2.python----模型类

1. 在models.py中穿件BlogArticle

   from django.db import models
   from django.utils import timezone
   from django.contrib.auth.models import User
   
   
   # Create your models here.
   class BlogArticle(models.Model):
       title = models.CharField(max_length=300)
       author = models.ForeignKey(User, related_name="blogs_posts",on_delete=models.CASCADE)
       body = models.TextField()
       publish = models.DateTimeField(default=timezone.now())
   
       class Meta:
           ordering=("-publish",)
   
       def __str__(self):
           return  self.title

   命令行执行

   python manage.py makemigrations **迁移**
   
   python manage.py sqlmigrate blog 0001 **更新到数据库**
