Python——Django框架——Model数据库模型

1、设置

一、Django的setting中配置数据库(MySQL配置)

DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': '数据库名称', 'USER': '数据库用户名', 'PASSWORD': '数据库密码', 'HOST': '主机地址', 'POST': '端口号', } } INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', '你的应用名称', ]

二、应用所在的__init__.py添加

import pymysql pymysql.install_as_MySQLdb()

三、修改Django包

3.1报错：django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.3 or newer is required; you have 0.7.11.None

解决方法：C:\Users\adong\AppData\Local\Programs\Python\Python36\Lib\site-packages\Django-2.0.3-py3.6.egg\django\db\backends\mysql\base.py

注释掉：

 

if version < (1, 3, 3): raise ImproperlyConfigured("mysqlclient 1.3.3 or newer is required; you have %s" % Database.__version__)

 

3.2修改：C:\Users\adong\AppData\Local\Programs\Python\Python36\Lib\site-packages\Django-2.0.3-py3.6.egg\django\db\backends\mysql\operations.py

 

 query = query.encode(errors='replace') 

 

2、建立Model模型（models.py）

from django.db import models class user(models.Model):#建立一个表
    id = models.AutoField(primary_key=True)#自增加id
    user = models.CharField(max_length=20) password = models.CharField(max_length=20) email = models.EmailField() phone = models.IntegerField() perorg = models.IntegerField()

3、生成数据库表

python manage.py makemigrations 应用名 python manage.py migrate

4、pycharm链接Mysql

4.1错误：【8001】Could not create connection to database server. Attempted reconnect 3 times. Giving up.

解决方法：将URL改为这个：jdbc:mysql://localhost:3306/【表名】?useSSL=false&serverTimezone=UTC
