django administration 小记

一、在modlues模块中添加如下代码

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
# Create your models here.


class BlogArticles(models.Model):
    title = models.CharField(max_length=300)
    author = models.ForeignKey(User, related_name="blog_posts")
    body = models.TextField()
    publish = models.DateTimeField(default=timezone.now)

    class Meta:
        ordering = ("-publish",)

    def __str__(self):
        return self.title

　　

使用命令python manage.py makemigrations 

　　　　python manage.py migrate3

　　　　python manage.py createsuperuser　　# 创建超级管理员用户

二、在admin模块中添加如下代码

from django.contrib import admin
from .models import BlogArticles
# Register your models here.


class BlogArticlesAdmin(admin.ModelAdmin):
    list_display = ("title", "author", "publish")  # 在描述中显示对应的数据库字段
    list_filter = ("publish", "author",)           # 在右方添加标签页，可以已数据库字段分类
    search_fields = ('title', "body")              # 搜索功能()中添加要搜索的字段
    raw_id_fields = ("author",)
    date_hierarchy = "publish"
    ordering= ['publish', 'author']                # 给list_filter添加排序功能


admin.site.register(BlogArticles, BlogArticlesAdmin)
