Python metodu invovasyonu, eksik parametre

Question

Bir profilleme sistemi uygulamaya çalışıyorum, böylece kullanıcı oturum açtığında, öğrenci öğrenci modelinden bilgi alır ve çeker ve onu ana sayfaya ve muhtemelen her birine döndürür sistem içindeki sayfa.

profile() missing 1 required positional argument: 'username'

urls.py

# student urls.py 
    # Import urls and patterns aswell as student views 
    from django.conf.urls import patterns, url 
    from student import views 

    urlpatterns = patterns('', 
    url(r'^(?P<username>[a-zA-Z0-9]+)$', views.index, name='index'), 
    url(r'^$', views.profile, name='profile'))

Answer 1

def profile(request, username):  

views.profile sen geçmemiş isteğiyle birlikte ekstra bir argüman alır.

url(r'^$', views.profile, name='profile') 

Answer 2

Sizin profile görünümü bir username bağımsız değişken gerektirir ama URL yapınızı tanımlamak etmez.

url(r'^profile/(?P<username>[\w\d]+)/$', views.profile, name='profile')) 

gibi bir şeye başında profile bölümünü hattını

url(r'^$', views.profile, name='profile')) 

değiştirme senin index URL'den ayırt eklenir.
