django博客开发目录
- 一、项目准备
- 二、设计表结构
- 三、创建项目
-
- 1. 创建django的基础环境
- 2. 配置博客项目
- 3. 实现基于用户认证组件和Ajax实现登录验证(图片验证码)
一、项目准备
项目中,需求驱动开发。即开发人员需要以需求为目标来实现业务逻辑。
1 需求分析(产品经理)
- 基于用户认证组件和Ajax实现登录验证(图片验证码)
- 基于forms组件和Ajax实现注册功能
- 设计系统首页(文章列表渲染)
- 设计个人站点页面
- 文章详情页
- 实现文章点赞功能
- 实现文章的评论
---文章的评论
---评论的评论 - 富文本编辑框和防止xss攻击
2 设计表结构
3 按着每一个功能分别进行开发
4 功能测试
5 项目部署上线
二、设计表结构
在Django中,表结构是通过模型(models)来设计的,而不是直接操作数据库表。Django的ORM(对象关系映射)允许你使用Python代码定义数据模型,然后由Django来处理与数据库的交互。
from django.db import models #Create your models here. from django.contrib.auth.models import AbstractUser class UserInfo(AbstractUser): """ 用户信息 """ nid = models.AutoField(primary_key=True) telephone = models.CharField(max_length=11, null=True, unique=True) avatar = models.FileField(upload_to='avatars/', default="/avatars/default.png") create_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True) blog = models.OneToOneField(to='Blog', to_field='nid', null=True, on_delete=models.CASCADE) def __str__(self): return self.username class Blog(models.Model): """ 博客信息 """ nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='个人博客标题', max_length=64) site_name = models.CharField(verbose_name='站点名称', max_length=64) theme = models.CharField(verbose_name='博客主题', max_length=32) def __str__(self): return self.title class Category(models.Model): """ 博主个人文章分类表 """ nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='分类标题', max_length=32) blog = models.ForeignKey(verbose_name='所属博客', to='Blog', to_field='nid', on_delete=models.CASCADE) def __str__(self): return self.title class Tag(models.Model): nid = models.AutoField(primary_key=True) title = models.CharField(verbose_name='标签名称', max_length=32) blog = models.ForeignKey(verbose_name='所属博客', to='Blog', to_field='nid', on_delete=models.CASCADE) def __str__(self): return self.title class Article(models.Model): nid = models.AutoField(primary_key=True) title = models.CharField(max_length=50, verbose_name='文章标题') desc = models.CharField(max_length=255, verbose_name='文章描述') create_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True) content = models.TextField() comment_count = models.IntegerField(default=0) up_count = models.IntegerField(default=0) down_count = models.IntegerField(default=0) user = models.ForeignKey(verbose_name='作者', to='UserInfo', to_field='nid', on_delete=models.CASCADE) category = models.ForeignKey(to='Category', to_field='nid', null=True, on_delete=models.CASCADE) tags = models.ManyToManyField( to="Tag", through='Article2Tag', through_fields=('article', 'tag'), ) def __str__(self): return self.title class Article2Tag(models.Model): nid = models.AutoField(primary_key=True) article = models.ForeignKey(verbose_name='文章', to="Article", to_field='nid', on_delete=models.CASCADE) tag = models.ForeignKey(verbose_name='标签', to="Tag", to_field='nid', on_delete=models.CASCADE) class Meta: unique_together = [ ('article', 'tag'), ] def __str__(self): v = self.article.title + "---" + self.tag.title return v class ArticleUpDown(models.Model): """ 点赞表 """ nid = models.AutoField(primary_key=True) user = models.ForeignKey('UserInfo', null=True, on_delete=models.CASCADE) article = models.ForeignKey("Article", null=True, on_delete=models.CASCADE) is_up = models.BooleanField(default=True) class Meta: unique_together = [ ('article', 'user'), ] class Comment(models.Model): """ 评论表 """ nid = models.AutoField(primary_key=True) article = models.ForeignKey(verbose_name='评论文章', to='Article', to_field='nid', on_delete=models.CASCADE) user = models.ForeignKey(verbose_name='评论者', to='UserInfo', to_field='nid', on_delete=models.CASCADE) content = models.CharField(verbose_name='评论内容', max_length=255) create_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True) parent_comment = models.ForeignKey('self', null=True, on_delete=models.CASCADE) def __str__(self): return self.content
