添加在Django管理筛选器

Question

我有以下的模型 -

class NetworkAdministrator (models.Model): 
    email = models.EmailField() 
    admin_name = models.CharField(max_length=100, blank=True) 

class Network(models.Model): 
    network = models.CharField(max_length=50) 
    network_name = models.CharField(max_length=50) 
    administrators = models.ManyToManyField(NetworkAdministrator) 

在管理控制台中，任何网络添加，它显示所有管理员，就好像它是做什么 - NetworkAdministrator.objects.all()。

我将如何使它所以对于每个特定的网络中，组管理员只包括那些从目前的网络 -

Network.objects.get(network='**network name**').administrators.all()

从功能上说，这是我希望能够到在管理面板中执行：

1) add network = 'China' 
2) add 2 administrators to this network = cadmin1, cadmin2, cadmin3 
3) add network = 'India' 
4) add 2 administrators to this network: iadmin1, iadmin2 
    (no administrators should show from the China network). 

谢谢。

使用InlineModelAdmin

class AdministrationInline(admin.TabularInline): 
    model = Network.administrators.through 

class NetworkAdministratorAdmin(admin.TabularInline): 
    inlines = [ 
     AdministrationInline, 
    ] 

class NetworkAdmin(admin.ModelAdmin): 
    inlines = [ 
     AdministrationInline, 
    ] 
    exclude = ('administrators',) 

admin.site.register(Network, NetworkAdmin) 
admin.site.register(NetworkAdministrator, NetworkAdministratorAdmin) 

请注意：through中介模式和'administrators'
