第一步：编辑应用的admin.py 文件，编辑内容如下：

from django.contrib import admin
    from blog.models import *  # 导入所有模型类
    
    
    @admin.register(Article) #Article 模型注册至后台
    class ArticleAdmin(admin.ModelAdmin):
        list_display = ('title', 'category', 'pub_time')  # Article 数据模型显示字段
    
    
    admin.site.register((Category, Comment, Tag))  # 多个模块注册到后台

第二步：编辑应用的models.py文件，编辑内容如下：

from django.db import models
    from django.contrib.auth.models import User  # 使用Django自带的用户模型
    from ckeditor.fields import RichTextField
    
    
    class Category(models.Model):  # 文章类别
        id = models.IntegerField(primary_key=True)
        name = models.CharField('类别', max_length=20, unique=True)
    
        class Meta:
            verbose_name_plural = verbose_name = '类别'
    
        def __str__(self):
            return self.name
    
    
    class Tag(models.Model):  # 文章标签
        name = models.CharField('标签', max_length=20, unique=True)
    
        class Meta:
            verbose_name_plural = verbose_name = '标签'
    
        def __str__(self):
            return self.name
    
    
    # 文章类
    class Article(models.Model):  # 文章
        id = models.AutoField(primary_key=True)
        author = models.ForeignKey(User, on_delete=models.DO_NOTHING, verbose_name='作者')
        title = models.CharField('标题', max_length=50)
        content = RichTextField('内容',config_name='mycfg')
        pub_time = models.DateField('日期', auto_now=True)
        category = models.ForeignKey(Category, on_delete=models.SET_DEFAULT, default=1, verbose_name='类别')
        tag = models.ManyToManyField(Tag, verbose_name='标签')
    
        class Meta:
            verbose_name_plural = verbose_name = '文章'
    
        def __str__(self):
            return self.title
    
    
    class Comment(models.Model): #评论
        id = models.AutoField(primary_key=True)
        name = models.CharField('昵称', max_length=20)
        email = models.EmailField('邮箱')
        content = models.TextField('内容')
        publish = models.DateField('时间', auto_now=True)
        article = models.ForeignKey(Article, on_delete=models.CASCADE, verbose_name='文章')
        reply = models.ForeignKey('self', on_delete=models.DO_NOTHING, null=True, blank=True, verbose_name='回复')
    
        class Meta:
            verbose_name_plural = verbose_name = '评论'
    
        def __str__(self):
            return self.content

第三步：后台效果展示：
