Question

如何顯示，如果我加Apartament和Land對象還Contact表和Photo形式？

class Property(models.Model): 
    title = models.CharField(max_length=255) 
    slug = models.SlugField() 
    desc = models.TextField() 

class Apartament(Property): 
    bedrooms = models.IntegerField() 
    levels = models.IntegerField() 
    something = models.CharField(max_length=255) 

class Land(Property): 
    something = models.CharField(max_length=255) 

class Contact(models.Model): 
    name = models.CharField(max_length=100) 
    phone = models.CharField(max_length=20) 
    property = models.ForeignKey(Property) 

class Photo(models.Model): 
    photo = models.ImageField(upload_to='images') 
    property = models.ForeignKey(Property) 

admin.py：

class PhotoInline(admin.StackedInline): 
    model = Photo 
    can_delete = True 

class ContactInline(admin.StackedInline): 
    model = Contact 
    can_delete = True 

class PropertyAdmin(admin.ModelAdmin): 
    inlines = [PhotoInline, ContactInline, ] 

只有當我添加屬性對象這項工作。

管理員（內聯）不是對稱的，您需要爲這些模型註冊管理員類，包括您需要的內聯。
