一、课程板块相关分析以及创建

  • 建表思路:有个课程表通过类型字段区分划分不同课,所以这三种课的表字段是是不一样的。

  • 一种课设计一张表

    FreeCourse 免费课程

    Course 实战课程:Python7天入门,django从入门到精通

    LightCourse 轻课:整一套课程线上内容,线上+线下结合,价格更高

  • 只写实战课:

    • 课程分类表①
    • 实战课程表②
    • 老师表③
    • 章节表④
    • 课时表⑤

    ①与②===》一对多,一个分类下多个课程

    ③与②===》一对多,一个课程有多个老师

    ④与②===》一对多,一个课程多个章节

    ⑤与②===》一对多,一个课程多个课时

  • 创建课程app,创建表,迁移表

二、课程板块,数据录入
