新建项目，并开启
python manage.py runserver 8080访问admin页面
http://127.0.0.1:8080/admin补充：若是发现admin页面样式丢失：可能是因为在settings文件中的数据格式写错了，比如：
STATICFILES_DIRS 是元组类型，若是在os.path.join(BASE_DIR,'static')后面忘记加上逗号分隔符，则可能会丢失样式，无法找到 STATICFILES_DIRS = ( os.path.join(BASE_DIR,'static'), )此时并没有账号和密码：需要先配置数据库，在生成用户
配置数据库 python manage.py makemigrations python manage.py migrate 创建用户 python manage.py createsuperuser 需要填写用户名，邮箱，密码管理Django数据库的APP--->phpmyadmin,web版管理数据库
创建数据表：
# -*- coding: utf-8 -*- from __future__ import unicode_literals from django.db import models # Create your models here. class Publisher(models.Model): name = models.CharField(max_length=30, verbose_name="名称") address = models.CharField("地址", max_length=50) city = models.CharField('城市', max_length=60) state_province = models.CharField(max_length=30) country = models.CharField(max_length=50) website = models.URLField() class Meta: verbose_name = '出版商' verbose_name_plural = verbose_name def __str__(self): return self.name class Author(models.Model): name = models.CharField(max_length=30) def __str__(self): return self.name class AuthorDetail(models.Model): sex = models.BooleanField(max_length=1, choices=((0, '男'), (1, '女'),)) email = models.EmailField() address = models.CharField(max_length=50) birthday = models.DateField() author = models.OneToOneField(Author) class Book(models.Model): title = models.CharField(max_length=100) authors = models.ManyToManyField(Author) publisher = models.ForeignKey(Publisher) publication_date = models.DateField() price = models.DecimalField(max_digits=5, decimal_places=2, default=10) def __str__(self): return self.title models.py python manage.py makemigrations python manage.py migrate 配置数据库在admin.py中配置数据库进行管理
from __future__ import unicode_literals from django.contrib import admin from app01.models import * # Register your models here. admin.site.register(Book) admin.site.register(Publisher) #会显示设置的verbose_name 在Admin中字段的显示名称 admin.site.register(Author) python manage.py runserver 8080 启动项目再次访问
在web页面进行添加：
若是有中文则会出错，解决方法请看：python---补充django中文报错
若是想将页面设置为中文显示，可以设置settings文件：
#LANGUAGE_CODE = 'en-us' LANGUAGE_CODE = 'zh-hans'由于在建立orm对象时，__str__中只返回了title，所以页面显示只有书籍名称，其他信息并不全
class Book(models.Model): title = models.CharField(max_length=100) authors = models.ManyToManyField(Author) publisher = models.ForeignKey(Publisher) publication_date = models.DateField() price = models.DecimalField(max_digits=5, decimal_places=2, default=10) def __str__(self): #__str__需要返回字符串 return self.title
当没有__str__时，只会显示出
要想显示更多信息，需要我们在admin.py模块中自定义类，来设置显示的字段
class MyAdmin(admin.ModelAdmin): list_display = ("title","price","publisher") #设置显示的字段，与原来__str__无关了 admin.site.register(Book,MyAdmin) #使MyAdmin与Book产生联系 admin.site.register(Publisher) admin.site.register(Author)可以修改models中的字段，设置别名在admin中显示
class Book(models.Model): title = models.CharField(max_length=100,verbose_name="书名")
搜索框：
class MyAdmin(admin.ModelAdmin): list_display = ("title","price","publisher") #设置显示的字段，与原来__str__无关了 search_fields = ("title","price",) #会生成搜索框，元组中是允许搜索的字段过滤器：
class MyAdmin(admin.ModelAdmin): list_display = ("title","price","publisher") #设置显示的字段，与原来__str__无关了 search_fields = ("title","price",) #会生成搜索框，元组中是允许搜索的字段 list_filter = ("price","publisher") #生成过滤器，以price过滤
排序：
class MyAdmin(admin.ModelAdmin): list_display = ("title","price","publisher") #设置显示的字段，与原来__str__无关了 search_fields = ("title","price",) #会生成搜索框，元组中是允许搜索的字段 list_filter = ("price","publisher") #过滤器 ordering = ("-price",) #排序，默认id排序，升序，降序，则使用在字段前使用 '-' readonly_fields = [] #设置不允许修改
显示和隐藏：在添加和修改时使用：
fieldsets = [ (None, {'fields': ['title']}), #None代表其他字段隐藏，fields中字段显示 ] fieldsets = [ (None, {'fields': ['title']}), ('price information', {'fields': ['price', "publisher"], }), #组名为price information] fieldsets = [ (None, {'fields': ['title']}), ('price information', {'fields': ['price', "publisher"], 'classes': ['collapse']}), #classes样式折叠 ]
