五、开发后台管理（一）

五、开发后台管理（一）

第四节中迁移了数据库并且创建了后台管理员，登录后台发现三个应用还没有注册进入后台，这一节记录了后台开发，到后面我们会使用xadmin来替换比较简陋的admin后台

先编辑blog/admin.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.contrib import admin

from .models import Post, Category, Tag


@admin.register(Post)
class PostAdmin(admin.ModelAdmin):
    list_display = [
        "title",
        "status",
        "category",
        "author",
        "created_time",
    ]
    list_filter = (
        "author",
    )
    date_hierarchy = "created_time"
    # 编辑页面
    fields = (
        ("title", 'category'),
        "tag",
        "author",
        "desc",
        "status",
        "content",
    )


@admin.register(Category)
class CategoryAdmin(admin.ModelAdmin):
    list_display = [
        "name",
        "status",
        "is_nav",
        "author",
        "created_time",
    ]
    fields = (
        "name",
        "status",
        "is_nav",
        "author",
    )


@admin.register(Tag)
class TagAdmin(admin.ModelAdmin):
    list_display = [
        "name",
        "status",
        "author",
        "created_time",
    ]
    fields = (
        "name",
        "status",
        "author",
    )

进入后台，我们先新增一篇文章，可以看到标签和分类是object，这里需要在models.py中增加定制类

class Tag(models.Model):
    ............
    
    def __unicode__(self):
        return self.name

class Category(models.Model):
    ................
    def __unicode__(self):
        return self.name

class Post(models.Model):
    .................


    def __unicode__(self):
        return self.name

config和comment应用也是这样开发后台，具体代码可以去github查看
