Я новичок в Джанго.Я хочу попробовать это приложение django-smart-selects .Мне бы хотелось, чтобы адрес «Заказчик» автоматически заполнялся путем выбора подходящего «Заказчика» в форме «Заказ» на сайте администратора.
Итак, я определил следующее
models.py
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)
Теперь, когда я хочу добавить первые записи в «Заказ»«Таблица через админ-кнопку добавления, я получил следующую ошибку:
Request Method: GET
