Django-Admin.py不顯示模型

Question

「給出的管理聲明中的每個對象是否顯示出主索引頁的」 這條線是指這樣的事實，簡單

class Admin: pass 

聲明在Django模型自動生成Django管理員主頁的更改和添加接口...此功能仍可用嗎？我的Urls .py是正確的，我已將我的應用程序添加到已安裝的應用程序，並且我的數據庫設置是正確的，但我沒有看到我的管理頁面上的對象。它令人沮喪，因爲沒有錯誤拋出。我已經多次運行syncdb ..甚至通過向我的數據庫添加新字段和新對象來測試sync db，但仍然沒有改變。 幫助。請。 這裏是我設置的.py，models.py中URLs.py

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) 
    websites=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=30) 
    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=100) 
    authors=models.ManyToManyField(Author) 
    publisher=models.ForeignKey(Publisher) 
    publication_date=models.DateField() 
    no_of_books_produced=models.CharField(max_length=100)

除非事情已經從根本上改變了最近你還需要一個admin.py用於定義管理類的地方，然後註冊它。你嘗試過嗎？
