课程板块
课程板块相关表分析及创建
课程板块创建表数据
-
课程类型
1.免费课
2.实战课
Python7天入门，django从入门到精通
3.轻课
整一套课程的线上内容，线上+线下结合 价格更高
-
建表思路
有个课程表，通过类型字段区分是不同的课，但是三种课的字段可能不一样
每一种课设计一张表：
FreeCourse
Course
LightCourse -
课程板块相关数据表的关联关系
CourseCategory 课程分类表 跟课程是一对多：一个分类下有多个实战课 Course 实战课程表 Teacher 老师表 一对多，一个老师可以录多门课程 CourseChapter 章节表 章节和课程，一对多 一个课程对多个章节 CourseSection 课时表 课时跟章节，一对多，一个章节有多个课时 -
创建课程app，创建表，迁移表
创建表字段course/model.py
