django 1.3.1 ve satchmo 0.9.2 kullanıyorum. Satchmo ile Temas adı verilen varsayılan modeli kullandım. Bir satchmo_mod uygulaması ve bir admin.py dosyası oluşturdum.fk_name 'kullanıcı', <class 'olan bir ForeignKey değil satchmo_store.contact.models.Contact'>
pip install django==1.3.1
pip install -r http://bitbucket.org/chris1610/satchmo/raw/tip/scripts/requirements.txt
pip install satchmo 0.9.2
django-admin.py startproject fk_test
cd fk_test
python manage.py startapp satchmo_mod
sonra oluşturmak admin.py:
from satchmo_store.contact.models import Contact
admin.site.unregister(Contact)
admin.site.register(Contact)
Sonra çalıştırın:
python manage.py runserver
gidin:
127.0.0.1:8000
bu hatayı alın:
fk_name 'user' is not a ForeignKey to <class 'satchmo_store.contact.models.Contact'>
Ben yığın izlemesinde bu hatayı görmek ve keşfetmek gitmeye başlar: İletişim modeli geri kayıtlı aldığında
/home/cody/work/martin-instruments/virtual-envs/mi-prod-copy/lib/python2.6/site-packages/django/contrib/admin/validation.py in validate_inline

GÜNCELLEME: Ben düzeltme Maccesch tarafından tavsiye etmedi . Ama Kişi nesnesini kaydını ve yeni satır içi ile reregistering sonra, zinnia kıracak bir şey yaptım görünüyor:
fk_name 'user' is not a ForeignKey to <class 'zinnia.models.Category'>
GÜNCELLEME: yeni bir soru başlatmak istiyor olabilir, emin değildi.
Bu
model ve modeladmin kodudur:models.py
class UserTaxExempt(models.Model):
user = models.OneToOneField(_User, primary_key=True)
tax_exempted = models.BooleanField("No taxes would be applied to purchases")
class Meta:
verbose_name = _('Tax Exemption')
verbose_name_plural = _('Tax Exemption')
def __unicode__(self):
if self.tax_exempted:
return unicode("Purchases are exempted from taxes")
else:
return unicode("Purchases are taxed")

Yani UserTaxExempt Kullanıcı ForeignKey vardır, bu yüzden olmamalı Bu iş iyi mi? Kullanıcı sayfasında çalışır, bu yüzden neden İletişim sayfasında işe yaramayacağını anlamıyorum.
? Hatayı gördüğüm tek zaman, Django iç işlevleri çağırıyor olmanız ve bu konsol çıktısının geri kalanında ne aradığımı bilmem. – Elliott
Basit bir ModelAdmin kaydettirmeye çalışıyorum. Ben modladmin'i çıkardım ve sadece tescilli olmayan modeli yeniden kaydettim ve bana yine hatayı verdi! Konsol çıktısı, yabancı anahtarları doğrulamak ve tüm değerlere/etc'ye bakmak için kullanılan validate işlevine iniyor. _meta.get_parents_list() öğesinin doğru şekilde oluşturulmadığı anlaşılıyor. Gerçek django dosyalarında yabancı anahtar doğrulamasını çıkardığımda (hatalı, biliyorum, ancak çalışıp çalışmadığını görmek için test ediyorum), site düzgün çalışıyor. Belli ki geçerli bir yabancı anahtar. Satchmo, bu sorunu çözen django'ya bazı garip düzenlemeler yapar mı? – Codygman
Elliott, gerçekten yapmaya çalıştığınız şeyin net olmadığını belirtti. Sorunuzdaki 'İrtibat' modeli, bu satchmo_store.contact.models' den hangisidir? Ve basit bir ModelAdmin'i kaydettirmekle ne demek istiyorsun? Lütfen sorunuzu güncelleyin ve daha fazla bağlam sağlayın. – Maccesch
