Django之图书管理系统

一、创建项目文件夹
选择位置创建文件夹，在cmd中输入以下命令创建项目

django-admin startproject bookproject
1

点击创建的文件夹后再次cmd输入：

python manage.py startapp app01
1

在这里插入图片描述

二、打开python软件，配置
1、settings（其他配置跟以往相同）只需添加以下代码

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': "bookshop",#数据名
        "USER":"root",#用户名
        "PASSWORD":"root",
        "HOST":"",#域名
        "PORT":"3306",#端口号
    }
}

注：配置完成后手动添加文件夹static和template

2.配置models

#创建出版社对象
class Publisher(models.Model):
    id = models.AutoField(primary_key = True)
    name = models.CharField(max_length=64,null=False)
    address = models.CharField(max_length=64,null=False)

#创建图书
class Book(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=32)
    price = models.DecimalField(max_digits=5,decimal_places=2,default=10.01)
    inventory = models.IntegerField(verbose_name='库存数')
    sale_num = models.IntegerField(verbose_name='卖出数')
    publisher = models.ForeignKey(to='Publisher', on_delete=models.CASCADE)

#创建作者列表
class Author(models.Model):

    name = models.CharField(max_length=32)
    book = models.ManyToManyField(to='Book')

三、迁移数据库并写入数据库，启动项目

python manage.py makemigrations

python manage.py migrate

python manage.py runserver

四、创建路由

from django.contrib import admin
from django.urls import path
from app01 import views
urlpatterns = [
    #path('admin/', admin.site.urls),
    #添加出版社路由
    path('add_publisher/',views.add_publisher),
    # 出版社路由列表
    path('publisher_list/',views.publisher_list),
    # 修改出版社路由
    path('edit_publisher/',views.edit_publisher),
    # 图书列表路由
    path('book_list/',views.book_list),
    # 添加图书路由
    path('add_book/',views.add_book),
    # 修改路由
    path('edit_book/',views.edit_book),
    # 删除图书路由
    path('delete_book/',views.delete_book),
    # 删除出版社路由
    path('delete_publisher/',views.delete_publisher),
    # 作者列表路由
    path('author_list/',views.author_list),
    # 添加作者路由
    path('add_author/',views.add_author),
    # 修改作者路由
    path('edit_author/',views.edit_author),
    # 删除作者路由
    path('delete_author/',views.delete_author),
]

五、新建HTML页

六、写入views视图代码
首先导入redirect和models 模块
1.出版社

from django.shortcuts import render, redirect
from app01 import models


# Create your views here.

#添加出版社
def add_publisher(request):
    if request.method == "POST":
        # 获取表单提交的内容
        publisher_name = request.POST.get('name')
        publisher_address = request.POST.get('address')
        # 保存数据库表单中
        models.Publisher.objects.create(name=publisher_name, address=publisher_address).save()
        return redirect('/app01/publisher_list/')
    return render(request, 'add_publisher.html')




# 删除出版社
def delete_publisher(request):
    # 获取删除图书的ID
    id = request.GET.get('id')
    # 根据ID删除数据库中的记录
    models.Publisher.objects.filter(id=id).delete()
    return redirect('/app01/publisher_list/')

        name = request.POST.get('name')
        address = request.POST.get('address')
        # 根据ID去数据库中查找对象
        publisher_obj = models.Publisher.objects.get(id=id)
        # 修改
        publisher_obj.name = name
        publisher_obj.address = address
        publisher_obj.save()
        return redirect('/app01/publisher_list/')
    else:
        # 获取ID

        # 去数据库中查找相应的数据
        publisher_obj = models.Publisher.objects.get(id=id)
        publisher_obj_list = models.Publisher.objects.all()
        # 3返回页面
        return render(request, 'edit_publisher.html',
                      {"publisher_obj": publisher_obj, "publisher_obj_list": publisher_obj_list})

# 图书列表
def book_list(request):

    book_obj_list = models.Book.objects.all()
    print(book_obj_list)

七、编写HTML页面
首先写入母板，其他网页都调用其母板
（母板）

<!DOCTYPE html>
<html lang="zh-CN">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <!-- 上述3个meta标签*必须*放在最前面，任何其他内容都*必须*跟随其后！ -->
    <title>图书管理系统</title>

    <!-- Bootstrap -->
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css" rel="stylesheet">

    <!-- HTML5 shim 和 Respond.js 是为了让 IE8 支持 HTML5 元素和媒体查询（media queries）功能 -->
    <!-- 警告：通过 file:// 协议（就是直接将 html 页面拖拽到浏览器中）访问页面时 Respond.js 不起作用 -->
    <!--[if lt IE 9]>
     <script src="https://cdn.jsdelivr.net/npm/html5shiv@3.7.3/dist/html5shiv.min.js"></script>
      <script src="https://cdn.jsdelivr.net/npm/respond.js@1.4.2/dest/respond.min.js"></script>
    <![endif]-->
