实现功能：book单表的增删改查
代码：
model.py
from django.db import models # Create your models here. class Book(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=32) pub_date = models.DateField() price = models.DecimalField(max_digits=8, decimal_places=2) publish = models.CharField(max_length=32)
settings.py
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'bookms', # 要连接的数据库，连接前需要创建好 'USER': 'root', # 连接数据库的用户名 'PASSWORD': '123', # 连接数据库的密码 'HOST': '127.0.0.1', # 连接主机，默认本机 'PORT': 3306 # 端口 默认3306 } } # 打印orm转换过程中的sql LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console':{ 'level':'DEBUG', 'class':'logging.StreamHandler', }, }, 'loggers': { 'django.db.backends': { 'handlers': ['console'], 'propagate': True, 'level':'DEBUG', }, } }
