类：
class CourseChapterView(GenericViewSet, CommonListModelMixin):
queryset = CourseChapter.objects.filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseChapterSerializer
filter_backends = [DjangoFilterBackend]
filterset_fields = ['course']
序列化类：
from .models import CourseSection, CourseChapter
from rest_framework import serializers
# 课时表
class CourseSectionSerializer(serializers.ModelSerializer):
class Meta:
model = CourseSection
fields = [
'id',
'name',
'orders',
'section_link',
'duration',
'free_trail'
]
# 章节表
class CourseChapterSerializer(serializers.ModelSerializer):
coursesections = CourseSectionSerializer(many=True)
class Meta:
model = CourseChapter
fields = [
'id',
'name',
'chapter',
'summary',
'coursesections' # 这个字段其实有，隐藏了，通过 章节.coursesections.all() 能拿到所有课时的 ，使用它做子序列化
]
路由：
# http://127.0.0.1:8000/api/v1/courses/chapter/--- get
router.register('chapter', CourseChapterView, 'chapter')

8. 课程详情前台
1. 视频播放，借助于第三方的视频播放器组件
- 下载组件
cnpm install --save vue-core-video-player
- main.js中配置
- 在组件上（课程详情组件）
- js数据：
- 暂停和播放方法：
2. 详情页面，发送两个请求
获取课程信息：
获取章节信息：

9. 视频托管
1. 课程详情页面，有很多视频，就是文件 ----> 可以将文件放到项目中，media目录下
2. 静态资源：图片，视频 ----> 放到第三方
3. 第三方托管平台：（付费）
- 阿里 oss 对象存储
- 七牛云 存储
4. 自己搭建文件存储（ceph，fastdfs，minio）
- 访问
- fastdfs搭建参考文档：https://zhuanlan.zhihu.com/p/372286804
七牛云存储，托管视频
- 手动上传的视频
- 自动上传：
- python
- js上传：vue端直接上传上去
阿里云存储：
https://help.aliyun.com/zh/oss/developer-reference/simple-upload-1?spm=a2c4g.11186623.0.i1#concept-88426-zh
七牛云上传步骤参考文档：https://developer.qiniu.com/kodo/1242/python
python中：
from qiniu import Auth, put_file, etagimport qiniu.config #需要填写你的 Access Key 和 Secret Key access_key = ''secret_key = '' #构建鉴权对象 q = Auth(access_key, secret_key) #要上传的空间 bucket_name = 'lqz-luffy' #上传后保存的文件名key = '致命诱惑.mp4' #生成上传 Token，可以指定过期时间等token = q.upload_token(bucket_name, key, 3600) #要上传文件的本地路径localfile = './致命诱惑.mp4'ret, info = put_file(token, key, localfile, version='v2') print(info)assert ret['key'] == keyassert ret['hash'] == etag(localfile)
10. Header.vue 搜索form
在Header.vue中添加以下：
html :

methods：
11.搜索后台接口
搜索接口：在公司中是最难，最有技术含量的接口
搜索接口：可以搜索好多内容，搜的好多内容，一次性返回，前端根据不同key，渲染在不同位置
搜索 全去数据库搜索 -----> 数据量越来越大，搜了好多表，速度很慢 -----> 数据不放在数据库中 -----> 分布式全文检索引擎 -----> 搜索快，推荐
视图类：
# 搜索课程接口
from rest_framework.filters import SearchFilter
from utils.common_response import APIResponse
from .models import Teacher
class CourseSearchView(GenericViewSet, CommonListModelMixin):
queryset = Course.objects.filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseSerializer
filter_backends = [SearchFilter]
search_fields = ['name', 'price']
pagination_class = CommonPageNumberPagination
# 只在搜实战课----》还要能搜出老师信息，免费课信息，轻课信息。。。
# def list(self, request, *args, **kwargs):
# # 只是 实战课内容 res.result.result---->[]
# res=super().list(request, *args, **kwargs)
# # 搜索老师
# search=request.query_params.get('search')
# teacher_list=Teacher.objects.filter(name__contains=search)
# # 序列化 []
#
# # 搜免费课

#

12. 搜索功能前端
