Django图书管理系统

创建一个项目

1. django-admin startproject 图书管理
2. cmd 命令终端下创建一个app
    python manage.py startapp app01

配置settings.py文件（此处填写了后续需要配置的所有内容）

1、注释该行内容（大约在47~57行）
 #   ‘django.middleware.csrf.CsrfViewMiddleware‘,
2、连接数据库的配置（注释掉原来的 DATABASES）
DATABASES = {
‘default‘: {
    ‘ENGINE‘: ‘django.db.backends.mysql‘,
    ‘NAME‘: "book_m_s",
    ‘HOST‘: "127.0.0.1",
    ‘PORT‘: 3306,
    ‘USER‘: ‘root‘,
    ‘PASSWORD‘: ‘123456‘,
    }
}
3、静态文件的配置
STATIC_URL = ‘/static/‘
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, "static")
]
4、app添加
INSTALLED_APPS = [
    ‘django.contrib.admin‘,
    ‘django.contrib.auth‘,
    ‘django.contrib.contenttypes‘,
    ‘django.contrib.sessions‘,
    ‘django.contrib.messages‘,
    ‘django.contrib.staticfiles‘,
    ‘app01.apps.App01Config‘,
]

init.py文件，引入pymysql模块，使用mysql数据库

import pymysql
pymysql.install_as_MySQLdb()

app01/modles.py文件，创建数据表

from django.db import models
# Create your models here.
# 出版社表
class Publisher(models.Model):
    # 自增的ID主键
    id = models.AutoField(primary_key=True)
    # 创建一个varchar(64)的唯一的不为空的字段，且不能为空，且不重复
    name = models.CharField(max_length=64, null=False, unique=True)

# 书籍表
class Book(models.Model):
    # 自增的ID主键
    id = models.AutoField(primary_key=True)
    # 创建一个varchar(64)的唯一的不为空的字段，且不能为空，且不重复
    title = models.CharField(max_length=64, null=False, unique=True)
    # 告诉ORM我这张表和Publisher表是关联关系，ORM自动帮我创建关联ID （publisher_id）字段
    publisher = models.ForeignKey(to="Publisher")

# 作者表
class Author(models.Model):
    # 自增的ID主键
    id = models.AutoField(primary_key=True)
    # 创建一个varchar(64)的唯一的不为空的字段，且不能为空，且不重复
    name = models.CharField(max_length=16, null=False, unique=True)
    # 告诉ORM 我这张表和book表是多对多的关联关系，ORM自动帮我生成了第三张表
    book = models.ManyToManyField(to="Book")

urls.py文件，配置路由

from django.conf.urls import url
from django.contrib import admin
from app01 import views

urlpatterns = [
    url(r‘^admin/‘, admin.site.urls),
    # 出版社相关的对应关系
    # 出版社列表
    url(r‘^publisher_list/‘, views.publisher_list),
    # 添加出版社
    url(r‘^add_publisher/‘, views.add_publisher),
    # 删除出版社
    url(r‘^delete_publisher/‘, views.delete_publisher),
    # 编辑出版社
    url(r‘^edit_publisher/‘, views.edit_publisher),

    # 书籍相关的对应关系
    # 书籍列表
    url(r‘^book_list/‘, views.book_list),
    # 添加书籍
    url(r‘^add_book/‘, views.add_book),
    # 删除书籍
    url(r‘^delete_book/‘, views.delete_book),
    # 编辑书籍
    url(r‘^edit_book/‘, views.edit_book),

    # 作者相关的对应关系
    # 作者列表
    url(r‘^author_list/‘, views.author_list),
    # 添加作者
    url(r‘^add_author/‘, views.add_author),
    # 删除作者
    url(r‘^delete_author/‘, views.delete_author),
    # 编辑作者
    url(r‘^edit_author/‘, views.edit_author),
]

app01/views.py文件
