创建模型并渲染页面
创建模型文件
- 创建文件：
blog/model/article.py - 写入：
from __future__ import unicode_literals
from django.db import models
# Create your models here.
class Article(models.Model):
title = models.CharField(max_length=255, null=True)
content = models.TextField(max_length=0, null=True)
修改模型文件：blog/models.py
from __future__ import unicode_literals
from django.db import models
# Create your models here.
from model import article
