這裡運用了後端重新整理頁面來實現使用者的一些操作，話不多說，直接上程式碼
首先咱們要先建立一個專案目錄
進入我們電腦cmd 終端中，我這裡使用的是gitbash，cd到我們的專案目錄中
接下來的操作非常重要
建立我們的專案名稱classMS(classmanage system)
models.py下定義我們的資料庫
**專案目錄下classMS *
__init__.py下配置我們資料庫
settings.py下配置：
urls.py下配置
**注意 myapply中的urls.py需要我們手動建立**
找到我們的應用myapply
urls.py下
views.py下 from django.shortcuts import render, redirect, reverse from django.http import HttpResponse, HttpResponseRedirect from django.views.decorators.csrf import csrf_exempt from .models import Grades, Students # Create your views here. # TODO: 這裡是主頁 def home_page(request): cookie = request.COOKIES.get('id') list_g = Grades.objects.all() if cookie: obj = list_g.get(id=cookie) gname = obj.gname else: gname = list_g[0].gname obj = list_g[0] list_s = Students.objects.filter(grade=obj) return render(request, 'classms/index.html', {'list_g': list_g, 'list_s': list_s}) # TODO: 新增班級 @csrf_exempt def add_grade(request): gname = request.POST['gname'] list_g = Grades.objects.filter(gname=gname) if not list_g: last_g = Grades.objects.last() if last_g: gid = str(int(last_g.gid) + 1) else: gid = '10001' obj = Grades(gid=gid, gname=gname) obj.save() return redirect(reverse('class_ms:home')) else: print('dd') return HttpResponse(u'班級已存在') # TODO; 新增學生 def add_stu(request): sname = request.POST['sname'] gname = request.POST['gname'] find_g = Grades.objects.filter(gname=gname) if find_g: last_s = Students.objects.all().last() if last_s: sid = str(int(last_s.sid)+1) else: sid = '20180001' obj = Students(sid=sid, sname=sname, grade=find_g[0]) obj.save() return redirect(reverse('class_ms:home')) else: print('ff') return HttpResponse(u'輸入的班級不存在') # TODO: 更改學生資訊 def update_stu(request): sid = request.POST['sid'] sname = request.POST['sname'] gname = request.POST['gname'] find_g = Grades.objects.filter(gname=gname) if find_g: Students.objects.filter(sid=sid).update(sname=sname, grade=find_g[0]) return redirect(reverse('class_ms:home')) else: return HttpResponse(u'輸入的班級不存在') # TODO: 刪除學生 def delete_stu(request): sid = request.GET.get('pk') res = Students.objects.filter(sid=sid) if res: res.delete() return redirect(reverse('class_ms:home')) else: return HttpResponse(u'刪除失敗') # TODO: cookie切換班級 def change_grade(request, id): res = HttpResponseRedirect(reverse('class_ms:home')) res.set_cookie('id', id, 50) return res
