Django django-smart-select：管理サイトにデータを追加中にTemplateSyntaxErrorを取得します

Question

私はDjango初心者です。私はこのアプリを試してみたいdjango-smart-selects。私は、管理サイトの「注文」フォームで適切な「顧客」を選択することにより、「顧客」アドレスが自動入力されるようにしたいと思います。

だから私は、次の

models.py今

from smart_selects.db_fields import ChainedForeignKey 
from django.db import models 

# Adress model 
class Adresse (models.Model): 
    strasse = models.CharField(max_length=50) 
    plz = models.IntegerField(max_length=5) 
    ort = models.CharField(max_length=50) 

    def __unicode__(self): 
     return self.strasse 

# Customer model 
class Customer (models.Model): 
    name = models.CharField(max_length=50) 
    adresse = models.ForeignKey(Adresse) 

    def __unicode__(self): 
     return self.name 

# Order model 
class Order (models.Model): 
    name = models.CharField(max_length=50) 
    delivery_time = models.DateTimeField() 
    created_at = models.DateTimeField(auto_now_add=True) 
    kunde = models.ForeignKey(Customer, related_name="Kunde") 
    adresse = ChainedForeignKey(
         Customer, 
         chained_field="kunde", 
         chained_model_field="strasse", 
         show_all=False, 
         auto_choose=True 
        ) 

    class Meta: 
     db_table = 'order' 
     ordering = ['-created_at'] 

    def __unicode__(self): 
     return self.name 

admin.py

from django.contrib import admin 
from customer_order.test_app.models import Adresse, Customer, Order 

class AdresseAdmin(admin.ModelAdmin): 
    list_display = ('strasse', 'plz', 'ort',) 

class CustomerAdmin(admin.ModelAdmin): 
    list_display = ('name', 'adresse',) 
    list_per_page = 50 

class OrdersAdmin(admin.ModelAdmin): 
    list_display = ('name', 'delivery_time', 'created_at', 'kunde', 'adresse',) 
    list_display_links = ('name',) 
    list_per_page = 50 
    ordering = ['-created_at'] 

admin.site.register(Adresse, AdresseAdmin) 
admin.site.register(Customer, CustomerAdmin)  
admin.site.register(Order, OrdersAdmin) 

私が最初にエントリを追加したい定義されています管理者の追加ボタンを使用して "注文"テーブル、私は次のeを得たrror：
