1、新建一个mysite项目：django-admin startproject mysite 

2、进入项目目录，新建一个app ： python manage.py startapp polls

3、安装mysqlclient ：pip install mysqlclient

4、在settings.py  database中设置数据库连接配置

DATABASES = {
      'default': {
          'ENGINE': 'django.db.backends.mysql',         'NAME': 'my_web',         'USER': 'root',         'PASSWORD': 'password',         'HOST': '127.0.0.1',         'PORT': '3306',     } }

5、执行命令： python manage.py migrate

在数据库中自动创建web系统使用到的表

 

6、编辑polls/models.py文件内容

from django.db import modelsclass Question(models.Model):    question_text = models.CharField(max_length=200)    pub_date = models.DateTimeField('date published')class Choice(models.Model):    question = models.ForeignKey(Question, on_delete=models.CASCADE)    choice_text = models.CharField(max_length=200)    votes = models.IntegerField(default=0)

 

7、修改mysite/settings.py 文件INSTALLED_APPS 添加  'polls.apps.PollsConfig',

INSTALLED_APPS = [     'polls.apps.PollsConfig',     'django.contrib.admin',     'django.contrib.auth',     'django.contrib.contenttypes',     'django.contrib.sessions',     'django.contrib.messages',     'django.contrib.staticfiles', ]

7、执行命令：python manage.py makemigrations polls

Migrations for 'polls':  polls/migrations/0001_initial.py:    - Create model Choice    - Create model Question    - Add field question to choice 8、执行命令:python manage.py sqlmigrate polls 0001

 9 再执行python manage.py migrate 命令，创建数据库表
