Django_学生管理系统
一. Django简易学生管理系统
1.在pycharm中创建工程student_manage_system，添加app:student_manage
2.配置静态文件：在工程项目目录下新建目录static，并在settings.py中追加代码
STATICFILES_DIRS=(os.path.join(BASE_DIR,'static'),)
3.设计学生管理系统所需数据库
在studnet_manage/models.py创建班级管理表、学生管理表、老师管理表
from django.db import models # Create your models here.
class classes(models.Model):
title = models.CharField(max_length=32)
teacher = models.ManyToManyField("Teachers") class student(models.Model):
StudentName = models.CharField(max_length=32)
age = models.IntegerField()
gender = models.BooleanField()
cs = models.ForeignKey("classes",on_delete=models.CASCADE) class Teachers(models.Model):
TeacherName = models.CharField(max_length=32)
model.py
在终端Terminal 项目目录下执行数据表更新命令：
python manage.py makemigrations
python manage.py migrate
4.学生管理系统之班级管理
1.为了方便分别操作班级、老师、学生相关的业务，将student_manage目录下的views.py 删掉，在student_manage目录下新建目录views，并在views目录下 新建classes.py teachers.py students.py。
2.在classes.py 中写 get_classes， add_classes ，delete_classes ，edit_classes四个函数，完成对班级数据的增删改查
from django.shortcuts import render
from django.shortcuts import redirect
from student_manage.models import * def get_classes(request):
class_list = classes.objects.all()
return render(request,'get_classes.html',{'class_list':class_list}) def add_calsses(request):
if request.method == "GET":
return render(request, 'add_classes.html')
elif request.method == 'POST':
title = request.POST.get('title')
classes.objects.create(title=title)
return redirect('/get_classes.html')
def delete_classes(request):
nid=request.GET.get('nid')
classes.objects.filter(id=nid).delete()
return redirect('/get_classes.html')
def edit_classes(request):
if request.method=='GET':
nid = request.GET.get('nid','')
obj = classes.objects.get(id=nid)
return render(request,'edit_classes.html',{"obj":obj})
elif request.method=='POST':
nid = request.GET.get('nid','')
title = request.POST.get('title')
classes.objects.filter(id=nid).update(title=title)
return redirect('/get_classes.html')
classes.py
3.在urls.py 中配置url路由
from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from student_manage.views import classes,students,ajax urlpatterns = [
#path('admin/', admin.site.urls),
url('^get_classes.html$',classes.get_classes),
url('^add_classes.html$',classes.add_calsses),
url('^delete_classes.html$',classes.delete_classes),
url('^edit_classes.html$',classes.edit_classes),
]
urls.py
4.在templates目录下建立所需的html页面文件
<1>get_classes.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<div>
<a href="/add_classes.html">添加</a>
</div>
<table border="1">
<thead>
<tr>
<th>ID</th>

<th>任课老师</th>
<th>操作</th>
</tr>
</thead>
<tbody>
{% for row in class_list %}
<tr>
<td>
{{ row.id }}
</td>
<td>
{{ row.title}}
</td>
<td>
{% for item in row.teacher.all %}
<span>{{item.TeacherName}}</span>
{% endfor %}

5.学生管理系统之学生管理
1.在students.py 中写 get_students， add_students ，delete_students ,edit_students 四个函数，完成对学生数据的增删改查
from django.shortcuts import render
from django.shortcuts import redirect
from student_manage.models import * def get_students(request):
student_list=student.objects.all()
return render(request,'get_students.html',{'student_list':student_list})
def add_students(request):
class_list = classes.objects.all()
if request.method == "GET":
return render(request, 'add_students.html',{'class_list':class_list})
if request.method == "POST":
StudentName=request.POST.get('StudentName','')
age=request.POST.get('age','')
gender=request.POST.get('gender','')
cs=request.POST.get('cs','')
student.objects.create(StudentName=StudentName,age=age,gender=gender,cs_id=cs)
return redirect('/get_students.html') def delete_students(request):
nid = request.GET.get('nid')
student.objects.filter(id=nid).delete()
return redirect('/get_students.html') def edit_students(request):
class_list = classes.objects.all()
if request.method == 'GET':
nid = request.GET.get('nid','')
obj = student.objects.get(id=nid)
print("class_list:",class_list)
return render(request,'edit_students.html',{"class_list":class_list,"obj":obj})
if request.method == 'POST':
nid = request.GET.get('nid','')
StudentName = request.POST.get('StudentName','')
age=request.POST.get('age','')
gender=request.POST.get('gender','')
cs=request.POST.get('class_id','')
print("class_id",cs)
student.objects.filter(id=nid).update(StudentName=StudentName,age=age,gender=gender,cs_id=cs)
return redirect('/get_students.html')
students.py
2.在urls.py 中配置url路由

6.学生管理系统之教师分配
1.在classes.py中增加教师分配函数set_teacher
from django.shortcuts import render
from django.shortcuts import redirect
from student_manage.models import * def get_classes(request):
class_list = classes.objects.all()
return render(request,'get_classes.html',{'class_list':class_list}) def add_calsses(request):
if request.method == "GET":
return render(request, 'add_classes.html')
elif request.method == 'POST':
title = request.POST.get('title')
classes.objects.create(title=title)
return redirect('/get_classes.html')
def delete_classes(request):
nid=request.GET.get('nid')
classes.objects.filter(id=nid).delete()
return redirect('/get_classes.html')
def edit_classes(request):
if request.method=='GET':
nid = request.GET.get('nid','')
obj = classes.objects.get(id=nid)
return render(request,'edit_classes.html',{"obj":obj})
elif request.method=='POST':
nid = request.GET.get('nid','')
title = request.POST.get('title')
classes.objects.filter(id=nid).update(title=title)
return redirect('/get_classes.html') def set_teacher(request):
if request.method=='GET':
nid = request.GET.get('nid','')
class_obj=classes.objects.get(id=nid)
class_teacher_list=class_obj.teacher.all()
all_teacher_list=Teachers.objects.all()
return render(request,'set_teacher.html',{'class_teacher_list':class_teacher_list,'all_teacher_list':all_teacher_list,'class_obj':class_obj})
elif request.method=='POST':
nid=request.GET.get('nid','')
ids_str=request.POST.getlist('teacher_id','')
# obj = classes.objects.get(id=nid)
# obj.teacher.set(ids_str)
obj = classes.objects.filter(id=nid).first()
obj.teacher.set(ids_str)
return redirect('/get_classes.html')
classes.py
2.在templates目录下建立所需的html页面文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="post" action="set_teacher.html?nid={{ class_obj.id }}">
{% csrf_token %}
<select multiple name="teacher_id">
{% for row in all_teacher_list %}
{% if row in class_teacher_list %}
<option value="{{ row.id }}" selected="selected">{{ row.TeacherName}}</option>
