Django admin
Django强大的功能之一就是提供了Admin后台管理界面，简单配置就可以对数据库内容做管理
创建ModelAdmin并注册
from django.contrib import admin from . import models # version 1 admin.site.register(models.Author) # version 2 class AuthorAdmin(admin.ModelAdmin): pass admin.site.register(models.Author, AuthorAdmin) # version 3 @admin.register(models.Author) class AuthorAdmin(admin.ModelAdmin): pass说明：
django启动时，会自动去app下寻找admin模块，生成后台页面自动根据model的Field类型设置Form类型
配置ModelAdmin
label名称，定义Model Field是指定verbose_name
排除某些字段 exclude
显示有些字段 fields
搜索某列 search_fields
添加日期标签过滤 date_hierarchy
排序 ordering
列表显示更多列 list_dispaly
# 当出现多个字段含义，list_display展示时 def display_book_authors(obj): return ','.join([author.first_name for author in obj.authors.all() ]) display_book_authors.short_description = 'Authors' # 展示列明 @admin.register(models.Book) class BookAdmin(admin.ModelAdmin): fields = ('title', 'authors', 'publisher') search_fields = ('title', 'authors') date_hierarchy = 'publication_date' ordering = ('-id', 'publication_date',) list_display = ['title', 'publisher', display_book_authors, 'publication_date']
配置Action
def make_book_pub_date_now(modeladmin, request,queryset): queryset.update(publication_date=datetime.datetime.now()) @admin.register(models.Book) class BookAdmin(admin.ModelAdmin): list_display = ['title', 'publisher', 'publication_date'] actions = [make_book_pub_date_now]
