设计思路

　

1.产品需求

　　(1) 基于用户认证组件和Ajax实现登录验证(图片验证码)

　　(2) 基于forms组件和Ajax实现注册功能

　　(3) 设计系统首页 (文章列表渲染)

　　(4) 设计个人站点页面

　　(5) 文章详情页

　　(6) 实现文章点赞功能

　　(7) 实现文章的评论
　　　　------文章的评论
　　　　------评论的评论

　　(8) 富文本编辑框和防止xss攻击

2.设计表结构

　　表关系如下：

　　

根据表关系创建出如下8个表

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.jpg")
    creat_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):
    """
    博客信息表(站点表)
    """
    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
    """
    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):
    """
    标签表
    """
    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):
    """
    文章表
    """
    nid = models.AutoField(primary_key=True)
    title = models.CharField(verbose_name="文章标题", max_length=50)
    desc = models.CharField(verbose_name="文章描述", max_length=255)
    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(verbose_name="分类", 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):
    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)
    user = models.ForeignKey(verbose_name="评论者", to="UserInfo", to_field="nid", on_delete=models.CASCADE)
    article = models.ForeignKey(verbose_name="评论文章", to="Article", to_field="nid", on_delete=models.CASCADE)
    create_time = models.DateTimeField(verbose_name="评论时间", auto_now_add=True)
    content = models.CharField(verbose_name="评论内容", max_length=255)
    parent_comment = models.ForeignKey("self", null=True, on_delete=models.CASCADE)

    def __str__(self):
        return self.content
