我的應用程序的一部分出現問題。一切正常,但是當我點擊一個名爲「koszyk」我得到的鏈接:Django'str'對象不可調用。如何處理它?

我用盡了一切,我無法找到任何東西......我所知道的是,問題是與模型「 koszyk',因爲一切運作良好。我希望你能幫助我。
我的文件: Views.py
# coding: utf-8
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from django.views.generic.simple import direct_to_template
from django.core.mail import send_mail
from django.template import Context, loader
from django.conf import settings
from sklep.models import Produkt
from sklep.forms import ZamowienieForm
def koszyk(request):
koszyk = request.session.get('koszyk', [])
produkty = list(Produkt.objects.filter(pk__in=koszyk))
if request.method == 'POST':
formularz = ZamowienieForm(request.POST)
if formularz.is_valid():
dane = formularz.cleaned_data
tresc = loader.get_template('sklep/zamowienie.txt').render(Context({'produkty': produkty, 'dane': dane}))
send_mail('Potwierdzenie zakupu', tresc, settings.EMAIL_SKLEPU, [dane['email']])
send_mail(u'Zamówienie', tresc, dane['email'], [settings.EMAIL_SKLEPU])
del request.session['koszyk']
return HttpResponseRedirect(reverse('sklep_koszyk'))
else:
formularz = ZamowienieForm()
if koszyk:
kontekst = {'koszyk': produkty, 'formularz': formularz}
else:
kontekst = {'koszyk': []}
return direct_to_template(request, 'sklep/koszyk.html', extra_context = kontekst)
def koszyk_dodaj(request, id_produktu):
koszyk = request.session.get('koszyk', [])
if int(id_produktu) not in koszyk:
koszyk.append(int(id_produktu))
request.session['koszyk'] = koszyk
return HttpResponseRedirect(reverse('sklep_koszyk'))
Urls.py
from django.conf.urls.defaults import * from sklep.models import Produkt
urlpatterns = patterns('',
url(r'^produkty/$', 'django.views.generic.list_detail.object_list', {'queryset': Produkt.objects.all().select_related('kategorie'), 'paginate_by': 1}, "sklep_produkty"),
url(r'^koszyk/$', 'koszyk', name="sklep_koszyk"),
url(r'^koszyk/dodaj/(\d+)/$', 'koszyk_dodaj', name="sklep_koszyk_dodaj"),
)
這將是巨大的,如果有人能幫助我。
您應該提供視圖的完整路徑。 –
Django框架試圖通過提供的'string'來查找'view',因此你將不得不提及全視圖路徑。如果'django.views.generic.list_detail.object_list'得到解決,您將需要交叉驗證。 –
此外,在Django 1.8中,您不能再使用字符串作爲可調用函數來查看函數:https://docs.djangoproject.com/en/1.8/releases/1.8/#passing-a-string-as-view-to-網址 – Brandon
