项目使用python开发，采用Django框架，数据库采用MySQL，根据用户人员的不同分成两套系统，分别是学生系统和管理员系统，功能模块具体分成四个，分别是用户管理模块、图书管理模块、数据管理模块、前端模块。
1、用户管理模块
用户管理模块实现的功能包括用户注册（分为学生注册和管理员注册）、用户信息修改、用户登录和判定
用户注册和登录
views.py中用户注册及登陆判定代码段
def login(request):#登录
return render(request, 'login.html')
def student_register(request): # 学生注册
name = request.POST.get("student_name") # 获取学生输入的姓名
id = request.POST.get("student_id") # 获取学生输入的学号
major = request.POST.get("student_major") # 获取学生输入的学院
email = request.POST.get("student_email") # 获取学生输入的邮箱
telephone = request.POST.get("student_telephone")
password = request.POST.get("student_password")
result1 = User.objects.filter(account=telephone) # 在用户表中搜索该用户名的记录
result2 = Student.objects.filter(student_id=id) # 在学生表中搜索该学号的记录
context = {}
if len(result1) == 1: # 判断该账户是否存在(即判断是否注册过)，如果后台存在记录，则返回相应的提示语句
context["info"] = "该账户已注册！！！"
context["status"] = 0 #零表示注册失败
return render(request, 'login.html', context=context)
else: #该账户是新用户

else:

context["info"] = "注册成功！"
context["status"] = 1 #1表示注册成功

telephone = request.POST.get("manager_telephone")
password = request.POST.get("manager_password")

context["info"] = "注册成功！"
context["status"] = 1 #1表示注册成功
return render(request, 'login.html', context=context)
def login_judge(request):#登入判定
global account ,global_sname,global_mname #定义全局变量account,存储该用户的账户，global_sname保存一下该学生的姓名,global_mname保存一下该学生的姓名

图书馆里模块实现的功能与我们日常图书馆的借阅系统相似，学生端包括书籍查询、书籍借阅、书记归还；管理员端包括书籍采购、书籍信息修改等更多扩展功能
书籍查询及借阅归还，可选择按书籍名或类型查找

else:
return render(request, 'manager/add_new_book.html', context={ "name": global_mname,"types":types})3、数据管理模块
数据管理模块主要是设计数据库的存储和操作，django的ROM机制可以让用户在models上面编写要创建的数据表类型，通过执行迁移，直接在数据库创建数据库表
models.py代码段
from django.db import models
class User(models.Model): #用户表
account=models.CharField(max_length = 20,primary_key=True)#账号
user_password=models.CharField(max_length = 20)#用户密码
user_identity=models.CharField(max_length = 20)#用户身份
class Student(models.Model): #学生信息表
student_id=models.CharField(max_length = 20,primary_key=True)#学号 主键
student_name=models.CharField(max_length=20)#姓名
student_tel=models.CharField(max_length = 20)#电话
student_major=models.CharField(max_length = 20)#院系
student_email=models.CharField(max_length = 50)#邮箱
class Manager(models.Model): #图书管理员信息表
manager_id=models.CharField(max_length = 20,primary_key=True)#工号 主键
manager_name=models.CharField(max_length=20)#姓名
manager_tel=models.CharField(max_length = 20)#电话
manager_email=models.CharField(max_length = 50)#邮箱
manager_stack=models.CharField(max_length = 20)#管理书库
class Type(models.Model):#书籍类型表
type_id= models.CharField(max_length=20,primary_key=True) # 类型编号，主键
type_name = models.CharField(max_length=20) # 类型名称
class Book(models.Model):#书本信息表
ISBN= models.CharField(max_length = 20,primary_key=True) # 国际标准书号 主键
book_name = models.CharField(max_length=20) # 书名
book_author = models.CharField(max_length=20) # 作者
book_publisher = models.CharField(max_length=20) # 出版社
book_version = models.CharField(max_length=20) # 版本
book_price = models.CharField(max_length=20) # 价格
book_number = models.IntegerField() # 总库存数(馆藏数）
book_rest = models.IntegerField() # 可借数
book_place = models.CharField(max_length=20) # 所属书库
book_type = models.ForeignKey(Type, on_delete=models.CASCADE)#书籍类型
class Borrow(models.Model):#借阅表
student_id= models.CharField(max_length=20) # 借书人学号
student_name = models.CharField(max_length=20) # 借书人姓名
student_tel = models.CharField(max_length=20) # 借书人联系方式
book_id = models.CharField(max_length=20) # 书籍编号
book_name = models.CharField(max_length=20) # 书名
borrow_time = models.CharField(max_length=20) # 借书时间
rest_time = models.IntegerField() # 剩余天数settings.py关于数据库的相关设定
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'Library', #数据库名字
'USER': 'xxxx', #用户名
'PASSWORD': 'xxxx',#密码
'HOST': 'localhost', #本地主机
'PORT': '3306' #端口号
}
}4、前端模块
前端模块是向用户展示的用户界面，通常保存在templates文件夹下，后端通过与前端的数据进行交互，通过路由返回具体的页面实现渲染。
templates文件夹目录
urls.py路由路径
from django.contrib import admin
from django.urls import path,include
from MyApp import views as App_views
urlpatterns = [
path('admin/', admin.site.urls),
path('MyApp/',include('MyApp.urls')),
path('login/',App_views.login),
path('student_register/',App_views.student_register),
