と書き、urls.pyには
from django.conf.urls import url from . import views urlpatterns = [ url('', views.IndexView.as_view(), name='index'), url('<int:pk>/', views.DetailView.as_view(), name='detail'), url('<int:pk>/results/', views.ResultsView.as_view(), name='results'), url('<int:question_id>/vote/', views.vote, name='vote'), ]
と書き、models.pyには
from django.db import models from django.utils import timezone import datetime class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0)
と書きました。チュートリアルの内容をそのままコピペしてきたので何が問題なのかわかりません。なぜテストでエラーが出るのでしょうか?
