python3 django学习

1、django-admin startproject mysite

2、进到mysite目录 python manage runserver

使用 http://172.0.0.1:8000/ 登录

3、创建应用 python manage startapp blog

4、在models.py 写数据模型

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
class BlogArticles(models.Model):
　　title = models.CharField(max_length=300)
　　author = models.ForeignKey(User,related_name=‘blog_posts‘,on_delete = models.CASCADE,)
　　body = models.TextField()
　　publish = models.DateTimeField(default=timezone.now)

　　class Meta:
　　　　ordering = (‘-publish‘,)
　　def __str__(self):
　　　　return self.title

开始报TypeError: __init__() missing 1 required positional argument: ‘on_delete‘错误，查询解决https://www.cnblogs.com/phyger/p/8035253.html
