1.扫描installed_apps，创建需要的数据库table

python manage.py migrate

2.在APP中创建模板（models）

from django.db import models


class 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)

3.安装一个app

# mysite/settings.py
INSTALLED_APPS = [
    ‘polls.apps.PollsConfig‘,
...

4.对于model做出的变化更新

python manage.py makemigrations polls

python manage.py migrate
