python之为什么没有出现 Django 管理界面_编程设计

我是 django 的新手。

我正在尝试根据一本关于 Django 的书来运行示例。

我已经在我的模型类中添加了“class Admin”，但是，在 django 管理界面中，我只能看到“Users”、“Groups”和“Sites”，我的模型类都没有出现。

没有错误和警告信息，所以我不知道发生了什么，接下来该怎么办。

有什么帮助吗？

from django.db import models 
 
# Create your models here. 
class Publisher(models.Model): 
    name = models.CharField(max_length=30) 
    address=models.CharField(max_length=50) 
    city=models.CharField(max_length=60) 
    state_province=models.CharField(max_length=30) 
    country=models.CharField(max_length=50) 
    website=models.URLField() 
 
    def __str__(self): 
        return self.name 
 
    class Admin: 
        pass 
 
class Author(models.Model): 
    salutation=models.CharField(max_length=10) 
    first_name = models.CharField(max_length=30) 
    last_name = models.CharField(max_length=40) 
    email=models.EmailField() 
    headshot=models.ImageField(upload_to='/tmp') 
 
    def __str__(self): 
        return '%s %s' % (self.first_name, self.last_name) 
 
    class Admin: 
        pass 
 
class Book(models.Model): 
    title=models.CharField(max_length=10) 
    authors=models.ManyToManyField(Author) 
    publisher=models.ForeignKey(Publisher) 
    publication_date = models.DateField() 
 
    def __str__(self): 
        return self.title

请您参考如下方法:

您需要做三件事才能通过管理站点编辑您的模型:

使用代码在您的应用程序目录中创建文件“admin.py”(查看 https://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-objects):

from django.contrib import admin 
from your_app.models import Publisher, Author, Book 
 
admin.site.register(Author) 
admin.site.register(Publisher) 
admin.site.register(Book)

在您的 urls.py 中添加以下内容(查看 https://docs.djangoproject.com/en/dev/ref/contrib/admin/#hooking-adminsite-instances-into-your-urlconf ):

from django.conf.urls import patterns, url, include 
from django.contrib import admin 
 
admin.autodiscover() 
 
urlpatterns = patterns('', 
    (r'^admin/', include(admin.site.urls)), 
    # your urls goes here 
)

确保您的 settings.py 满足以下要求(查看 https://docs.djangoproject.com/en/dev/ref/contrib/admin/#overview ):

TEMPLATE_CONTEXT_PROCESSORS = ( 
    'django.contrib.messages.context_processors.messages', 
    #other context processors 
) 
 
MIDDLEWARE_CLASSES = ( 
    'django.contrib.messages.middleware.MessageMiddleware', 
    # other middleware 
) 
 
INSTALLED_APPS = ( 
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.messages', 
    'django.contrib.sessions', 
    # other apps 
)
