python做業學員管理系統(第十二週)

做業需求:

用戶角色，講師＼學員， 用戶登錄後根據角色不一樣，能作的事情不一樣，分別以下

講師視圖

　　管理班級，可建立班級，根據學員qq號把學員加入班級

　　可建立指定班級的上課紀錄，注意一節上課紀錄對應多條學員的上課紀錄， 即每節課都有整班學員上， 爲了紀錄每位學員的學習成績，需在建立每節上課紀錄是，同時 爲這個班的每位學員建立一條上課紀錄

　　爲學員批改爲績， 一條一條的手動修改爲績

學員視圖

提交做業

查看做業成績

一個學員能夠同時屬於多個班級，就像報了Linux的同時也能夠報名Python同樣， 因此提交做業時需先選擇班級，再選擇具體上課的節數

附加：學員能夠查看本身的班級成績排名

數據庫關聯示意圖：

思路解析：

按照數據庫關聯，操做班級教室分數和上課記錄

講師視圖
1.管理班級，可建立班級
　　操做class表，輸入classname後顯示如今有幾個課程幾個課程表，而後讓講師建立TeacheCourse關聯後才能建立班級
2. 根據學員qq號把學員加入班級
　　操做StudentTeachClass表，把qq號加入班級ID，而後顯示，課程，課程表，班級，學員，
3. 可建立指定班級的上課紀錄，注意一節上課紀錄對應多條學員的上課紀錄，即每節課都有整班學員上，爲了紀錄每位學員的學習成績，需在建立每節上課紀錄，同時爲這個班的每位學員建立一條上課紀錄
　　進入後顯示班級，根據進入時候的班級講師ID，操做teacherclass，操做teacher_course，找到對應的學生查看對應的班級的童鞋，操做RecordStudent
4. 爲學員批改爲績， 一條一條的手動修改爲績
　　1. 進入後顯示班級，根據進入時候的班級講師ID，操做teacherclass，操做teacher_course，
　　2. 查看StudentHomework，查看學生的做業
　　3. 爲學員一條一條修改爲績和建立上課記錄，操做RecordScore
學員視圖
1. 提交做業
　　顯示課程，班級，上課節數，提交做業，作成綁定
2. 查看做業成績
　　查看RecordScore
3. 一個學員能夠同時屬於多個班級，就像報了Linux的同時也能夠報名Python同樣， 因此提交做業時需先選擇班級，再選擇具體上課的節數
4. 附加：學員能夠查看本身的班級成績排名
　　操做recordscore
　　排名，讀取出全部的成績和姓名，而後進行排序
