课程表管理系统

1.学生/教师用户登录界面

 

2.首页

 

3.课程详细

点击已有课程，可弹出课程详细数据。

 

4.保存csv功能

        点击保存csv按钮，可下载当前显示课表的csv格式文档。

5.管理员登录界面

 

6.管理员后台界面

        管理员通过后台可以对老师、学生、班级等数据表进行增删改查功能，同时管理员后台首页可以实时的对每个班级/老师的课程进行安排，还有简单的筛选搜索功能、导出csv功能、新增/删除/修改课表信息功能。

 

7.代码详解

• 数据库建模

        根据需求分析，总共建立了老师表、班级表、学生表、教室表、课程总表

• 表之间的关系

        学生表和班级表是一对多的关系，

        课程表和老师表是一对多的关系，

        课程表班级表是一对多的关系，

        课程表教室表是一对多的关系。

• 后台管理

        后台管理使用的Django的第三方ui库simpleui来美化后台界面，参数配置如下。

#settings.py
#后台logo
SIMPLEUI_LOGO=r'/static/favicon.ico'
#关闭simpleui广告
SIMPLEUI_HOME_INFO = False 
#后台首页
SIMPLEUI_HOME_PAGE = '/root_index'  
​
​
INSTALLED_APPS = ['simpleui',#注册simpleuiAPP，需要放到最前面'django.contrib.contenttypes','django.contrib.admin','django.contrib.auth','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','courseIndex',#注册courseIndexAPP
]

 list_display是后台管理界面需要显示出的字段

search_fields是后台参与搜索的字段

 ordering是参与排序的字段

#admin.py
from django.contrib import admin
# Register your models here.
from  .models import *
​
#后台名字
admin.site.site_title = "后台管理"
admin.site.site_header = "排课系统"
​
#注册老师表后台管理功能
@admin.register(Teacher)
class TeacherAdmin(admin.ModelAdmin):exclude = []list_display=['teacher_num','teacher_name']search_fields=['teacher_name']
#注册课程表后台管理功能    
@admin.register(CourseWeekData)
class CourseWeekDataAdmin(admin.ModelAdmin):exclude = []list_display = ['id','subject','week','teacher','Class','room','day','Section']ordering=['week','day','Section']search_fields=['week','teacher']
#注册班级表后台管理功能
@admin.register(BasicClass)
class BasicClassAdmin(admin.ModelAdmin):exclude = []search_fields=['class_name']
#注册教室表后台管理功能
@admin.register(Room)
class RoomAdmin(admin.ModelAdmin):exclude = []search_fields=['room_name']
#注册学生表后台管理功能
@admin.register(Student)
class StudentAdmin(admin.ModelAdmin):list_display=['student_num','student_name']exclude = []search_fields=['student_name']

pip install -r requirements.txt

• 修改数据库设置

#进入项目settings.py，修改数据库配置
DATABASES = {'default': {'ENGINE': 'django.db.backends.mysql','NAME': '数据库名','USER':'用户名','PASSWORD':'密码','HOST':'127.0.0.1','POST':'3306','OPTIONS': {'charset': 'utf8mb4'},}
}

• 迁移数据库

#进入项目目录
cd xxx
