数据库表的创建
两张表：
文章类型 文章
#一篇博客一种分类 # 一篇博客多种分类 from django.db import models from django.contrib.auth.models import User # Create your models here. class BlogType(models.Model): type_name=models.CharField(max_length=15,verbose_name="博客类型") def __str__(self): return self.type_name class Blog(models.Model): #博客标题 title=models.CharField(max_length=50,verbose_name="文章标题") #博客类型 blog_type=models.ForeignKey(BlogType,on_delete=models.DO_NOTHING,verbose_name="博客类型") #博客作者 author=models.ForeignKey(User,on_delete=models.DO_NOTHING,verbose_name="作者") #博客内容 content=models.TextField() #创建文章的时间 created_time=models.DateTimeField(auto_now_add=True,verbose_name="发表时间") #最后修改的时间 last_updated_time=models.DateTimeField(auto_now=True,verbose_name="最后修改时间") def __str__(self): return self.title

首页视图函数
from django.shortcuts import render,HttpResponse,redirect from blog.models import * #首页 def get_index(request): all_Type=BlogType.objects.all().values('type_name') return render(request,"index.html",{'all_Type':all_Type})
