Django2 数据模型定制后台管理

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
